The ones at 710, 830, and 950 are exactly 120 Hz apart - 2x the US line 
frequency. The 350 and is 6x60 Hz away from 710 (and exact multiples of 120 Hz 
from all of the others as well).

You've got 950 Hz (the presumed fundamental), 950 - 120, 950 - 240, and 950 - 
600. Missing would be the subharmonics between 350 and 710 Hz (.

The second pair are almost 360 Hz apart. It sounds like there's some AC mixing 
going on.

Thanks for the tip.
Here is the episode.

Bill,
Do you happen to have an ALL.TXT on that situation? If so what was the 
frequency difference between those sub-harmonics?
