I just picked up this radio. Everything works but no modulation. Throws a strong carrier. Weather channels come in good, squelch works & scans fine. I've tried another mic, it is not the antenna, running off a pwr supply that works on several other radios. Everything external checks out. Internally nothing is burnt, soldering looks fine, nice cone shaped & shiny. Does anyone have any experience with this radio or suggestions what I can try? Tks in adv.
 

Is the other mike working on another radio? Two bad mikes sounds unlikely, but mikes break more often than radios. If the spare mike you tried is untested, that still leaves open this possibility.

The second mic did exactly the same thing as the original mic. I tested both mics and they are wired correctly.
