Or it could be moisture in the connector on the rotor. There are previous
posts in the archives on the Yaesu connector boot not adequately sealing and
causing indicator problems.

More likely it is an erratic connection on the wiper of the pot, somewhere
between the rotor and the control box. check the quality of all connections
before you reach another conclusion.

Jim,
I have tried recalibrating to inculde removing and replacing the indicator
needle as both of you mentioned. In fact, it was the first thing I tried. :)
But no, it's actually in the tracking between the rotor and the control box.
The antenna ( F12 C31XR), therefore the rotor always is pointing where it
should be at the ends of the rotor's travel. Since the rotor lived through a
lightning strike back a few years ago I suppose it's possible the pot in the
rotor has become erratic or damaged.
Thanks
