Circuitry re-assembled onto a single circuit board

A project log for Basic HF Short loop antenna and some design notes

A portable loop antenna that works well on 40 through 10 meters. This basic design is advanced in my other projects.

The circuitry has been rebuilt onto a single board assembly.  This version has two latching relays to short link coupling of the coupling transformers when the antenna is in use (up to 100 W operation). Hopefully, this will protect the log amplifier and the clock board.

I have a video of the prototype in operation, but it is too large at the moment. I will resize it and post it later.
