Interference:
Absolutely.   I put my AM/FM tuner up high on a shelf as it has a remote 
control
The T12 lamps I use in my workshop, repair bench setup, interfere with 
that tuner.
I  moved to a different shelf and ran a cable outside to an antenna to 
get rid of the interference.

Before I decided to move the tuner, I went into the fixtures and tried 
to filter out the interference... (and get better grounds)
  NO LUCK.
I didn't make LC networks... just Caps...
Felt it was easier to just move the tuner/amplifier unit. :-)

and the beat goes onnnnnn!
