The wife and I use cb radios to communicate when we are following each other on the road. She was following me the other day and I noticed something I had not noticed before. Since she was close behind me, I had my squelch cranked fairly tight, I knew I would be able to hear her but not much else. We were on a channel that did not seem to have much traffic on it, of course that could be any channel other then 19 here. I started hearing just a random beep, nothing else. I knew it was not her, her radio has no beep. I backed the squelch all the way down, and could faintly hear someone just over the ground noise, but I could hear their roger beep very clearly. My question is, is this normal? My thinking is that if this is normal, using the roger beep function may be a viable way to send morse code over a longer distance then voice. Granted I doubt this is legal at this time, but if SHTF it might be handy. Yes, I know a proper, licensed HAM rig is the way to go, but not all of us are there yet.
