Extreme CHALLENGE hunt, put on by Rich-KN6FW.

For Johnathan-KG6KWT and I (Jim-KD6DX), this was an extreme challenge hunt. We both participated in the Cherry Lake hunt 'April 20' (very similar) and should have known better. I must not have learned anything.

I have included a TOPO map of our GPS track and terrain profile to the left. Also included are several of our bearings taken during the hunt. Those mountains sure gave us trouble, reflections all over the place.

Henry-KF6PCE taught me something new. I should have been watching the Fox signal strength as I was traversing those mountains. If I were climbing the same mountain as the Fox, I should loose the signal, because I would be under the radiation pattern and the crown of the mountain hides the Fox. If I were climbing a mountain opposite the Fox, my signal strength should increase because I'm gaining altitude and seeing the reflection better. Good tip Henry, now if I could only remember this next time.

Grizzley Peak was our best bearing but, we didn't know it at the time.

Deadend road
We ran across Paul Shinn on our way to the Fox, if only we followed him, we wouldn't have been last.

We also ran across many dead-end roads on our trek to the Fox.

Finally locating the Fox, with lots of help from Rich-KN6FW (Find Bear Creek Rd., stay on it, down turn around, I'm on the road), we found him (9:06 PM - Last).

EQUIPMENT:
1) 4-element beam: To obtain all my bearings.
2) AHHA MicroFinder Doppler.
3) Garmin StreetPilot-III: Street level GPS mapping.
4) Laptop Computer: TOPO map to draw bearings.
5) Icom IC-R3, U-R-Here radio. Full scale on attenuation-4 every-time we peaked out on a high ridge, 4.2 miles away.
6) Mobile radio, Standard C5900DA. Listen to the fox frequency and talk-in communications channel (simplex).

CONCLUSION:
1) Take BEAM bearings to the Fox, plot them on a map.
2) Check signal strength as you climb a hill.
3) Get better at educating your self, experience.
4) Ask for helpful hints when it get late.
4) Icom IC-R3, U-R-Here radio is still priceless.

Dinner was great, thanks Don-KD6IRE, for giving me half of your pizza.

We were so late, we closed the place down. See you at the Ron-N7TVE and Chantel, day hunt on June 29th. (click schedule). Chantel will be hosting some sort of PICNIC thing. Bring something to share.
