    N 37.55915, W 121.99260, CM97an  -  former call: WB6MYC

First licensed in 1964; assigned W6PQL in 2003, which was the call first issued to my late father in 1938.

Hobbies other than amateur radio include wine making, precision shooting, golf and tennis.  The children are all grown up now, on their own, and doing O.K. One daughter is an engineer, the other a CPA. Maybe now I can get my computer fixed and my taxes done...

The antennas are pretty modest, mostly small Yagis at about 33 feet. The antenna mast rotates through a bearing bolted to the apex of the roof (the rotator is located on top of a trellis).

Lately I've been experimenting with WSJT-X and WSJT 10.0 for EME work, and managed to work out some instructions for setting up the radios I use here. These instructions can be found under the "Current Projects" link on the left.

Station capabilities are listed here:

1.8-50 Mhz 144-148 Mhz 222-224 Mhz 420-450 Mhz 902-904 Mhz 1240-1300 Mhz 2304-2308 MHz 3456-3460 MHz
