Hi guys.
When I press ptt i see tx on the screen but sound does not turn off and i see no power drain or power out on my meter
wiring is fine on the mic. Where woukd you start from to find the culprit?
it seems that components are crappy enough to have you fixing this piece of all ... the rest of your life
