: I've started noticing that on 10 meters my top Yaesu G-1000 rotator has
: begun to emit broadband white noise when the antenna is actually
: turning.  Any ideas what the cause could be?

I would guess that it's white noise generated by arcing due to 
metallic/carbon debris on the motors rotor contacts.  I've noticed this with 
two DC motors over the years.
