I will sometimes scroll through the CB channels just to listen. My 10m inverted V antenna actually works quite well for 11 meters. I hear a guy from Puerto Rico on channel 9 quite often. He must be running a lot of power since he has an extremely strong signal. If I do get a CB radio, I want one that does AM, FM, and SSB.
I guess no one cares that the guy is on the emergency channel. I remember a time when one would get told to stay off channel 9 except for emergencies.
