Question about Cobra 150 GTL DX Base CB Radio
Do you have talkback installed? It my be too loud and causing feed back. Back the mic gain down if so.
Could also be improper mic wiring. If you use a mic that is wired for a different radio, it could just cause a hum, buzz or squeal.
Another thing that can cause a hum, buzz or squeal is a faulty volume and or squelch knob depending on the radio.
