I have a summer house out in the southhampton sag harbor area and routinely bring the radio out. I have a gre-500 and have Suffolk pd trunk programmed in. I have no problem hearing them on the way out from Nassau. But I get no activity on at the summer house and even when I bring it in the car around town. I hear all the VHF UHF channels out on the east end with no problem. Just wondering what the issue might be.
