IC-F210 no AF out...
Recently resurrected an Icom IC-F210 440-490MHz LMR radio that had been reverse polarity connected and fried. Replaced the voltage regulators and the unit seemed OK. Programmed it up and onto the test bench. Radio TX's just fine but no audio out at all (including no BEEP and no EXT speaker).
The "BUSY INDICATOR" is constantly lit whether a signal is present or not. If I do TX into the radio with another unit the signal strength indicator lights up but still no audio out. Programming is pretty clean, no CTCSS or other tones and I've tried every combination of AF MIN and RF Squelch I can think of.
It's starting to look like a fault in the receiver with the BUSY IND always on - anyone got any ideas?
