Re: Mic bleed into audio during TX

 

I had this issue with all of my uBITX.? It started as very bad RF feedback, that I was able to reduce through proper grounding.? I traced it to RF getting into the shack on the coax shield.? Installed 4 ferrites before the coax goes into the shack and that seemed to solve it.? A common mode choke might have been a better solution.

I would look to RF in the shack getting into the audio of the uBITX.
