I sold my old CB radios today on CL, $40 for both transceivers, with mics & several antennas. I'm not sure that was a good price but don't need them anymore. I got A+ in electronic class project 1969 used CB radio for mobile telephone I could make phone calls from my car. I tested the CBs last week to make sure they still work and they work good. Guy that bought them is actually going to use them. I told him it might be illegal he said, there mine now. That makes me wonder, I think they were 27 MHz but not sure. I wonder what those CB radios will interfere with these days?
