Hi and welcome to JustAnswer,

Initially, postback the brand and model of the CB radio.

Offhand, if it were a mic issue, possible suspects are:
  • open mic element (coil) (least likely);
  • faulty PTT switch (likely);
  • open white (audio) wire (most likely) either at the mic end or at the connector end.

A continuity tester (DVM/VOM) is needed to test all of the above. Please reference the wiring diagram of the RK56 below.

Another possibility to consider is an internal fault along the mic audio line inside the radio particularly the ALC; the modulation limiter control.

Good luck and thank you for asking JustAnswer.
