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.

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. |
