very stripped down version I built with only the PIC16F876, MAX232 and 2N3904s

Norm,
Norm,
After many years, I homebrewed polarity switching into my old 2 meter KLM
antenna. The switching/matching system is made up of the matching coax, relay,
printed circuit board (PCB), and the baluns.
Here are several options.
1. Try to save the old hardware.
2. Split the antennas.
My mind is running wild.

he copied my CW on FO-29 using the TH-F6A or similar hand held.

Make your computer clock is synchronized with WWV exactly.
