Funny thing, in 1973 when I was a Test and Field Service guy at CCA in
Gloucester City for some reason there was always factory wide
interference on the reception of the country and talk radio stations,
only the FM rock stations had good reception on the factory floor.

Interesting that a Boonton Grid Dip Oscillator radiated better around
the plant than a 20 kW FM transmitter under test.  Of course, the
transmitters were tested into 3 1/8 line through the harmonic filter
into a completely shielded water cooled 50 Ohm dummy load.   The
Boonton GDO was, um....., a much better radiator.
