I own the BR330T and I have fully programmed the scanner through my ARC program and mostly listen to police/fire/EMS but sometimes it just gets quiet out there. Sometimes I won't hear anything for 5 minutes and at other times for 15 minutes. It usually happens in the afternoon to early evening no matter if it's sunny or couldy and it's not constant. Could I possibly have something set wrong or is this common in certain areas? I live in Knoxville, TN. I use a 14" magna mount wide coverage antenna and it sits on the roof of my car.
