[Towertalk] Yaesu rotor makes odd sound

[TexasRF@aol.com (TexasRF@aol.com)]

All of the Yaesu rotors have limit switches inside. There is an actuating arm 
that is part of the 90 degree overlap feature that operates the limit 
switches. When the rotator is not at the limit of it's travel the arm is free 
to travel a small distance. The tinkling sound occurs when the rotator is 
shaken and the arm moves around inside the housing.
