[TowerTalk] HamIV Rotor sluggish

[Gene Fuller]

Hi Doug -

I believe that the "ham" rotators have a reputation for having the  brake 
wedge hang up in the gear, in which case rocking it back and forth a couple 
of time may free it up if your lucky. I have had this happen and rocking it 
freed things up. The cause is likely releasing the brake too quickly after 
releasing the rotator switch, i.e. trying to set the brake wedge before it 
has stopped rotating. A brake delay circuit mod is available from MFJ.
