Are you calling me a liar Les?

Sure sounds like it from your instance.

I've been on tower talk for a very long time. And I know the history of the
OR2800 reports of slippage and the controller does not work.

I have had not had these problems.

Because the controller tends to miss and thus miscount the pulse counting
signals from the rotor and winds up displaying a different direction than
the antenna is actually pointing. Also, the circuitry in the controller that
provides the counting signal is noisy. In my case at times I couldn't hear
anything while the rotor was turning. Replacing the stock controller with a
Green Heron cured that problem as well as the miscounting issue.

The stock clamp does indeed slip no matter how it's torqued.
