Try to place on 1000pf (1nf) capacitor across the electret mic. Things should improve.
All the best. Regards

Hi all! I have just connected a bc645 4 pin electret mic to my ubitx and am getting a 5 tx/rx "chatter" on transmit on a dummy load, when press ptt. When i release, all is fine, rx is lit and i hear rcv audio. As a test, i enabled tx stop on the cec software, and pressed ptt.

What am I missing? ...continuing to read thread...
