Question about Radio Communications
I had a guy over the radio when I keyed it up and asked for a radio check he said I have no modulation only a carrier.
Sounds to me like you could have some bad coax,bad ground or bad antenna.

Assuming that you've tried another mike, the problem may lie in the speech amplifier circuit within the radio, something that will require someone with technical knowledge to repair.

there are several things that might be responsible for the absence of modulation when speaking into the microphone. a defective mic cartridge, a broken audio or audio shield/ground wire in the mic cable or mic plug or a defective push-to-talk switch in the mic itself, for starters. if all is well here then the amc and transmitter speech stages in the transceiver will have to be considered next. locate and check with a known good mic wired for the radio in question. let me know.

sounds like your Audio Output went out......not audio chip....may be your voltage regulator also....your voltage regulator IC is heat sunk....do you have a schematic?

Testimonial: "very helpful in narrowing down problem to repair"
The output stages were very poor on these radios and if it still has warranty I would contact Cobra for an upgrade or replacement....
