[amsat-bb] Re: Help with Yaesu g5500

Hi Mike,

If it works for a while and then quits, it kind of sounds like an over-temp problem in the rotor (or perhaps it *thinks* it's over-temp'd).  These motors aren't designed for continuous duty.  Maybe the switch is flaky, and cutting out early?

How much weight do you have up there, and how's the balance?
