Tks again to all who replied.

I'm a little red-faced over this, as it turns out to be operator error.

During an earlier repair to the rotator control box, involving the limit window comparator chip, I tweaked pots, in other parts of the circuit, which should have been left alone.  At 5mV per degree of rotation, it didn't take much effort to get into the tall weeds.

In any case, one of the silver linings is that, independent of the manual, I think I now have a good working hallucination of how this thing works.

Are there other Prosistel owners who'd be interested in contributing to this good working hallucination?

If so, I guess the best place to reply is off-line, for openers anyway.

The second silver lining is that those clamps are much more rugged than I gave them credit for being.

Tks again & 73,

Dave, W8FGX
