Times once were that even the smallest stations had to hire overnight jocks or go off the air, or use really bad sounding analog automation systems that used to frequently screw up when no one was there...
Even if you had automation, you still needed to have a licensed employee there, as the phone transmitter controls hadn't been invented yet. But I do remember those clunky tape-based automation systems. They'd occasionally misfire and not stop on the tones, or two events would be triggered simultaneously, creating a crosstalk mix-mess. Usually it was the FM, while the jock did the live shift on the AM.
