[TowerTalk] Frozen Rotor

[Pete Smith]

My guess is binding that exceeds the starting torque capacity of the 
rotator.  The nice thing about the Yaesus is that they can stall for 
extended periods without damage.  I have accidentally left a G-800 running 
up against the stop for hours without (whew) damage, but have never found 
cold weather to impede turning in my setup, which uses a tubular sleeve 
that has plenty of clearance on my 2" mast.
