The mobile foxhunt was held on a glourious evening. The fox this year was Paul M0ZMB. There were four teams out looking for him. All the teams chose the same high point on the A38 to get the first direction.
As the my team was created from the guys who went to the Chantry we were the last of the teams to arrive at the high ground to get the first bearing. The first team were leaving when we arrived, the other two teams were still getting their bearings. We only managed to get a quick bearing before the first transmission finished.
Mark (M0RZS) was using a homebrew loop into a hand held, Roger (2E0FPV) was using a handheld and the body shielding to attenuate the signal and I was driving and drawing on the map. The car also had a mobile unit so we could monitor to ensure we did not miss a transmision from the fox.
The teams that left at the same time as us went in the opposite direction. Our second bearing was slightly off where the fox was hidden, so when we got to our third point we were expecting the bearing to be approximately due South to cross over where two previous bearings crossed. It crossed the first bearing line but further to the West.
We took our fourth bearing from outside the church at Cowhill. Even though the fox was reducing power by now the only way we could get a reduction in signal strength was to loose height. This was achieved by Roger (2E0FPV) putting his hand held on the floor and shielding the antenna. Mark (M0RZS) had to use the hill to get some attenuation but had strong signals all around.
To get to the church we had driven past the fox. So we had to turn around and found the fox in the Anchor car park.
I hope all the other teams had a good night as we did. Thanks to Mark (M0RZS) and Roger (2E0FPV) for the team work and company. Thanks to Paul (M0ZMB) for being the fox.
The picture shows the bearing traces made.
Traces on the map.

Useful for testing your equipment and map reading skills for the mobile fox hunt on Wednesday evening. Please leave a reply on the page if you pick up the beacon at your location also practise reading the Morse code sent.
This Wednesday just gone saw the start of the SDR-Kits R3500D ARDF kit builds and exploration of the Coilcraft RF Lab Kit which arrived a couple of weeks back. The RF Lab Kit includes Inductors (0603 to 2929), Low Pass Filters and Transformers.
Assembly of the kits has started with most members having placed the resistors.
Along with the Coilcraft lab kit came some T-Shirts too.
Please let me know if you need anything from the Lab Kit and I’ll guide you through it.
See link to the rally site and information. I am now going and happy to fill a seat if anyone wants to hitch a ride. Seems it may be a good rally this year given it’s anniversary year.
See me later at club.
