Richard,
	I've been doing some low break rate quenching tests today
using a +-10kVdc supply. I've been observing the gap voltage and RF
output. No matter what type of gap I've used, I see this type of spark
to a grounded electrode at these low break rate; of between 1 and 10
bps.

	It can't be an AC mains beat because I'm using a DC supply.
It's not the beat envelop because I still see it when the gap quenches
at the first beat notch. It didn't matter if I was using a 9 gap
cylindrical gap, a 6 gap commercial gap, a pair of carriage bolts or
my async rotary. (I just went out to the garage and double check this)

	Regards,
