This sounds to me as if you were at a 60hz harmonic with the "beating" you
describe. My ARSG will do the same at the lower speeds. I suspect at higher
speeds  The window for a recognizable beat would be so small that it would
be impossible to keep it there long enough to hear it.

One interesting side note; I never noticed this before but as I'd raise or
lower the rotor speed, I could hear a combination or beat tone (where two
different frequencies partially coincide creating a perceived third tone
caused by the incidence of the two frequencies adding positively and/or
negatively). I would slowly change the rotor speed, attempting to
synchronize the two pitches. When this happened, (synchronize the two
frequencies and the beat tone goes away) even though it would only last a
few seconds, the coils output would increase dramatically, then decrease as
the two frequencies moved apart. Even the fluorescent tubes (which were
turned off but would still glow in the field of the coil) would get
brighter in step with the coil's output. Conversely, when the two
frequencies were at their maximum difference, the coil and the fluorescent
tubes were at their lowest output.

This effect was the most noticeable at the lower rotor speeds, in the
neighborhood of 60 - 80 bps. I know that one of the two frequencies I heard
was the sound of the RSG electrodes presenting and thus, firing, but am
unclear what the other sound was. Perhaps the output sparks from the toroid
itself?

Comments welcome,
