The non-charming possible technical answer:
The electric company does not guarantee you 120 volts. It may vary a bit by location, but typically they guarantee something like 120 +/- 10%, which is 108 to 132 volts. They used to guarantee the frequency in the long term so that clocks that ran off of synchronous motors (used in schools and other government buildings) were kept accurate. I don't know if this is still guaranteed or not.
In the case of this radio station, I wonder if it is at the end of a long power transmission line. Perhaps the electric feed is less than the standard voltage?
