You may have noticed that
this is my favourite site for running a Multi-Event! It is
surprising that it is relatively unused by the general public and,
although there are paths, there are plenty of 'wild' areas where
equipment can be left without it being noticed by the few dog walkers
that do use the area.
Having tweaked by back a couple of weeks
before I knew that placing 10 Txs and Triffids was going to be a slow
process so I decided to set it all up on the Saturday.
Vaughn
and Debbie were returning for their 2nd attempt at RDF, their principle
target would be the the green Txs and I wanted them to enjoy all that
the wood had to offer, hence these were placed on the outside of the Tx
map. In order to give our 'Heroes' a bit of a challenge the
Ghost (1) was placed well away from the bulk of the Txs and in one of
the densest areas of undergrowth if you decided to approach it
directly, though just off the path if you studied the map and
approached from the South. At the briefing the competitors were
reminded that the 'Ghost' would shut down at 15:00 allowing time on
1910 KHz for the other reds to get much easier in the last hour. |

Colin: The
weather had been exceptionally hot for many days and Sunday 1st July
was no exception. Fortunately, Roy had chosen a woodland site for this
multi-tx hunt(in the relatively cool shade) and had also provided
several bottles of water anticipating several dehydrated contestants. On
this occasion Rosie wanted to try using my DF set (in case it had some
magic ingredient perhaps) so we agreed to swap sets. So I would be
using the other DF set which Rosie had built back in the 1980s (before
the availability of commonly-used receiver ICs). It was not as
sensitive as my usual set but quite adequate, I thought, for this type
of event. This meant that both Rosie and I were using sets which we
were not familiar with! (Not normally a good practice.) Roy’s
pre-hunt briefing included the warning that the difficult TXS (the red
ones on 1910kHz) were going to be particularly difficult. Given that
the site footprint was fairly small and the red TXs were going to be
extra “difficult” I decided to take the TXs in a strange sequence.
Usually I would find a group of three TXs then move on to the next
group. But today I planned to find only the green (easy and strong) and
yellow (moderate difficulty) TXs on the first pass. Then I would return
to each group again to find the red TXs on a second pass.
|
The idea was that, whilst most competitors were struggling to find the
red TXs, taking several transmissions to home-in, I would be able to
collect more points by going for more, simple ones. Of course that did
mean that I would eventually need to cover more distance than others
but hopefully the relatively late arrival at the red TXs would be
overshadowed by an earlier visits to the greens and yellows. It was
going to be risky – but nevertheless worth trying. At 1:30 I heard
all three green TXs from the start and sketched rough bearing lines on
a prepared map. In rough terms, A was to the east, F was south-west
and K was north-west, which indicated that it was across the road. My
joker was K and after the first 5-minutes everyone set off and I
crossed over into the northerly wood and headed to where my rough
bearing indicated. Tim was also heading towards the KLM group and we
ran to the northern edge of the wood as indicated by my initial
bearing. I recall only being seconds before Tim at station K. We both
relocated to another area further along a path to where we thought L
would be. When L transmitted, Tim got there first and then Rosie
appeared from nowhere. We both headed for where Tim had been. Although
Rosie had spotted the TX, I was lucky enough to find the Triffid first.
| |
While Colin explains his strategy 2nd and 3rd places review theirs. | Then,
to implement my master plan, I headed due south ignoring TX M and
heading for the FGH group. Back into the south wood. A few more
transmissions and F was in the bag, and a few more transmissions later
I found G. Then, ignoring H, I set off in a north-easterly direction to
find A. I
remember TX A going off when I was some 50m away. Using a compass I
continued along the sight-bearing line and found some rhododendron
bushes. I looked for a gap in the bush and went in. Amazingly I spotted
the A Triffid on the ground, without the need for a transmission! Then
I retuned for B (using a coarse manual tuning control!) and eventually
heard it, heading off in the right direction. I soon heard voices. It
was Roy, loudly encouraging Vaughn and Debbie to carry on after finding
the B station. They must have laughed as they saw me blundering about
(I could see the TX but not the Triffid) for sometime. After 3-minutes
I had finally spotted it at head height in a small tree. I
had now found K, L, F. G, A and B. Now was the time to go for the hard
ones. I may as well start with C since I was nearby. Waited for a
couple of scheduled transmissions but didn’t hear it so decided to
abort finding C and headed off towards H. Then, by some miracle, I
heard a feint peep from station C. I reverted to locating C and found
it a few transmissions later. I also heard the ghost at this time but
with only 20minutes of transmissions remaining it was dismissed as
unachievable. Then
I headed off for H and finally due north for M. M turned out to be in a
nasty, thorny area. This was close to K where I made my final TX visit
of the day to validate my finds and prepare for TX collection. This was
about 15:20. Hence about 40 minutes remaining. I could go and find the
remaining TX (the “ghost”) but, alas, it stopped at 15:00 so went to
the start to get a drink of water instead. |

- Vaughn had tales to tell too, bearing from France and an Organiser who
had forgotten where the Txs were, but Debbie had cleverly planned her
strategy to get the 'After Eighth' prize. |
The
Hero League
|
Once again Gary topped the score sheet until
the handicaps were applied. In fact his performance has been so good
that we have had to adapt the scoring to cope with him. He is almost
certain to reach his goal of 200 Hero Points when he runs the August
event and at that time everyone's HPs will be scaled back. In future
this will occur if any competitor exceeds a handicap of 150, see the
modified page re the handicapping system here.
Thanks
to all who came along to brave the unusual temperatures and hope to see
you on the next one. This will be organised by Steve in the Berkhamsted
area, at least two cars will be leaving from the Colchester so if you
want to book a seat(s) let me know.
Details for July 22nd 2018 here.
