I have no static no matter where I set my squelch and RF gain. Both my rx/tx and antenna lights turn red when mic is keyed. Radio acts like no antenna is attached. Antenna mount is bolted straight through my bumper, so Im guessing its not a ground problem. Radio worked fine in my tractor, but cant get it working in my pick-up. Antenna wire is connector/connector type and seems to match my mount.
