Its quite possible that the radio needs alignment. That freq. counter should stay rock solid in any mode because unlike any in line freq counter, instead of sampling the transmitted frequency it is taking a reference freq. off the PLL and adding a set amount. I believe the reference is 10.240Mhz plus the 2.5khz ssb offset and then the freq. counter board has its own mixer that converts the incoming signal to a usable reference. I can look up the specifics if you would like and give you a better idea of what to look for. But it could be either your VCO/PLL circuitry or the Freq. counter "controller"/mixer itself. But since you say the radio is off on tx freq and no one can hear you, I would bet on the PLL.
