2nd bearing
Saturday morning, Sept.15,2001, 10:00 AM.
Jeff-KD6TOJ and I started from a point just outside of Sonora. My 1st bearing, 2-degrees, was a little left of the actual direction.

Follow the 'blue highlight', this was our actual track as recorded by the Garmin StreetPilot-III.

Our 2nd bearing, 60-degrees, in Columbia, put us on the correct Forest Road. Credit goes to Jeff-KD6TOJ, for picking Italian Bar Rd.

As we approached the Fox, we received a lot of reflections at a critical juncture. Having four or five Forest Roads to choose from, we drove up road '3N03'. Taking our 3rd and last bearing, 120-degrees, it was quite clear we needed to turn around and head east on Road '3N11'.

Jeff-KD6TOJ was gracious and took the left photo of me driving up the trail to find a turn around point.

The right photo shows the Fox transmitter setup by Rich-KN6FW. 50-watts into a 3-element quad. Effective radiated power, 500-watts.

Equipment.
1) AHHA Doppler, very important piece of equipment. Particularly the multi-path meter, which told us when we could take a reliable BEAM bearing.
2) Arrow Beam, another important piece of equipment.
3) Garmin StreetPilot-III, even more important than the beam. This GPS street level mapping device had all the fire, forest and trails mapped out for us to follow.
4) Icom IC-R3, U-R-Here radio even worked with Rich's 500-watt transmitter. Stepping through the four internal attenuators, I was able to determine we were within a mile of the Fox when the IC-R3, in att-4, sounded off as we approached the transmitter.

I wonder if the posted sign, "No Hunting", means no transmitter hunting?

We had a long wait for the rest of the hunters to show up, about four hours worth of waiting.

Back into Sonora and all the traffic.

See you at the next "Challenge Hunt", Sept.29,2001. I was told this one will be a little north of this Sonora hunt and not so deep into the forest. Henry-KF6PCE will be the Fox.
