[amsat-bb] Help - Alliance U-110 as an elevation rotator

[Emily Clarke <emily@xxxxxxxxxxxxxxx>]

I'm mounting an old Alliance U-110 rotator horizontally to use as an 
elevation rotator, and I have noticed that if it is sitting with the 
mast clamp on the top everything works very well.  If it's flipped 
with the mast clamps on the bottom (so it can connect to the azimuth 
mast) it seem stall and jam.

I'm not sure if this is normal or just a sign of age but I traced the 
problem to a small gear under the shaft that "drops" when the rotator 
is in the clamp-bottom position and then slips over the top of the 
gear it is supposed to drive.

Since many people have used this rotator for elevation in the past, 
has anyone run into this problem before?  If so, did you find a 
solution for it?

73,

Emily
