Hey, this device has lots of stuff going on inside.  It is after all, a
computer.  There is probably an oscillator to generate a A440 signal,
perhaps some phase lock loops (old Hale SAT did) and who knows what else
indide.  I asked Paul for a schematic but they want to keep things
secret.  Anyway, put a radio next to your computer and listen.

My ham radio is useless next to my computer.  Mostly, it's the monitor
that affects the equipment.
