Hello everyone. I am new to the forums and I have a question for some of you Techs. I have a Connex 3300hp and it has no modulation(it does TX) keys up wattage and puts out a signal, just no modulation. I have done several voltage checks, and changed out the Audio IC because the PA wasn't working, but to no affect(put in new Ta72222AP)..right side of radio is getting very hot as well. It receives fine as well. It doesn't make any sound through the Talkback either. Any help or a point in the right direction would be greatly appreciated.
