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 the WSJT-X 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.

turn-key amplifiers can be ordered in one of the 3 color schemes shown below.
This photo is a good one to demonstrate the different color schemes the amplifiers can carry. For those wanting to match darker equipment, the black anodized finish at top left is a good choice.
Just below that one is an identical amplifier in natural aluminum anodized finish with black lettering. This is very close in color scheme to the one at the bottom, which is a light gray powder-coat finish, as is the one on the top right. The power supply (bottom right) is just a spray-paint finish (another shade of light gray).
The natural anodized with black lettering is an interesting finish, it's hue tends to reflect the look of surrounding equipment, and is also slightly responsive to different lighting in the room.
