Two transmitters used for this hunt:
#1 the Hard Fox transmitting 1-watt on 146.565 MHz.
#2 the Easy Fox transmitting 40-watts on 146.415 MHz.

My initial bearing to the #1 Hard Fox was 110*, which obviously was a reflection since the true bearing was 84*

Initial bearing to the Easy Fox was 90* (The true bearing was 91*).

I plotted a route (shortest distance) on my Garmin StreetPilot-III (GPS)which would take me out 10-miles on a bearing of 110*. Following the plotted route, my Doppler suddenly swung left towards Las Positas College. I couldn't believe my eyes, I wasn't expecting the Hard transmitter to be north but, my equipment was rock solid and pointing to the north. My U-R-Here Icom R3 was also beginning to sound off, indicating I should follow my equipment and abandon my initial bearing.

Most important pieces of equipment on this hunt was:
1) Icom R3. I used it as my initial bearing receiver on the 4-element beam and as a very reliable U-R-Here receiver as I got close to both transmitters.
2) Arrow 4-element beam.
3) Arrow 75db attenuator.
4) Magnetic compass.
5) AHHA Mirofinder Doppler. It definitely pointed to the transmitters and changed my direction of travel immediately.
6) Garmin StreetPilot-III. Auto routing the shortest distance to the transmitters and clearly visible, street level maps for me to follow.
7) Optoelectronics Scout-40. Frequency counter to sniff out, close-in, the actual transmitting antenna. I used it with my 4-element beam and attenuator.

Hard Fox #1
The winner, Dave-KG6ACD and Scott-KG6NXU said their most important pieces of equipment were:
1) Icom R3. Very reliable U-R-Here receiver, when you get close to transmitters.
2) Henry-II computer Doppler.
3) Radio Shack HTX202 receiver with a homemade modification to internally attenuate the RF signal.

Transmitter #2 (Easy Fox), was fairly easy to find

I used the same combination of equipment listed above.
In order of most important:
1) Doppler. AHHA Microfinder.
2) U-R-Here radio. Icom R3.
3) Street maps. StreetPilot-III.
4) Sniffer. Scout-40, close-in.
5) Beam. 4-element Arrow.
