Current station information: Yaesu FT-1000D (for HF) and FT847 for VHF-UHF,Alpha 87A amplifier (3cx800 x 2) TOWER 1: 72 ft Rohn 55G - M2 RC2800P-A rotor,force 12 C49XR (49 ft boom - 14 elements 10 meters, 6 elements 15 meters, 4 elements 20 meters), MAG 240N (2 elements 40 meters), EF906 9 elements on 6 meters, 30 ft boom. TOWER 2: HDX555 - 55 ft crank up with MAG 330N - 3 element 30 meter beam, and Optibeam OB9-WARC (4 elements on 17 meters, 5 elements on 12 meters) 80 meter: 4 square array - using comtek. 4 full size elements of 1 inch diameter aluminum tubing,suspended from above by ropes which slope down from top of 160 meter vertical tower. verticals are ground mounted. 160 meter: 150 ft high tower - rohn 25G, with insulated section centered at 15 ft. downsloping radials. In line feed capacitor (resonant at 1600 khz otherwise) brings to j50 + 0.

Mountain top antennas (where my son anderew is sitting) is fed through 1200 feet of LDF7 (total loss 1.26 dB on 10 meters, .31 dB on 160 meters), and goes to top of 800 ft cliff just northeast of shack.There I have force 12 C3SS fixed on europe, sigma 40, and 70 ft vertical for 80/160.

7 beveredge directions (3 500 ft wires for E-W, N-S,NW-SE and SW wires are fed on each end with W9AY pre-amps and 9:1 xfmrs and terminatings resistors. I use remote relay switching to alternate feed and termination. I also use MFJ-1026 to combine beverdge signals for signal peaking and/or noise nulling. Top Ten auto band switch, writelog, dxbase, etc shack accesories.

Interests are band-countries, contesting, vlf (another story) and making my 80 and 160 antennas better and better. current band countries are just about at top of NW USA.

Contesting: 

First Place - North America - 1993 ARRL 160 Contest (prior call KZ3H)

First Place - #7 Call Area -2008  CQWW (all band) low power

First Place (with packet) - Zone 3 - 2005 CQWW 160 SSB

Non radio activities: I am the only physician in 35 miles in any direction in this beautiful place, along the Clark Fork river just above the point where it empties into beautiful Lake Pend Orielle, surrounded by spectacular scenery and wonderful people.
