Equipment used: 1) Initial bearing beam (4-elements) with Icom-R20 receiver and compass. 2) Laptop running DeLorme Topo maps and a GPS to plot my bearings. 3) Garmin SP2610 GPS with street level maps also to plot my bearings. 4) Doppler Systems Doppler w/Icom-R10 receiver. 5) MK4-Sniffer for my U-R-Here receiver. Works great. 6) MK4-Sniffer with beam (4-elements) to close-in hunt (walking) the Fox transmitter. Worked really great.

Johnathan-AE6HO wrote: The fox was placed in the center divide of Highway 85, just west of the major interchange with Highway 17 (880).  Access to this location was via the Los Gatos Creek Trail, which dips under the freeway here. The transmitter was 2.5 watts, "diagonally" polarized, and the J-pole antenna was placed on top of the metal barrier fence which prevents people from climbing up onto the freeway.  Only the tip of the radiating element was above street level.  Line-of-site distance from the Fremont start point was 16.4 miles. There were at least five different side-street approaches to the fox, only one of which would actually provide parking and foot access to the creek trail.  The minimum driving distance was 19.5 miles. (Actually, since the antenna was visible from the freeway lanes, one could have pulled over on the center divide of Highway 85, reached over the concrete barrier and touched the antenna, and have gotten about 18 miles.) One trap which nabbed two hunters was the fact that if one exited 17 onto 85 westbound, as might be indicated by doppler, he would be trapped for an additional 3.5 miles before he could exit and return east on 85, adding at least 7 miles to his score. An unexpected (by me) bonus was that all the passing vehicles on either side of the center divide were reflecting the signal at random.  Two hunters asked if I was AM modulating the fox because of this. Close in, the J-pole was coupling to the fence and the steel girders in the bridge span a few inches away, and the signal was also reflecting off the underside of the concrete.  A couple hunters walked right by on the trail with beams and loops and missed it their first pass. All in all, it was an enjoyable experience as a fox, except the slight nervousness of setting up an antenna and ammo box under a bridge, all the while getting funny looks from joggers and bicyclists going by :-) -Johnathan, AE6HO
