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.
https://youtu.be/dl-crM5Kb6A <https://youtu.be/dl-crM5Kb6A> 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. 73, de steve ve6wz _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
