sBitx Mic input - assist request


 

I just realized your picture does not have RD2 in it. Perhaps different revisions of sBitx V3 ??


 

Yes, that is why I sent the picture.? Unfortunately, there is no tracking process for minor revisions, only the major ones, such as DE, V2, V3, and V4.? The V4 has just been announced.
?
With HFsignals, you always need to verify the schematic against the board.? My DE had some changes that have never been documented on a schematic.??

Was there a mic input modification for the sBtx DE because I am getting reports of bad or distorted audio.
?
The mic element I am using was the one that came in the uBitx v3 kit.
?
Was thinking of giving a Heil headset mic with the IC element in it a try. Just have to make a adapter cable for the PTT part and not short the mic.
?
Do you guys think thats a good idea?


 

I got this element and stuffed cotton balls in the housing and get GREAT audio reports?
