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.
