I’ve recently removed an old intercom and installed a flightcom 403mc used with my quite old microair 760 and rewired the input plug for the radio and seem to have gotten something wrong. The intercom works great, but the radio does not. It recieves and transmitts, however it only revieves scramble and only transmitts scramble. The problem is not with the intercom as I am having the same problem when I byepass the intercom entirely. Radio was working fine before. Any help would be greatly appreciated
