1973.  My first CB radio was a JC Penny Pinto 23. Dad picked it up somewhere and brought it home for me.  There was the radio, a bit of coax, and a 102″ whip and mount.  I rigged it up in the garage, and went into a panic the first time someone answered my “breaker breaker 17” call.  I shut it off, and ran into the house.  It would be a few days before I became brave enough to actually talk with someone on the air, but eventually I managed.  I’ve been talking into some kind of radio ever since!
