Temporary shipping halt from July 4th through September 15th (2022)

The shop will be closed for summer vacation during this period; orders can be placed and will be confirmed during this time, but I'll be unable to ship them if the order is placed after July 4th. Shipping will resume again on September 15th. I will be able to respond to inquiries via email during this period.

The 13cm couplers are back in stock

A 50w microwave relay PCB has been added to the parts page

RF decks and basic kits for the 600w amplifier for 23cm (50V LDMOS) are now available. (see the initial documentation here).

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.
