Biography

I was first licensed in 1971 as WN7QYG. Upgraded to WA7QYG in 1972. Upgraded to Extra in 1981 and received call KU7Q.

Ham radio led me to a career in communications. I spent 20+ years as a comm tech or engineering assistant, and the last 19 as a comm operations manager with O&M responsibilities over 3 states.

I've always enjoyed the technical aspects of the hobby and mostly operate CW or FT4/FT8. I really enjoy designing and building unique station accessories based on microprocessors. One example was BlueLync. It was published in the February 2007 issue of QST.

I recently developed a multi-rig controller using the Teensy 4.1 processor and its companion audio interface board. It features CW and RTTY keyers and decoders, band stacking registers, touch-screen display with touch-tuning, audio spectrum display, separate DSP filters for each mode, push button selection of up to 16 rigs, a USB audio interface, antenna switch controllers to switch up to 8 antennas to a common port then route that port to the selected radio.

This project was published in the Sept/Oct 2021 and Jan/Feb 2022 issues of QEX. The firmware is open source and I can supply PCBs and enclosures if you want to build one for your station.

I've recently developed a smaller version of CTR2 called CTR2-Mini. It's based on the Wio Terminal from Seeed Studios and does a lot of what CTR2 does at a greatly reduced price. I've also developed an SO2R controller and dual-port antenna switch controller that combines two Minis, two radios, and multiple antennas into a seamless operating system. The CTR2-Mini project will be presented in the September 2022 issue of QST.
