Okay this seems to happen alot. using my 396xt, I tend to listen to CHP on the 45 mile drive back and forth to work and home. When listening to CHP I get this cutting out about evey 3-5 seconds during a conversation. you hear then drop, then hear then drops, like someone is pressing the mic and releaseing it. It is not their lock freq tone either. I dont have anything in the background running, happens on a live freq. I dont have any priority channels set, so it is not that, it is only the CHP stuff it does it on, no other systems. It is so annoying, because you cant listen to anything. any ideas?
