9CAP Super question
 

I know this is an older technology radio but I just bought one (new old stock). I've just got it and see that it has an FM module on 50mhz channel 00. Hopefully the only change I will have to make to go to 72 mhz will be changing the module to a synthesized 72 mhz module on channel 48 which is the channel all my PCM receivers are on. I hope you will tell me there is no difference in the transmitter itself and only a module swap is needed. Thanks,

You are correct. Only the frequency module is needed.
