[TowerTalk] YCCC 9 circle preamp redesign

[VE6WZ_Steve]

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.
