 Amateur Radio Station W6PQL

RF decks for the 600w amplifier for 23cm (50V LDMOS) are now available. (see the initial documentation here). Turn-key amplifiers like this one will begin shipping in April (2018); they can be ordered now (see info on the parts page).

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.

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

Turn-key 2 meter, and 222 MHz Kilowatt amplifiers are now in stock:


Latest items added to parts stock:

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).
