Today I uploaded a YouTube video showing my YCCC 9 circle HI-Z preamp redesign
that uses a relay to ground the vertical during transmit, or when not in use.

I provide a link to the Kicad PCB files that can be uploaded to your favourite
PCB manufacturer if you want to build your own. I also provide a BOM parts
list detailing the parts needed. Total cost per amp including the PCB board,
enclosure and all parts is between $20-$30 depending on bulk componebt
purchasing discounts.
Construction and installation methods and ideas are also discussed.
