[TowerTalk] Rotor direction display is 90 degrees off

[Larry]

Check to see that the offset value is correct. Use the GH config program. 
(You can do it from the front panel but I forget how.)  I suspect somehow 
you set the offset value to 90 degrees. I have done it inadvertently. If the 
pot is bad it is unlikely to be off by exactly (or close to) 90 degrees 
consistently. I had a T2X pot get zapped in one area by lightning and the 
display would wander in value when the rotator was pointing in the direction 
of the zapped part of the pot (wandering could be anything from correct to 
off by +/- 60-70 degrees as I recall).

Subject: [TowerTalk] Rotor direction display is 90 degrees off

Is it possible that the pot inside my TailTwister rotor has moved? My
antenna direction on my controller now shows 90 degrees off (to the West)
for some reason. I climbed up the tower and confirmed that the mast has not
slipped in the rotator clamp or at the boom to mast clamp. I checked wiring
connections and all seems to be ok. Did the pot move 90 degrees? Anyone ever
see this before? I would appreciate any advice on this before I go through
the trouble of replacing the rotor with a spare. BTW, I am using a Green
Heron Engineering controller.
