"My suspicion (unconfirmed) is that the RFI might be generated by ballasts 
used for commercial grow lights in their fifty large greenhouses."

When they turn them on/off or change the configuration of the lamps, does 
the sound change?  Ten lamps, lotta noise, turn off seven, lessa noise, 
turna them all off, no noise?
