Notes:
1. Organiser David provided a really interesting competition round the Bournville Garden Suburb of Birmingham. He started the competitors with an 80m couse with short duration transmissions followed by a Classic 2m race. The two competitions had no interval between the end of the 80m competition and the start of the 2m race
2. Click here for a map showing all the transmitter locations.
3. Organisers comments
*Carrying an injury. Does anyone else want to claim the same? Andrew notes that he was “able to run some of it” which is good news for Lithuania.
I printed 12 maps and we had 13 competitors – I count that a success. Running an event from home makes things very easy – and there’s an ice cold G&T ready as soon as all the Tx are collected in. Bournville is a very special place – and at 07:00 on a sunny August Sunday even more so. It was great to see the village come to life over the 2 hours of transmitter placing and I saw/heard my first urban raven (if you don’t include those at the Tower of London).
11 transmitters were deployed – all now of vintage age – and not a single failure. Plaudits to David Deane for his design and construction.
Congratulations to Jim – with a very painful knee got round the 80m in bronze medal position and completed the total course with just 2 minutes inside the time limit.
80m competitors noted unanticipated radio interference from the model boat club. #1 proved tricky – could it be the effect of the wire netting around the tennis courts? Also I should have explained the transmitted code – at least one competitor thought that number 1 was on for 40 seconds. For future reference – even with a very good Czech receiver #1 (740m) was not audible from the start but #4 (600m) was.
On 2m there was lots of noise from what we assume are switched mode power supplies and LED drivers. It seemed that #2 was ‘throwing its voice’ as some had bearings pointing toward #1 though as least one competitor stumbled upon #2 while seeking #1.
My expenses were minimal (batteries, tapes and printing) the balance will go into the equipment contingency fund – if we were to lose a Tx and an SI station at the same time that would be over £200 gone.
73 de M3WDD 4. The thanks of all the competitors go to David for organising an excellent day of radio sport.

4.  Alan Ball G3UQW 173.29 M?     5/7

Notes:
1. Organiser Dave repeated his successful formula from last year by running an extended sprint competition. The transmit times were set at 30 seconds in a 2.5 minute cycle which reduced the time wasted waiting for a 'target' transmitter to come on the air again. It is good to have variations to the basic IARU rules since this promotes extra interest.
2. Bucklebury is a lovely area although July means that the bracken has fully developed which slowed progress in some parts of the map which showed winter levels of vegetation.
3. It was good to see Colin and Rosie again and welcoming Alan Ball to his first event using the IARU rules.

Notes:
1. The transmitters had very varied audibility. TX 7 was only located by David M3WDD. Only David and Robin found TX 3 which was not audible from the mapped circle. On the other hand TX 4 was audible across a wide area and TX 6 also had good coverage.
2. The assignment of control codes to transmitter numbers was as follows:
TX 2 - 207, TX 3 - 208, TX 4 - 214, TX 5 - 215, TX6 - 211, TX 7 - 212. TX 1 malfunctioned with a broken battery terminal and all competitors were informed prior to starting.
3. The split times for the FoxOring race can be found here
4. It was a shame that so few people were able to support this event. Andrew, Jim, Stuart and Svet are all injured at present, Vlad is away in Bulgaria and Tim was at a family event.
5. The thanks of all the competitors go to David G6HGE for staging such an excellent event. Even the weather was 'wall to wall' sunshine.

Notes:
1. It was brilliant to be able to welcome so many newcomers to our minority sport. They should take great delight to find that they did not occupy the bottom 9 places in the 80m race.
2. Shoal Hill was being used for Direction Finding for the first tiem and proved to be an excellent area. On 144MHz the variation of signal strength was confusing with distant transmitters often being loud and near by transmitters being weak.
3. The thanks of all the competitors go to Andrew and Sonia for staging an excellent event.
4. David Williams triumphed again in both competitions being particularly dominant on 144MHz. David Heale and Adrian Bailey had outstanding runs on 144MHz.
5. Optimum sequence on 144MHz was 4-3-1-2-5 (or the reverse). Optimum sequence on 3.5MHz was 5-4-3-1-2 (or the reverse).

International British ARDF Championships 2017

The RSGB was delighted to welcome 6 overseas competitors to the International British ARDF Championships. The British weather was excellent and added to the enjoyment of three days of ARDF competition.

Day 1 - Sprint Race

Results and Splits

Notes:
1. The results and splits can be found on David Deane's web pages (link above)
2. Jillian set an excellent sprint course in the lovely grounds of Wycombe Abbey School.
3. In the competition the overall winner was again Andrew G4KWQ, who came home well clear of the 'pack'. From the visitors, it was Wolf Dietrich Barth who triumphed with a sub 30 minute time followed by the Tsenkov father and son combination.
4. The thanks of all the participants go to Wycombe Abbey School for allowing us to use their grounds and to Jillian for setting the course.

Day 2 - 3.5 MHz

Results and Splits

Notes:
1. It was a pleasure to be able to return to Swinley Forest at Bracknell for Day 2 (80m Classic Race) of the competition.
2. Visitor Tsenko Tsenkov from Bulgaria showed the field the way home. He was followed in by the tightly bunched 'pack' of M50 competitors
3. David Williams took the home honours with just over a minute in hand over Andrew G4KWQ and thus David wins the 80m trophy for the fastest UK runner in any class.
4. Svet Stoyanov planned the course, the transmitters were deployed by Erik Andersson (David's brother-in-law) and our thanks also go to the Crown Estates for permission to use the area

Day 3 - 144 MHz

Results and splits

Notes:
1. The forest at Hambledon is one of the finest examples of a Chiltern beech wood. We felt priviledged to be able to use it alongside the TVOC Orienteering event and our thanks go to Robin for making this possible.
2. With such open woodland, generally runnable in all directions, transmitter flags are easily visible from over 200m away. Planner Robin sited the transmitters so as to avoid this but it meant that competitors generally had to DF the transmitters down to less than 10m before the flags were visible.
3. Andrew G4KWQ came home well clear of the domestic field to retain the 144MHz plate. Visitor Viktor Tsenkov LZ3NN was his closest challenger, a couple of minutes behind.
4. Thanks go to planner Robin, to TVOC for allowing us to join their event and, of course, to the Hambleden Estate.

6.  Jim Smith G4DZL 48.38 M60     5/5

Notes:
1. It was a splendid day weather wise with sunshine and high spring temperature in abundance.
2. Everyone found all their transmitters inside the time allowed and that does not always happen!
3. The 2m race was incredibly close with David M3WDD just edging out Andrew and Robin.
4. With TX #4 being omitted for the short course, it was pretty obvious that this had to be at the top end of the long thin area. Transmitters 1 and 5 posed the greatest difficulty and one of them should have been 'bagged' on the way up and the other on the way back down.
5. TX #1, located in the steeply sided stream valley, posed the greatest challenge. Fortunately no one was stupid enough to attempt a crossing of the stream (more of a slow moving quagmire) and there was a lot of multi path propagation to be experienced as well.
6. David triumphed again in the 80m competition when he took just over 22 minutes to find all five transmitters. With the transmitters being so close to each other in comparison to a classic race, getting the sequence right was key. With TX4 needing to be either first or last the best sequence was 4-2-3-1-5 (or the reverse of course).
7. The organiser would like to thank all those who helped to pull in the transmitters at the end of the event. In addition Stuart G1ZAR, still suffering from his knee injury, is thanked for setting out a really 'fun' 80 m course
9. Split times for 2m are available . The splits for the 80m sprint are available here .
10. The mapping of control codes onto transmitter numbers was as follows:
144MHz: TX1=201, TX2=202, TX3=203, TX4=204, Tx5=205 Beacon=221
3.5MHz: TX1=206, TX2=207, TX3=208, TX4=209, TX5=210,

2. After the last event in Dec 2016, Andrew G4KWQ was complaining that he had lost his 'mojo'. He had certainly found it again over Christmas with a storming round of 48.04 - the fastest of the day by far.
3. Also putting in a fine run was Adrian Bailey, an occasional DFer from HOC
4. Medium course winner was Tim G4ARI and this was his first victory in an ARDF competition. He and Andrew picked up the prizes afterwards. Let's just say the awards were 'food and drink related'.
5. Apologies for the timing errors for TX 5, these have been corrected in the splits posted here.
6. Those inexperienced competitors who did not punch the finish having already punched the beacon have been re-instated with an assumed time for the short run betwen the two SI boxes.
7. Special thanks must go to John M0OJM who pulled this event back from the brink of extinction after the original organiser became unable to deploy the transmitters.
8. Thanks also to Andrew and Tim for collecting the transmitters afterwards.
9, Finally thanks to all the competitors who turned up on a pretty bad day weatherwise. It would have been too easy to just peer out of the window and decide to go back to bed.

2. It was a delight to be able to use an area like Long Valley courtesy of the Southern Navigators Orienteering Club who paid the huge fee levied by the MoD. Naturally we made a significant donation towards this cost. This was possible thanks to the higher than usual entry fee that we all paid. Our thanks go to SN for allowing us to join with them.
3. The turnout was disappointing given the quality of the competition. The thanks of all the competitors go to Michael for planning and organising the day, to Dave Deane for the loan of the transmitters and the timing equipment and to those who helped to recover the tansmitters afterwards.

Notes:
1. It was the very first 'outing' for Stuart's set of 144MHz transmitters. The 'gremlins' ensured that TXs 1 and 4 were not audible and a visit to them showed that the batteries had lost charge, possibly due to the transmitters not having responded to the SYNC signal the previous day and as a result operating all night.
2. The course was declared as 3 TXs being 2,3 and 5
3. David Williams managed to find TX 1 to add to his full tally of the official 3 to find.

Notes:
1. Planner's Comments

Having some on-going health issues (getting past it!) meant I was keen to organise something local and simple to set up, subsequently, my QTH was within the event area!
I also wanted to try an 80m urban event, explore the possibility of avoiding getting land permissions and 'borrowing' maps from Orienteering clubs by instead using open-source maps.
Not everything went to plan, but the story might be worth a future article!
Similar to the 80m 'sprint' format, two sets of five transmitters on different frequencies were used.
The first set were located in the semi-urban area of Mortimer with an intermediate beacon leading competitors to the more normal woodland terrain of Wokefield Common. The combination of the two areas together with the twelve controls to find meant there was the potential to over extend the competitors. A 30 second transmit time meant only waiting 2 minute for the next cycle and that helped to keep run times reasonable. 80m in normal UK woodland is usually fast and furiest however the complexity of the urban environment required good map navigation. Steve Chalk, who is more familiar with the open forests of CZ admitted his map skills let him down and this resulted in a seriously long run!
Many thanks to Colin, Rosie and Roy for travelling from Kent and making an impressive first appearance.

Click here for the 80m split times.
2. The results show just how challenging the event transpired to be. With extensive covering of bracken in the area now above head height in places, many of the controls could only be seen from as close as 3 metres away.
3. The intention of the combined 'Fox and Cubs' format was that competitors would carry receivers for both bands and make one circuit of the area picking up all the transmitters in one sweep. In the event, no one actually did this and so the results have been classified as a 144MHz competition with five transmitters plus the beacon plus a 3.5 MHz competition with four transmitters (following the failure of Transmitter 3 to operate) plus the beacon.
4. David Williams was the star of the day as he swept flawlessly round the area; most notably getting the 144 MHz transmitters in the optimum order.
5. Organiser John Little is having some serious knee problems at the moment and it was David G6HGE who literally saved the day by putting out the majority of the transmitters the day before the competition. The thanks of all the competitors go to David for rescuing the event.
6. By way of an experiment, Bob programmed the event into the software as three different courses in one event instead of three separate events. This was not a success and some competitors did not receive a print out of their efforts on both of the courses. Those who opted to do one course only were OK. The SI units that were placed with the transmitters have all been individually read out to provide the full data in the results.
7. The thanks of everyone who attended go to John M1SHE for his meticulous organisation and a day of radio sport on a fine sunny summers day.

International British ARDF Championships 2016

The RSGB was delighted to welcome 6 overseas competitors to the International British ARDF Championships. The British weather was excellent and added to the enjoyment of three days of ARDF competition.

Day 1 - Sprint Race

Results and Splits

Notes:
1. Organiser David M3WDD put all the slow keyed transmitters in the western half of the wood and the fast keyed ones over to the east.
There are one or two 'glitches' in the splits caused by differences in the time shown by the clocks on the SI boxes. The finish beacon was clearly ahead of the finish box, making it possible to get to the finish apparently before punching the beacon!

In the competition the overall winner was again Andrew G4KWQ, who, despite now being an M50, came home with just 3 minutes in hand over Robin Bishop.

Day 2 - 144 MHz

Results and Splits

Notes:
1. Few ARDF competitions in the UK are run over areas mapped to 1:15,000. Planner David M3WDD did a lot of work to negotiate access and to produce a composite map of the area.
2. The Wyre Forest was at its very best and many of the competitors admired the runnable area of beech in the north east of the area used (south of the old railway) with bluebells in theprime of their flowering.
3. Andrew G4KWQ retained the 144MHz plate for the fastest UK runner in any class while Wolf-Dietrich Barth DK7TD won the prize for the fastest overseas visitor.
4. David M3WDD is thanked by all the participants for planning and setting out the course.

Day 3 - 3.5 MHz

Results and splits

Notes:
1. Steve Chalk edged out David Williams to win the 3.5MHz trophy by a mere 36 seconds. Winner of the prize for the best visitor was Bernd Hofner
2. The lack of parking at the north of the area plus the fact that permission was not forthcoming for the north eastern part of the map, made planning and organisation difficult. The solution of a drive up to the start, followed by a finish remote from the assembly area worked well. In the competition, running past a transmitter that you needed to find meant having to retrace one's steps!
3. Andrew is thanked by all the participants for planning and setting out the course.

2. The first time anyone does a sprint course, the 12 second transmissions come as a huge shock. Peter, Adrian, Ian, Dave and Tom all faced this 'trial'. Peter did astoundingly well. After bagging three of the slow tranmitters on the north side of the road, he roared round the south side to get all four there, and get back seven minutes inside the time.
3. The SI box for the missing Fast 2 transmitter was used on the road crossing and therefore F2 in the splits does not score a point. The clocks in Beacon 1 and F2 were not quite in sync allowing David Williams to cross in zero time. He is good but not that good!
4. The map of all the transmitter locations is here
5. With hindsight and the actual race times, the sprint race should have been over a shorter distance.
6. Thank you everyone for supporting this event. The British Champs are next with a sprint race on the evening of Friday 6 May at Lickey (south west of Birmingham) and then classic races in the superb terrain of the Wyre Forest (west of Birmingham) on 7th and 8th May.

1. Organiser's comments:
Thank-you to everyone that came to the event to enjoy a days DFing on an area larger than we normally get to use.
The weather was kind to us, very mild and the rain holding off till when the last controls were being brought in. Surprising considering how close to Christmas we were.
In choosing locations for the foxes, my aim was to have those, not on the plateau, at least 10m below it to ensure they would be quiet in comparison to the others. 1, 2 & 5 were placed in a rough line from the start, with 2 below the plateau, to encourage the hunting of 5 before 2. 7 was placed on a low ridge to hopefully give some confusing multipath as the signal bounced around the larger valley. 3, 4 & 6, whilst tucked in close to the plateau escarpment, were placed with site lines along the escarpment in the hope that any multipath may emerge onto the plateau some distance from the fox location.
Thank-you to those that helped collect the controls afterwards, enabling us to be off-site well before dark.
A thank-you also to Southern Navigators for allowing us to to use the area in conjunction with their SN Trophy event.

Notes:
1. The 2m course required competitors to realise that TX #2 was both loud and to their right and even slightly behind them, as they crossed the field using the footpath. This meant that it had to be in the south east most block of the wood and therefore needed to be found first if the best sequence of visiting the transmitters was to be achieved. Having found #2, it was then a matter of resisting the temptation to zig-zag up the wood but, given that the finish was West of the start, to go up the right side to pick up #5 and then #1 before turning back towards the finish and going down the left side finding #4 and #3 on the way.
2. Competitors reported multi-path problems in the vicinity of TX #1 and #3, both of which were sited close to large heaps of overgrown quarry waste. These had complex contours.
3. David Williams came in the winner but his margin was a mere 25 seconds.
4. In the 80m Sprint/FoxO competition transmitter E was not audible from the circle as it should have been. It was positioned with a lot of screening in the direction of the marked circle. The organiser apologises for this.
5. It was the turn of Andrew G4KWQ to triumph in the 80m competition and his time of just over 24 minutes to find all ten transmitters was excellent.
6. The big surprise in the 80m competition was the third place snatched by newcomer and total 'novice' 'Zed'. A truly outstanding result. Getting home inside the time limit as well as finding them all, was the key to his success.
7. It was good to welcome four newcomers and to see Ian and Adrian competing again. Even the weather was as kind as it could be on the forecast cold and windy day.
8. The organiser would like to thank all those who helped to pull in all of the 17 transmitters that had been deployed. In addition John M0OJM, who ran registration and the 2m start, and Robert G3ORI, who sorted out the loan receivers and explained their use to newcomers, are both thanked for making the day run smoothly.
9. Split times for 2m are available here . The splits for the 80m sprint/foxO are available here .
10. The mapping of control codes onto transmitter numbers was as follows:

3.5MHz: A=206, B=207, C=208, D=209, E=210, F=211, G=212, H=213, I=214, J=215

Notes:
1. Vlad's idea of having the 80m sprint before the main 2m race won wide approval. It worked as a 'warm up' for the main competition.
2. The sprint transmitters were only visible from very short distances (six feet?) but the crystal oscillator was audible continuously from about 10m out and this told competitors which bit of thicket to look in.
3. Vlad used the large hill on the north side of the A3 to set a challenging problem of deciding on which side of the A3 TX5 was located. The hill generated significant multi path, especially to the east and south of the true location.
4. It was a great pity that the event attracted so few competitors to one of the better areas that we are able to use. Those who were unable to compete missed some top class DF.
5. The event was very slickly organised by Vlad 2E0VLB to whom the thanks of all the competitors go.

Notes:
1. The combined 'Fox and Cubs' course was clearly challenging as evidenced by the number of competitors who scrambled home just inside the 150 minute time limit.
2. Long Course winner David Williams was back on top form after his success at the Region 1 Championships in the Czech Republic last month.
3. It was good to welcome Dave and Zoe to their first event. Let's hope thay enjoyed their day out.
4. Cub F failed after Andrew's visit, consequently it has been discounted in the results.
5. The event was very slickly organised by John Little to whom the thanks of all the competitors go.

International British ARDF Championships 2015

The RSGB was delighted to welcome 3 overseas competitors to the bi-annual Festival of ARDF. The British weather was excellent and added to the enjoyment of three days of ARDF competition.

Day 1 - Sprint Race

Results and Splits

Notes:
1. Transmitter locations:
Click here for a map of the locations.

2. Other notes: Chipperfield is a quintessential English village with village green, cricket field and picturesque pub. It also has a small wood which is ideal for a sprint ARDF competition.
Organiser David G6HGE put all the slow keyed transmitters in the eastern half of the wood and the slow keyed ones over to the west. The wood has many paths and large runnable areas of beechwood, making it ideal for a sprint competition. The spectator beacon was on the edge of the cricket field.
There are one or two 'glitches' in the splits caused by differences in the time shown by the clocks on the SI boxes. The finish beacon was clearly ahead of the finish box, making it possible to get to the finish apparently before punching the beacon! These errors arose because the SI boxes for the forest were collected at Easter whilst the finish/start/Clear were only brought on the day. Hence the timing synchronisation was in error in one or two cases.
If there are some funds remaining after paying all the bills, then there is a proposal to purchase a Sport Ident SI-Master station which allows easy setting of the time in SI Control boxes without needing a computer or separate power supply. This will allow all the SI boxes to be retimed immediately before any future event.
In the competition Stefan Berse DO1FOX was denied the top spot by Andrew G4KWQ, who, despite now being an M50, came home with just 2 minutes in hand.

Day 2 - 144 MHz

Results

Split times

Notes:
1. Transmitter locations
Click here for a map showing the location of the transmitters.

2. Other Notes:
Wendover Woods present a real challenge for the competitor on two levels. First the two huge spurs and big dividing re-entrant in the south of the area, give rise to a lot of potential multi-path propagation and also severe screening of transmitters placed low down behind the spurs.
Competitors chose to either leave the start and run southwards on the west side of the western spur OR to head for the high ground near the forest centre from which reasonable accurate bearings to all the transmitters might be expected. It was roughly a 50/50 split between these strategies.

Placing TX #5 at the top of the re-entrant, where it was screened from the start and thius relatively weak at the start, was clever siting.
The second level of challenge was to identify which transmitters were sited at or near the tops of the spurs, so that a plan to minimise the number of climbs could be devised. Even when the actual locations of the transmitters is known it is not easy to decide the best sequence in which they should be visited.

The result was some of the best planning encountered in recent times at RSGB events.

Day 3 - 3.5 MHz

Results

Split times

Notes:
1. Transmitter locations
Click here for a map showing the location of the transmitters.

2. Other Notes:
Having two road crossings, spaced well apart by out-of-bounds areas, posed a real problem for competitors. They also had to decide if there could be any transmitters sited in the small parts of Common Wood that fell outside the 750m start circle.
In the event it is hard to see, from the split times, that anyone took the north western road crossing. The M70 category, who did not have to find TX#3, might have been best choosing the NW crossing. In the event neither of them did so.
Once again the planner had done his worst! Assuming you needed all 5 transmitters, the best thing to do was probably to go 3,1,5,4,2. There was a nice forest road between 1,5,4 but there was an easy route from 3 to both 1 and 4, so it probably did not make a huge difference if your choice was 3,4,5,1,2
All in all, another example of excellent planning which kept the competitors having to concentrate hard to choose a good sequence.

Notes:
1. It was a pity that so few people were available for an innovative event in a 'new' area.
2. Dave's idea of designating TX 5 as a 'beacon' radiating for one minute in every five from a location marked on the maps and then joining the 3.5 and 144 MHz courses, resulted in an 8 TX race on the long course and a 6 TX one for the medium course.

Organiser's Notes:
Uffmoor in the spring is a very lovely wood - perhaps we were about 6 weeks too early to appreciate the amazing variety of plants (wake up and smell the ramsoms) and wildlife (did any one else see deer or foxes?). Having the wood to myself as the sun was rising on Sunday was very special - not often that I find myself singing (and a mercy that there was no one else to hear). On balance though the terrain - even with its wonderful stream valleys - was just a bit to brambly and green for it to be fun ARDF.
I enjoy proper ARDF and I find some sprint races a wee bit too short and there is too much luck involves - so I planned our 80m sprint to be about 2km in distance so folks would have at least 3 cycles between transmitters - and I attached the SI units to slim trees and with the lock cables stretched as far as possible - all this to ensure that the SI Unit/Stake assembly was equally visible from all directions (I hate it when someone puts the SI/kite right up against a tree so only those lucky enough to chance upon the right direction of approach can find it first time).
Was it the right decision to have the 80m follow directly from the 2m? - with the short daylight available I think it was - it was starting to get very dim and murky when I finally left the forest. Putting a gap between the two races would have meant another hour or so. As we get more daylight into the summer - then this will not be a problem.
Congratulations to Stuart for getting the optimum distance on both 2m and 80m (Long Course) and Robert (80m short course). The short course 2m minimum distance was 2810m.
It was nice to see 5 newcomers to the sport - there is a big learning curve for ARDF - and it took me a couple of years before it really clicked - congratulations to Steve, Delia, David, Adrian and Peter.

2. Over the shorter 4 transmitter course, Tim G4ARI posted his first win. Newcomer Ian Gamlen gave a glimpse of his potential by coming in second in what was only his second event. Ian also got the sequence correct as 4,2,3,B, before running out of time and having to head for the finish.
3. The split times for the 144MHz competition can be found here .
and the split times for the Sprint competition can be found here .
4. Planning Notes:
TX #1 was placed close to the road in the hope that competitors would race past while it was off the air and then find it behind them when it fired up again.
The layout of transmitters 2, 3 and 5 was to challenge competitors to choose the best way to go round the lake. The north side was best and most people chose this route.
Placing TX#5 on the far side of the road caused the most hesitation.
The open nature of the woods with winter vegetation meant that some of the 'flags' could be seen from some distance.
5. Stuart G1ZAR (placing of sprint TXs) and John Marriott (permission and maps) are thanked for the help that they gave. Also much appreciated was the number of competitors who helped to recover all the transmitters which meant that we left the area by 1500hrs.

Notes:
1. Michael Dunbar seems to have a knack of taking us back to previously visited areas and then gives us an entirely new perspective. The 'off map' start location enabled him to utilise the whole of the smallish area. Frith Hill was superbly runnable at this time of year as the undergrowth dies down.
2. Svet had a great day to post a clear win over Andrew and Norbert on the Long 144 MHz course. These three were well ahead of the 'pack'.

4. The only long course competitor to get the sequence of transmitters right was Andrew G4KWQ. On the Medium course it was Dave Deane who covered the shortest distance.

3. It was good to welcome Ian Gamlen of HOC to his first event.
4. The mapping of the SI boxes onto transmitter numbers for 144MHz was as follows:
TX2=202, TX3=203, TX4=204, TX5=205
..and the assignment for the Sprint race was:
TX1=206, TX3=208, TX4=209, TX5=210.
5. Organiser John Marriott gave us an unusual 'all round' layout of transmitters and it was a bit of a surprise to be crossing into Martinshaw Wood and getting close to the M1
6. The failure of TX1 on 144MHz was unlike any previously encountered failure and the strength of the 'squegging' signal said there was not much amiss with the battery. This TX was sending the expected MOE at five minute intervals prior to start up.
The problem with Sprint TX2 was that the PIC clock had decided to run a bit off frequency and so the timing of the transmissions was drifting out of the correct position in the sequwence.
Thank you for your understanding of these issues.
7. The thanks of all the competitors go to John Marriott for organising yet another very enjoyable competition even if the weather did not co-operate entirely.

TX1=201, TX2=202, TX3=203, TX4=204, TX5=205
..and the assignment for the Foxoring race was:
TX1=206, TX2=207, TX3=208, TX4=209, TX5=210, TX6=211
5. With David M3WDD carrying an injury and Andrew G4KWQ not running, the field was more open than usual. Michael Dunbar triumphed in the Long 144MHz race and Norbert raced round the Fox O course well ahead of the pack.
6. The organiser David took us back to the delightful Whippendell Woods again with its extensive areas of runnable woodland. The thanks of all the competitors go to him for organising yet another very enjoyable competition.

"Wasted time on #3. Hovering 25m from #1 and #7. 150m from #5. Waiting in the D-shaped open area for #4 - #4 was so quiet and #2 so loud I thought I had messed something up badly with my first 'east of the road' bearing - so after not finding #4 before it stopped sounding I went and got 2 and then headed North the open up the bearing to #4 - ooops - right where I thought it was originally and then 8 - no problems"
5. A majority opted for an anti-clockwise circuit of the wood but there was a significant minority going in the opposite direction.

International British ARDF Championships 2014

The RSGB was delighted to welcome 4 overseas competitors to the bi-annual Festival of ARDF. The British weather was not the best although the worst of the downpours were avoided during the races.
The trophies, prizes and certificates were presented by the John Gould G4WKL, the incoming President of the RSGB

Day 1 - Sprint Race

Results and Splits

Notes:
1. Transmitter locations:
Click here for a map of the locations.

2. Planner's report:
We are still setting the ground rules for Sprint events, so once I had established the area I had a fairly free hand in deciding how to plan my course. Originally, I hoped to make use of the open heathland areas and the nice woodland in the south east, thus avoiding any road crossings. However, the Wildlife Trust could not give permission to access the more open areas, because of ground nesting birds (nightjars). So, rather than put all slow and fast foxes in one of the blocks of woodland, I decided to have the slow set in the north of the area and the fast ones in the south east. This involved crossing the road, and hence determined the layout of the start, finish and assembly. I also decided that a marshal would be needed to ensure that fast moving runners wearing headphones, in the heat of competition, could cross the road in safety.

I wanted to provide a worthwhile course for the best competitors, with a winning time somewhere around 30 minutes, but also to allow all classes to tackle as much as they felt comfortable with. This is why I allowed all participants to search for all foxes, so long as they chose those which they could visit within one hour. This avoided the need to specify several "courses" with less than 10 foxes, but having only a very small number of people competing in each class. I was well pleased with the outcome of this informal arrangement, and I believe it enabled everybody to experience an enjoyable course whilst providing fair competition.

Day 2 - 144 MHz

Results and splits

Notes:
1. Transmitter locations
Click here for a map showing the location of the transmitters.

2. Planner's report:
Postensplain is an area I helped map back in the 1990's. It is one of my favourites - particularly in the spring (while control collecting I got my count of British Wildflowers up to 10 I could identify and name and 5 new that I am researching). The 'secret' rocket testing station in the centre of the forest dates from WWII, when we looked in the library for large scale mapping - the map we needed was the only one missing from their collection. During mapping I came across sections of ruined fence, buried in young plantation and bearing the stamp "Ministry of War 1943". These were replaced by sections of new fence and the orange signs you may have come across - the new fence has now decayed and the spooks appear to have given up prosecuting transgressors under the official secrets act.

Interesting how strange the bearings to Tx3 seem to have been - certainly from #2 it was very quiet indeed. I expected it to be an easy control to locate - but on reflection it has no direct line-of-sight to #2 or #4. I have yet to work out how a certain competitor managed to get a bearing on Tx2 from Tx3 but pointing directly to Tx4

Day 3 - 3.5 MHz

Results and splits

Notes:
1. The total of transmitters found is understated by one for all competitors. This arises from the fact that there was a discrepancy between the identity of the actual Finish beacon and the identity expected by the computer results system.
2.Transmitter locations: Click here for a map showing the location of the transmitters.

3. Planner's report:
As a relative newcomer to course planning its especially difficult knowing it's a championship event. The temptation is therefore to make it more difficult. I resisted however, assuming the competitors would be operating at less than 100% capacity due to the previous days' efforts.
Age group courses were in line the official ARDF distance rules to ensure overall fairness and I hope I achieved that goal.
It wasn't the intention to cause confusion as to the relative location of the foxes with respect to the railway line. Since the start is very close to the railway and the only real contender for confusion was fox 2 I anticipated the decision that fox 2 was north of the line would be determined in about 90 seconds from the start. I'm not sure this worked in practice as I know some were hunting south of the line.
I pondered extensively on number 3 (and number 1 to some degree) being close to out of bounds areas but I decided that it would cause competitors to evaluate more carefully. My reasoning is that those locations would have been viewed as less likely choices and therefore more reliance on DF is needed.
Fox 5 I considered as a 'normal' location, nothing too taxing except perhaps the distance to travel. If 3 had frustrated some then 5 would have calmed them down somewhat! I wanted competitors to think it was located within an obvious group of trees 100 metres to the south. I don't know if it had the desired effect.
Being mindful of excessive running between the final fox and the beacon, (a previous error of mine) the beacon position became constrained to be where it finally was. It was handy as it provided a convenient walk back to the car however I appreciate the flow from final fox to beacon to finish was a little dependent on the actual final fox and the route chosen. Not ideal in retrospect as some competitors struggled to find the finish from the beacon, something to learn from!
Overall comments were positive but I would urge you to forward any constructive criticism to me somehow so that I (and others) can improve on future course planning.

Notes by the Organiser:
1. This was a later than usual start to the 2014 season of ARDF. We certainly enjoyed better weather than might have been expected. Heavy rain the previous afternoon and evening made studs the footwear of choice on the steep earth banks.
2. The topography of Irchester Country Park must be unique with the enormous parallel earth banks left over from iron ore extraction and now covered with mature trees.
3. I aimed to provide straightfoward courses with a minimum of 250 metres between transmitters, in this small area. At the same time a couple of 'questions' were asked of competitors. Transmitters 1&2 both dangled the 'run past' temptations. Being placed so close to the nearest path, competitors would get a 'straight ahead' bearing as they approached and then in no more than 30 seconds, this swang round by 180 degrees to lie to the rear. If the transmitter was not on at the time, then it was easy to roar past.
4. Transmitter 1 was placed on the edge of the quarry in order to give strong multi-path off the far wall of the disused quarry. This was to tempt the impetuous into making a foray down onto the quarry floor.
5. The three 'usual suspects' occupied the top three places on the 144Mhz course. It was interesting to see how much the placings changed when using the Sprint format. Norbert Linke is to be congratulated on his win, possibly helped by starting off in the opposite direction to everyone else.
6. Split times for both competitions can be found 144MHz here and 3.5 MHz sprint here .
Note the transmitter codes were as follows: 201= 144 Tx1, 202= 144 Tx2, 203= 144 Tx3, 204= 144 Tx4, 205= 144 Tx5, 211= 144 beacon. For the sprint 206= Tx1, 207= Tx2, 208= Tx3, 210= Tx5.
7. Optimum sequences were: 144 MHz 4-1-2-5-3 (or the reverse) 3.5MHz sprint 3-2-5-1 (or the reverse).

Notes:
1. What a fascinating competition! Michael Dunbar manages to give us a different perspective on Mytchett every time he organises an event there. His choice of start location this time gave us all a brilliant place from which to get an initial set of bearings.
2. The planning was superb. With seven hidden transmitters (for the long course) no one but no one saw the trick of getting Tx 6 first which allowed all the others in the eastern part of the area to be 'hoovered' up in a short simple loop. That was not the only trap. Hands up those who had to go all the way back to pick up 6 after the initial bearing to it was, for many, much further west than the true location. Merely looking at the distances covered tells you who it was who did a bit of zig-zagging!
3. Andrew G4KWQ posted another clear win over the long 144 MHz course. His run distance was as short as anyone's and with his speed even the youthful Norbert could not catch him.
4. On the short course nearly everyone went 5,2,6,3,7 with a 3.52km straight line distance. John Marriott had a good day to be well clear of the pack.
5. It was good to see Richie again and he was a tad unlucky to have overlooked the beacon when he had in fact done the hard part and found all the hidden transmitters.
6. Split time can be found here . Go to the 'Mytchett' page and click on the name of the competitor whose split times you would like to see.

Notes:
1. We rarely have problems with vandalism, particularly in a wood like Northaw Great Wood where the users all seem to be middle class dog walkers. TX3 on the 144MHz courses was removed from its original site, the banner placed in the bag with the transmitter, and the bag then flung into some brambles about 100 m from the original site. With the transmitter still sending (albeit without an aerial), it was a tribute to Dave G3ZOI's design that the transmitter was still audible. David Williams was the first to find it as a plastic bag under some brambles. Perhaps the culprit was a misguided 'eco warrior'? In future we might make more effort to have a notice on each transmitter stating that it is there for a competition and will be removed at the end of the day.
2. As a result of the vandalism, transmitter 3 has been discarded from the results. This is a bit hard on those who either found Tx 3 or spent time looking for it, but there is no realistic alternative.
3. Andrew G4KWQ posted another clear win over the long 144 MHz course. Also showing well on 144MHz were Stuart G1ZAR and Jillian M0JIN.
4. In the single class Foxoring event it was the turn of David Williams to race round to post a win
5. It was good to welcome Tony Corbett for the first time. He did amazingly well to 'bag' all the 144 MHz short course transmitters and second place to boot.
6. The thanks of everyone go to David Heale for organising and planning the event.

Notes:
1. Having six square kilometers of forest to run around is a rare pleasure in the UK. It was a pity that not more were able to participate in the event.
2. Star of the day #1 was Andrew who posted sub 8 minute splits for his first two transmitters and then never looked back. He posted a clear win over the long course.
3. Star of the day #2 was Jillian who, after a bit of a 'rocky' start to her first Tx, then cruised through the rest to post a well deserved short course win.
4. It was good to welcome Richie Judson for the first time. He did amazingly well to 'bag' all the short course transmitters and it was a pity he could not quite get inside the time.
5. It was also good to see Tony Green again. It was still 100 miles for him to drive to get to this western venue from Swansea.

Cannock Sun 4 Aug

1. This event focussed on technique and practice with the Region 1 Championships being held in Poland next month.
2. The morning involved two group exercises, which focussed on dealing with 2m multi-path propagation and with tracking down over the last 100m. A known location allowed the participants to check their received bearings against this and learn how the components of the vhf signals arriving from different directions can combine to give a false result. It was then possible to compare this to the terrain characteristics that caused the effect.
The 'last 100m' exercise used TXs with no flags so that the DF had to be 100% DF!
3. There was then a 144 MHz competition to cement the lessons of the morning. Five unmarked transmitters were set out, with no information regarding spacing. Torrential rain added to the competitors challenge and woes. The results appear in the table below.
4. Andrew G4KWQ set out an interesting challenge for the participants, virtually all of whom are going to Poland in September to pit their skills on an international canvas. The thanks of all who took part go to Andrew for his efforts.

Notes:
1. Getting the sequence in which to visit the transmitters was a real challenge. To get this absolutely correct for minimum distance involved going round anti-clockwise, since this did not add twice the distance from the beacon to the finish to the total. The only person to do this was Terence Hosking who made a welcome return to the sport after a break. He has clearly lost none of his skill.
Of all the rest who went clockwise, only David Heale and Bob Titterington got it right; with John Marriott, Robert Vickers and Stuart Tyler getting close.
The biggest pitfall was to go 6-1-3 instead of the shorter 1-6-3. It added just under 300m to the distance to be covered.
2. Black Park, being used for ARDF for the first time, proved to be a delight. Especially in the south of the area there were good sized blocks of runnable woodland and it was easy to lose touch with the map.
3. David Williams won the long course, continuing his streak of good form in his last domestic race before the Region 1 Championships in Poland in September. This clearly augurs well for his chances in the M50 individual competition. Bob Titterington came in just ahead of Robert Vickers on the Medium course.

5. The thanks of all the competitors go to Robin Bishop RS213497 for staging his first event and for organising such an outstanding day weather wise. All the competitors enjoyed an excellent day of competition.

Notes:
1. There are some benefits in this age of austerity! Two adjacent Local Authorities with contiguous County Parks, both decided to hand them over to the Greensand Trust. The result being that the old Stockgrove Country Park is doubled in size and gives a lot more 'scope' to DF competitions.
2. The combined area drew a lot of praise from competitors with the intricate contour detail and areas of runnable forest combining to make an interesting competition.
3. David Williams continued the streak of good form he showed at the Festival by coming in six minutes clear to take the honours on the long course. David Deane came in well clear on the Medium course.

International ARDF Festival 2013

The RSGB was delighted to welcome 20 overseas competitors to the bi-annual Festival of ARDF. Even the British weather rose to the occasion and instead of rain on the Sunday, fine, warm sunshine greeted the President of the RSGB, Bob Whelan, when he came to present the medals and trophies.
He last visited an ARDF event in 2002 when he tried his hand at 144MHz DF. This year he ventured out into the forest with a 3.5MHz receiver to successfully locate one of the hidden transmitters.
At the medal ceremony, Viktor Tzenko made a presentation on behalf of the Bulgarian National Society to mark the Centenary of the RSGB.

Day 1 - Informal Sprint Race

Results

Notes:
1. Apologies for the technical problems with some of the transmitters. Tx3 went off the air when the antenna became disconnected.
Having six transmitters to be hunted by all age categories meant that, in general, everyone was able to find them all within the time limit.

2. Transmitter locations:
Click here for a map of the locations.

3. Planner's report:
Leith Hill has some lovely intricate features which make a sprint race particularly interesting. One could do without the Japanese knotweed but at least the mountain bike trails mean that it is still possible to move through the areas affected.
The sprint format is new and some competitors did not differentiate sufficiently early, between fast and slow transmitters. As a result they found one or more 'fast' keyed transmitters prior to their first visit to the beacon. The information sheet made it clear that all 'slow' keyed transmitters were to be visited before the first beacon visit and all 'fast' keyed transmitters after this and prior to the second beacon visit.

Day 2 - 144 MHz

Results and splits

Notes:
1. Planner's Comments:
Regrettably the organisers could not obtain permission for the use of large part of the Winterfold and Pitch Hill map, which made the planning of the 144MHz course a difficult task. The only viable option for the planner was to place the Start in the middle of the map next to the OOB areas in hope that the competitors would not be tempted to cross any of them. An unusual extra "not transmitting" control was placed at the end of the Start corridor again to try to prevent competitors from entering the OOB areas.
TX4 was placed at the West end of the map for the faster groups but it was not a problem for most competitors. TX1 was the trap for many and most visited 3, 1 and 5 with three crossings of the deep valley instead of one. Some competitors expressed the view that TX3 was not easy to find but it was placed in a very easily accessible and runnable place with no reflections of the signal.
Apologies for the 30 min delay of the start partly due to the late arrival of a few competitors who had to be escorted from the Finish to the Start. This led to delay in placing the Beacon and the extra start control 206.
Special thanks to Jillian for organising the maps and all land permissions, to John for printing the maps and helping at the Start, to Dave for the preparation and providing the TX kit, to Bob for the whole organisation of the Festival and to all volunteers who collected the transmitters - Stuart, Simon, Steve and Svet.

Day 3 - 3.5 MHz

Results and splits

Notes:
Planner's Comments:
1.Holmbury Hill is generally a lovely open runnable forest with lots of paths, so the problem was how to make a challenging run, especially with many good runners only having to find 4 transmitters.
Firstly, like the 'grand old Duke of York', I marched them down to the bottom of the hill!, thus introducing a bit of climb.
Secondly TXs 1, 2 and 3 were fairly evenly distributed round the finish, making it quite hard to determine the shortest route.
On the day, I was quite worried that I had underestimated the climb back to the finish, but no worries, the competitors stormed back to the finish without too much problem. The main complaint was the difficultly in finding TX3, although I suspect this was mainly due to false bearings,taken under a nearby power line.

Notes:
1. Thank you to the 13 competitors who came along to the Burbage Common event. A sunny although cool day was enjoyed by all. One significant 'milestone' was that every single competitor located every single transmitter within the time limits. Well done all.
2. In the 144 MHz classic race, Andrew was very much back on form with a clear victory, in spite of not locating the transmitters in the optimum way. Other notable results were Vlad's third place and Jillian giving some of the 'boys' something to think about with her well deserved 7th (and very nearly 6th) place.
3. This was the first 'proper' sprint race staged in the UK, with a full set of purpose built transmitters. Fortunately they all functioned as they should and were easily audible over the whole of the competition area.
4. The winning time in the sprint race was about right. UK competitors are obviously not going to be as well practised as those who compete abroad, so a winning tme of 19.18 showed that the course length was appropriate.
5. The sprint results were very interesting and the merit order very different to the classic race in the morning. Svet ran Andrew very very close at the top of the table, but those showing excellent speed of thought and analysis over running speed included a very creditable M70 in the form of Robert Vickers, plus good runs from Stuart Tyler, David Deane and Jim Smith.
6. Thanks to those who went out to collect in the transmitters after the event was over. Andrew's achievement was to go out without the code to the security locks on the SI units, and coming back WITH the SI boxes having managed to 'unpick' the combination. That showed a hitherto unknown talent to add to all his others!
7. Split times for the 2m classic race are available here .

Notes:
1. That was tough! With a minimum of 8.44km for the long course competitors over heavily contoured terrain with a challenging time limit of 150min, only two long course competitors found all the transmitters inside the time. Michael Dunbar scored a narrow victory over David Williams in a close fought race,
2. The optimum order in which the transmitters should have been visited were as follows:
Long course 2m: 24315, 80m 24135. Short Course 2m 2315, 80m 2135
3. Split times are available here .
2m and 80m splits are in separate tables. Click the name of the competitor to display the split time.
4. The woods and terrain at Hindhead were wonderful for an ARDF competition. We are grateful for the help and assistance received from the Southern Navigators Orienteering Club with whom we shared the area on the day.
5. The thanks for all the competitors go to Svetoslav for organising the event which was a first for him. Everyone appreciated the challenge he presented.

Organiser's Notes:
1. Thank you to the 9 competitors who came along to the Bloom Wood event. We had a great day with mild dry weather, just right for running, and a woodland that was mostly dry underfoot, even with all the recent rain. Open beech woods and plenty of deer and wildlife to be seen.
2. The courses were planned to allow a shorter 5 TX circuit and a long 7 TX circuit. Those doing the long had to deal with the few muddy areas.
3. I set part of the Course late Friday afternoon out in the dark with a head torch (not great!), and discovered the I-buttons would not set, which was a bit alarming as I had no pin punches or back ups. Thanks to Dave Deane who came out late Friday night to meet me near the M4 with a replacement synch-button and some pin punches. This allowed me to get out early Saturday to finish putting out the other TXs and then go around and reset the ones from Friday. I just managed this in time for the scheduled start, much to my relief. I shall always attach pin punches in future just in case.
4. Thanks to Vlad who stepped in to cover registration whilst I was out resetting everything.
5. TX 7 was very weak, and not audible from start, but competitors did hear it as they got nearer. When collecting it looks like the ground-earth wire had come loose, and this may be the reason.
6. Thank you to Dave W, Mike and Robert who went out collecting after the event, that was a great help.

Organiser's Notes:
I was much relieved that suburban ARDF 'works'. Everyone solved the different challenges presented - building related multipath, interference and not being able to run straight down the bearing from Tx to Tx; Svetoslav said it took about half an hour to make the adjustment. We did not lose any transmitters and no markers were vandalised. Jillian noted that the running experience was more pleasant - fewer brambles and more time on good surfaces. I managed to hand out some ARDF leaflets to passing joggers. From an organiser's point of view living on the map, made control placement and collection easy - 10 Tx placed in 2 hours. Given the availability of street type orienteering maps (and OPEN STREET MAP) perhaps we should consider suburban ARDF for a future winter event as a lot of the short-daylight and inclement weather risk and worry is eliminated - especially if we are not piggybacking on an orienteering event. Congratulations to Mike on his victory. Nice to see Jim Smith back with us again. There were some interesting times - not least Svetoslav on 80m - and the first three finishers on 80m using loop antennas, which seem to give an advantage when seeking low power transmitters.

3. It was good to wecome members of TVOC to the event and hope they enjoyed their outing despite the weather.
4. The mapping of the SI boxes onto transmitter numbers for 144MHz was as follows:
TX1=161, TX2=162, TX3=163, TX4=164, TX5=165
TX1=A=151, TX2=B=152, TX3=C=153, TX4=D=154, TX5=E=155, TX6=F=156, TX7=G=157, TX8=H=158, TX9=J=159, TX10=K=160
5. Congratualtions to winners David and Norbert who both posted impressive times.
6. The Organiser wishes to thank Dave Deane for the loan of the equipment, various people for bringing spare receivers just in case, TVOC for obtaining the Permission and also for the loan of the Tent, Table, Emit, Computers and First Aid kit (how is the finger now, Michael?).
8. Robin did a sterling job organising the event single handedly which included deploying 15 transmitters in total. In spite of the less than idyllic weather the participants all had a very good day out and wish to thank Robin for his efforts.

"Wasted time on #3. Hovering 25m from #1 and #7. 150m from #5. Waiting in the D-shaped open area for #4 - #4 was so quiet and #2 so loud I thought I had messed something up badly with my first 'east of the road' bearing - so after not finding #4 before it stopped sounding I went and got 2 and then headed North the open up the bearing to #4 - ooops - right where I thought it was originally and then 8 - no problems"
5. A majority opted for an anti-clockwise circuit of the wood but there was a significant minority going in the opposite direction.
6. John Little is thanked for staging a challenging event over very nice terrain.

Results and Splits

Notes:
1. Transmitter locations:
Click here for a map of the locations.

2. Planner's report:
We are still setting the ground rules for Sprint events, so once I had established the area I had a fairly free hand in deciding how to plan my course. Originally, I hoped to make use of the open heathland areas and the nice woodland in the south east, thus avoiding any road crossings. However, the Wildlife Trust could not give permission to access the more open areas, because of ground nesting birds (nightjars). So, rather than put all slow and fast foxes in one of the blocks of woodland, I decided to have the slow set in the north of the area and the fast ones in the south east. This involved crossing the road, and hence determined the layout of the start, finish and assembly. I also decided that a marshal would be needed to ensure that fast moving runners wearing headphones, in the heat of competition, could cross the road in safety.

I wanted to provide a worthwhile course for the best competitors, with a winning time somewhere around 30 minutes, but also to allow all classes to tackle as much as they felt comfortable with. This is why I allowed all participants to search for all foxes, so long as they chose those which they could visit within one hour. This avoided the need to specify several "courses" with less than 10 foxes, but having only a very small number of people competing in each class. I was well pleased with the outcome of this informal arrangement, and I believe it enabled everybody to experience an enjoyable course whilst providing fair competition.

Results and splits

Notes:
1. Transmitter locations
Click here for a map showing the location of the transmitters.

2. Planner's report:
Postensplain is an area I helped map back in the 1990's. It is one of my favourites - particularly in the spring (while control collecting I got my count of British Wildflowers up to 10 I could identify and name and 5 new that I am researching). The 'secret' rocket testing station in the centre of the forest dates from WWII, when we looked in the library for large scale mapping - the map we needed was the only one missing from their collection. During mapping I came across sections of ruined fence, buried in young plantation and bearing the stamp "Ministry of War 1943". These were replaced by sections of new fence and the orange signs you may have come across - the new fence has now decayed and the spooks appear to have given up prosecuting transgressors under the official secrets act.

Interesting how strange the bearings to Tx3 seem to have been - certainly from #2 it was very quiet indeed. I expected it to be an easy control to locate - but on reflection it has no direct line-of-sight to #2 or #4. I have yet to work out how a certain competitor managed to get a bearing on Tx2 from Tx3 but pointing directly to Tx4

Day 3 - 3.5 MHz

Results and splits

Notes:
1. The total of transmitters found is understated by one for all competitors. This arises from the fact that there was a discrepancy between the identity of the actual Finish beacon and the identity expected by the computer results system.
2.Transmitter locations: Click here for a map showing the location of the transmitters.

3. Planner's report:
As a relative newcomer to course planning its especially difficult knowing it's a championship event. The temptation is therefore to make it more difficult. I resisted however, assuming the competitors would be operating at less than 100% capacity due to the previous days' efforts.
Age group courses were in line the official ARDF distance rules to ensure overall fairness and I hope I achieved that goal.
It wasn't the intention to cause confusion as to the relative location of the foxes with respect to the railway line. Since the start is very close to the railway and the only real contender for confusion was fox 2 I anticipated the decision that fox 2 was north of the line would be determined in about 90 seconds from the start. I'm not sure this worked in practice as I know some were hunting south of the line.
I pondered extensively on number 3 (and number 1 to some degree) being close to out of bounds areas but I decided that it would cause competitors to evaluate more carefully. My reasoning is that those locations would have been viewed as less likely choices and therefore more reliance on DF is needed.
Fox 5 I considered as a 'normal' location, nothing too taxing except perhaps the distance to travel. If 3 had frustrated some then 5 would have calmed them down somewhat! I wanted competitors to think it was located within an obvious group of trees 100 metres to the south. I don't know if it had the desired effect.
Being mindful of excessive running between the final fox and the beacon, (a previous error of mine) the beacon position became constrained to be where it finally was. It was handy as it provided a convenient walk back to the car however I appreciate the flow from final fox to beacon to finish was a little dependent on the actual final fox and the route chosen. Not ideal in retrospect as some competitors struggled to find the finish from the beacon, something to learn from!
Overall comments were positive but I would urge you to forward any constructive criticism to me somehow so that I (and others) can improve on future course planning.

Notes:
1. No fewer than 18 transmitters were deployed for the event and this was the first time a full 12 transmitter Sprint competition has been run in the UK.
2. The 144MHz courses were seriously hard as evidenced by the number of competitors who were over time and/or failed to find all their assigned transmitters.
3. On the 144MHz course, the clock at TX 5 re-set during the competition. David G3ZOI has calculated the times which might not be completely accurate but are consistent across the competitors who visited this transmitter.
4. Norbert and David M3WDD battled it out for top honours and ended up with a score draw!
5. Split times for the sprint competition can be found here and the 144MHz splits can be found here .
6. Optimum sequence was: 144 MHz 4-2-1-3-5.

Notes by the Organiser:
1. This was a later than usual start to the 2014 season of ARDF. We certainly enjoyed better weather than might have been expected. Heavy rain the previous afternoon and evening made studs the footwear of choice on the steep earth banks.
2. The topography of Irchester Country Park must be unique with the enormous parallel earth banks left over from iron ore extraction and now covered with mature trees.
3. I aimed to provide straightfoward courses with a minimum of 250 metres between transmitters, in this small area. At the same time a couple of 'questions' were asked of competitors. Transmitters 1&2 both dangled the 'run past' temptations. Being placed so close to the nearest path, competitors would get a 'straight ahead' bearing as they approached and then in no more than 30 seconds, this swang round by 180 degrees to lie to the rear. If the transmitter was not on at the time, then it was easy to roar past.
4. Transmitter 1 was placed on the edge of the quarry in order to give strong multi-path off the far wall of the disused quarry. This was to tempt the impetuous into making a foray down onto the quarry floor.
5. The three 'usual suspects' occupied the top three places on the 144Mhz course. It was interesting to see how much the placings changed when using the Sprint format. Norbert Linke is to be congratulated on his win, possibly helped by starting off in the opposite direction to everyone else.
6. Split times for both competitions can be found 144MHz here and 3.5 MHz sprint here .
Note the transmitter codes were as follows: 201= 144 Tx1, 202= 144 Tx2, 203= 144 Tx3, 204= 144 Tx4, 205= 144 Tx5, 211= 144 beacon. For the sprint 206= Tx1, 207= Tx2, 208= Tx3, 210= Tx5.
7. Optimum sequences were: 144 MHz 4-1-2-5-3 (or the reverse) 3.5MHz sprint 3-2-5-1 (or the reverse).

Notes:
1. What a fascinating competition! Michael Dunbar manages to give us a different perspective on Mytchett every time he organises an event there. His choice of start location this time gave us all a brilliant place from which to get an initial set of bearings.
2. The planning was superb. With seven hidden transmitters (for the long course) no one but no one saw the trick of getting Tx 6 first which allowed all the others in the eastern part of the area to be 'hoovered' up in a short simple loop. That was not the only trap. Hands up those who had to go all the way back to pick up 6 after the initial bearing to it was, for many, much further west than the true location. Merely looking at the distances covered tells you who it was who did a bit of zig-zagging!
3. Andrew G4KWQ posted another clear win over the long 144 MHz course. His run distance was as short as anyone's and with his speed even the youthful Norbert could not catch him.
4. On the short course nearly everyone went 5,2,6,3,7 with a 3.52km straight line distance. John Marriott had a good day to be well clear of the pack.
5. It was good to see Richie again and he was a tad unlucky to have overlooked the beacon when he had in fact done the hard part and found all the hidden transmitters.
6. Split time can be found here . Go to the 'Mytchett' page and click on the name of the competitor whose split times you would like to see.

Notes:
1. We rarely have problems with vandalism, particularly in a wood like Northaw Great Wood where the users all seem to be middle class dog walkers. TX3 on the 144MHz courses was removed from its original site, the banner placed in the bag with the transmitter, and the bag then flung into some brambles about 100 m from the original site. With the transmitter still sending (albeit without an aerial), it was a tribute to Dave G3ZOI's design that the transmitter was still audible. David Williams was the first to find it as a plastic bag under some brambles. Perhaps the culprit was a misguided 'eco warrior'? In future we might make more effort to have a notice on each transmitter stating that it is there for a competition and will be removed at the end of the day.
2. As a result of the vandalism, transmitter 3 has been discarded from the results. This is a bit hard on those who either found Tx 3 or spent time looking for it, but there is no realistic alternative.
3. Andrew G4KWQ posted another clear win over the long 144 MHz course. Also showing well on 144MHz were Stuart G1ZAR and Jillian M0JIN.
4. In the single class Foxoring event it was the turn of David Williams to race round to post a win
5. It was good to welcome Tony Corbett for the first time. He did amazingly well to 'bag' all the 144 MHz short course transmitters and second place to boot.
6. The thanks of everyone go to David Heale for organising and planning the event.

Notes:
1. Having six square kilometers of forest to run around is a rare pleasure in the UK. It was a pity that not more were able to participate in the event.
2. Star of the day #1 was Andrew who posted sub 8 minute splits for his first two transmitters and then never looked back. He posted a clear win over the long course.
3. Star of the day #2 was Jillian who, after a bit of a 'rocky' start to her first Tx, then cruised through the rest to post a well deserved short course win.
4. It was good to welcome Richie Judson for the first time. He did amazingly well to 'bag' all the short course transmitters and it was a pity he could not quite get inside the time.

Cannock Sun 4 Aug

1. This event focussed on technique and practice with the Region 1 Championships being held in Poland next month.
2. The morning involved two group exercises, which focussed on dealing with 2m multi-path propagation and with tracking down over the last 100m. A known location allowed the participants to check their received bearings against this and learn how the components of the vhf signals arriving from different directions can combine to give a false result. It was then possible to compare this to the terrain characteristics that caused the effect.
The 'last 100m' exercise used TXs with no flags so that the DF had to be 100% DF!
3. There was then a 144 MHz competition to cement the lessons of the morning. Five unmarked transmitters were set out, with no information regarding spacing. Torrential rain added to the competitors challenge and woes. The results appear in the table below.
4. Andrew G4KWQ set out an interesting challenge for the participants, virtually all of whom are going to Poland in September to pit their skills on an international canvas. The thanks of all who took part go to Andrew for his efforts.

Notes:
1. Getting the sequence in which to visit the transmitters was a real challenge. To get this absolutely correct for minimum distance involved going round anti-clockwise, since this did not add twice the distance from the beacon to the finish to the total. The only person to do this was Terence Hosking who made a welcome return to the sport after a break. He has clearly lost none of his skill.
Of all the rest who went clockwise, only David Heale and Bob Titterington got it right; with John Marriott, Robert Vickers and Stuart Tyler getting close.
The biggest pitfall was to go 6-1-3 instead of the shorter 1-6-3. It added just under 300m to the distance to be covered.
2. Black Park, being used for ARDF for the first time, proved to be a delight. Especially in the south of the area there were good sized blocks of runnable woodland and it was easy to lose touch with the map.
3. David Williams won the long course, continuing his streak of good form in his last domestic race before the Region 1 Championships in Poland in September. This clearly augurs well for his chances in the M50 individual competition. Bob Titterington came in just ahead of Robert Vickers on the Medium course.
4. Split times are available here . Click on the name of the runner for the split times.
5. The thanks of all the competitors go to Robin Bishop RS213497 for staging his first event and for organising such an outstanding day weather wise. All the competitors enjoyed an excellent day of competition.

Notes:
1. There are some benefits in this age of austerity! Two adjacent Local Authorities with contiguous County Parks, both decided to hand them over to the Greensand Trust. The result being that the old Stockgrove Country Park is doubled in size and gives a lot more 'scope' to DF competitions.
2. The combined area drew a lot of praise from competitors with the intricate contour detail and areas of runnable forest combining to make an interesting competition.
3. David Williams continued the streak of good form he showed at the Festival by coming in six minutes clear to take the honours on the long course. David Deane came in well clear on the Medium course.

International ARDF Festival 2013

The RSGB was delighted to welcome 20 overseas competitors to the bi-annual Festival of ARDF. Even the British weather rose to the occasion and instead of rain on the Sunday, fine, warm sunshine greeted the President of the RSGB, Bob Whelan, when he came to present the medals and trophies.
He last visited an ARDF event in 2002 when he tried his hand at 144MHz DF. This year he ventured out into the forest with a 3.5MHz receiver to successfully locate one of the hidden transmitters.
At the medal ceremony, Viktor Tzenko made a presentation on behalf of the Bulgarian National Society to mark the Centenary of the RSGB.

Day 1 - Informal Sprint Race

Results

Notes:
1. Apologies for the technical problems with some of the transmitters. Tx3 went off the air when the antenna became disconnected.
Having six transmitters to be hunted by all age categories meant that, in general, everyone was able to find them all within the time limit.

2. Transmitter locations:
Click here for a map of the locations.

3. Planner's report:
Leith Hill has some lovely intricate features which make a sprint race particularly interesting. One could do without the Japanese knotweed but at least the mountain bike trails mean that it is still possible to move through the areas affected.
The sprint format is new and some competitors did not differentiate sufficiently early, between fast and slow transmitters. As a result they found one or more 'fast' keyed transmitters prior to their first visit to the beacon. The information sheet made it clear that all 'slow' keyed transmitters were to be visited before the first beacon visit and all 'fast' keyed transmitters after this and prior to the second beacon visit.

Day 2 - 144 MHz

Results and splits

Notes:
1. Planner's Comments:
Regrettably the organisers could not obtain permission for the use of large part of the Winterfold and Pitch Hill map, which made the planning of the 144MHz course a difficult task. The only viable option for the planner was to place the Start in the middle of the map next to the OOB areas in hope that the competitors would not be tempted to cross any of them. An unusual extra "not transmitting" control was placed at the end of the Start corridor again to try to prevent competitors from entering the OOB areas.
TX4 was placed at the West end of the map for the faster groups but it was not a problem for most competitors. TX1 was the trap for many and most visited 3, 1 and 5 with three crossings of the deep valley instead of one. Some competitors expressed the view that TX3 was not easy to find but it was placed in a very easily accessible and runnable place with no reflections of the signal.
Apologies for the 30 min delay of the start partly due to the late arrival of a few competitors who had to be escorted from the Finish to the Start. This led to delay in placing the Beacon and the extra start control 206.
Special thanks to Jillian for organising the maps and all land permissions, to John for printing the maps and helping at the Start, to Dave for the preparation and providing the TX kit, to Bob for the whole organisation of the Festival and to all volunteers who collected the transmitters - Stuart, Simon, Steve and Svet.

Day 3 - 3.5 MHz

Results and splits

Notes:
Planner's Comments:
1.Holmbury Hill is generally a lovely open runnable forest with lots of paths, so the problem was how to make a challenging run, especially with many good runners only having to find 4 transmitters.
Firstly, like the 'grand old Duke of York', I marched them down to the bottom of the hill!, thus introducing a bit of climb.
Secondly TXs 1, 2 and 3 were fairly evenly distributed round the finish, making it quite hard to determine the shortest route.
On the day, I was quite worried that I had underestimated the climb back to the finish, but no worries, the competitors stormed back to the finish without too much problem. The main complaint was the difficultly in finding TX3, although I suspect this was mainly due to false bearings,taken under a nearby power line.

Notes:
1. The Oldham Club were as meticulous as ever in their preparation for this event. The thanks of all the competitors go to them and especially to Phil M0GIE for all the effort they put into staging such a good event.
2. Congratulations to David Williams for his double win. Philips Park proved to be far from an easy area for ARDF.
3. This event was the 'swansong' for the Olham Club who, after many years, have decided to move on to other radio activities. Over those years they have given enormous pleasure to those who have travelled to Greater Manchester to participate in one of their events. The thanks of all participants, past and present, go to the Oldham Club for their efforts.

Notes:
1. Thank you to the 13 competitors who came along to the Burbage Common event. A sunny although cool day was enjoyed by all. One significant 'milestone' was that every single competitor located every single transmitter within the time limits. Well done all.
2. In the 144 MHz classic race, Andrew was very much back on form with a clear victory, in spite of not locating the transmitters in the optimum way. Other notable results were Vlad's third place and Jillian giving some of the 'boys' something to think about with her well deserved 7th (and very nearly 6th) place.
3. This was the first 'proper' sprint race staged in the UK, with a full set of purpose built transmitters. Fortunately they all functioned as they should and were easily audible over the whole of the competition area.
4. The winning time in the sprint race was about right. UK competitors are obviously not going to be as well practised as those who compete abroad, so a winning tme of 19.18 showed that the course length was appropriate.
5. The sprint results were very interesting and the merit order very different to the classic race in the morning. Svet ran Andrew very very close at the top of the table, but those showing excellent speed of thought and analysis over running speed included a very creditable M70 in the form of Robert Vickers, plus good runs from Stuart Tyler, David Deane and Jim Smith.
6. Thanks to those who went out to collect in the transmitters after the event was over. Andrew's achievement was to go out without the code to the security locks on the SI units, and coming back WITH the SI boxes having managed to 'unpick' the combination. That showed a hitherto unknown talent to add to all his others!
7. Split times for the 2m classic race are available here .

Notes:
1. That was tough! With a minimum of 8.44km for the long course competitors over heavily contoured terrain with a challenging time limit of 150min, only two long course competitors found all the transmitters inside the time. Michael Dunbar scored a narrow victory over David Williams in a close fought race,
2. The optimum order in which the transmitters should have been visited were as follows:
Long course 2m: 24315, 80m 24135. Short Course 2m 2315, 80m 2135
3. Split times are available here .
2m and 80m splits are in separate tables. Click the name of the competitor to display the split time.
4. The woods and terrain at Hindhead were wonderful for an ARDF competition. We are grateful for the help and assistance received from the Southern Navigators Orienteering Club with whom we shared the area on the day.
5. The thanks for all the competitors go to Svetoslav for organising the event which was a first for him. Everyone appreciated the challenge he presented.

Organiser's Notes:
1. Thank you to the 9 competitors who came along to the Bloom Wood event. We had a great day with mild dry weather, just right for running, and a woodland that was mostly dry underfoot, even with all the recent rain. Open beech woods and plenty of deer and wildlife to be seen.
2. The courses were planned to allow a shorter 5 TX circuit and a long 7 TX circuit. Those doing the long had to deal with the few muddy areas.
3. I set part of the Course late Friday afternoon out in the dark with a head torch (not great!), and discovered the I-buttons would not set, which was a bit alarming as I had no pin punches or back ups. Thanks to Dave Deane who came out late Friday night to meet me near the M4 with a replacement synch-button and some pin punches. This allowed me to get out early Saturday to finish putting out the other TXs and then go around and reset the ones from Friday. I just managed this in time for the scheduled start, much to my relief. I shall always attach pin punches in future just in case.
4. Thanks to Vlad who stepped in to cover registration whilst I was out resetting everything.
5. TX 7 was very weak, and not audible from start, but competitors did hear it as they got nearer. When collecting it looks like the ground-earth wire had come loose, and this may be the reason.
6. Thank you to Dave W, Mike and Robert who went out collecting after the event, that was a great help.

Organiser's Notes:
I was much relieved that suburban ARDF 'works'. Everyone solved the different challenges presented - building related multipath, interference and not being able to run straight down the bearing from Tx to Tx; Svetoslav said it took about half an hour to make the adjustment. We did not lose any transmitters and no markers were vandalised. Jillian noted that the running experience was more pleasant - fewer brambles and more time on good surfaces. I managed to hand out some ARDF leaflets to passing joggers. From an organiser's point of view living on the map, made control placement and collection easy - 10 Tx placed in 2 hours. Given the availability of street type orienteering maps (and OPEN STREET MAP) perhaps we should consider suburban ARDF for a future winter event as a lot of the short-daylight and inclement weather risk and worry is eliminated - especially if we are not piggybacking on an orienteering event. Congratulations to Mike on his victory. Nice to see Jim Smith back with us again. There were some interesting times - not least Svetoslav on 80m - and the first three finishers on 80m using loop antennas, which seem to give an advantage when seeking low power transmitters.
