Me and my brother have PCI radios in our RZR 1ks. mine is new and working good and his is a few years old and were having some issues with it. the car to car radio burned up so were going with a hand held adapter to intercom for now while it gets rebuilt. Where our problem is that his radio is staying keyed up after he releases the pust to talk button. it was happening to the old radio and now the new hand held as well. every cable, button, headset has been replaced andit seems to do it still. it seems like a problem with the intercom because its the only thing left and if you unplug the adapter and just use the handheld, we can talk back and forth fine but when he goes through the intercom, he stays keyed up and you can hear him breathing and everything. the radios and website don’t have much for tech support and trying to see if its some dumb setting or something I’m missing. We don’t know much about these radios yet and plan on calling them Monday about the car to car and also this issue. any help would be greatly appreciated
