David,

I didn't mention it in the post, but I used a different gap for the higher-
than-120 bps work.  But I've done enough cross-checking with my
various rotary gaps to know that it's not affecting the results in any
meaningful way.

A sync rotary must have means for shifting the mechanical phase
of the rotor to match the incoming ac phase.  This can be done by
rotating the motor in a cradle, or rotating the electrode assembly,
or by shifting the relative position of the rotor on the motor shaft.
A synchronous motor can be purchased, or an induction motor
can be modified to make it synchronous, details in the archives.
