The young man shown here has been collecting Social Security for a few years now, but sixty years ago, he was operating his own broadcast station, as shown in the July 1965 issue of Electronics Illustrated.

The transmitter had inputs for microphone and turntable (or tape) and radiated through the house wiring.  (But the magazine noted that if that wasn’t working well, a 5-foot antenna could be substituted.)  The power level was within FCC requirements, but it radiated a good signal throughout a house, dorm, or camp.
