This was an excellent "Santa
Clara" hunt. Its amazing how challenging a simple hunt can get, just
by placement of the Fox transmitter. Gary-KD6UIR and Sherri-KE6BLX
(originally hunting in Los Angeles), did a great job. Looking at my "Entire
GPS track"
you can see a few mistakes and detours. My biggest mistake was when I
was on Hicks Road, (the correct road) early in the hunt and did not
continue driving. I ended up turned around, driving south on Almaden Rd and came in on Hicks Rd.
again from the
opposite side.
The "3D View" shows why. A
large mountain shadowed the Fox from where I was at on Hicks Rd.
(early-on) and I would not have heard the Fox for another 5-1/4 miles
(10-minutes). That's a long time not hearing the Fox signal. In
retrospect, I guess 10 minutes is not very long when testing a theory.
Time to make a note, IF YOUR EQUIPMENT (DOPPLER)
POINTS YOU IN A DIRECTION AND YOU COMMIT TO TAKING THAT DIRECTION, THEN
DON'T CHANGE YOUR MIND UNTIL YOU PROVE IT OUT. GIVE IT AT LEAST 10
MINUTES OR 5 MILES. This sort of sounds like my published hunting rules
#4 (SOME RULES).
Driving around like I did, allowed me to watch my
Doppler point towards Hicks Rd. My decision was not to go back the way I
came from but, to continue my trip around the mountain and eliminate
locations in the area while verifying the Fox was really in the hills
along Hicks Rd. I didn't want to get caught in the Hicks Rd. (any
mountainous road) tunnel where the Fox signal will always be in front of
you.
The GPS StreetPilot-III really helped with plotting
street level routes in this hunt where I had no knowledge of the
territory or area. |

Equipment I used.
1) 4-element beam: To obtain
my initial bearings and for close-in work.
2) AHHA
MicroFinder Doppler. Very helpful.
3)
Garmin StreetPilot-III: Street level GPS maps and auto routing short
hops (shortest distance) towards the Fox.
4) Icom IC-R3, U-R-Here
radio. Tells me in four attenuation steps how close I'm getting to the
Fox.
5) Scout-40 frequency counter,
connected to my 4-element beam and used as a close-in sniffer.
6) Mobile radio, Standard
C5900DA. Listen to the fox frequency, talk-in communications channel
and used 446.000 Mhz as a private communications channel with other
hunters.
CONCLUSION:
Follow my original four rules published (here).
My initial bearing was 120* and I was only off by 10*.
Rule #1) Follow your initial bearing.
Rule #2) Get back on, your initial bearing.
My Doppler pointed to the Fox until I lost the signal.
I was on the correct road, Hicks Rd. but, turned around when I couldn't
hear it.
Rule #3) Trust your equipment.
Rule #4) Check your immediate
options before committing to a new direction and Once you commit to any
direction, don't change your mind until your prove it incorrect. You
don't want to return to the area you just came from.
Other than not following my four rules and there are
only four rules (I didn't follow any of them), I did okay coming in
second place.
