I live right across the river from the guy who started this thread. I have heard the same thing. They kept mentioning guard. I always thought it was someone's callsign. Now I know it's the channel's official title. He's right though, it does happen a lot. You know, one channel that I read about online once was 123.45. I read that it is kind of an aeronautical cb, used commonly for nonessential comms like chitchat. I know it must have some other designation like a nonemergency calling channel or something, but I wasn't sure. Anyone else hear anything on it? I've heard some stuff, but not very often, and some of it was not coming in well, so it was hard to understand.
