[Towertalk] Another Heavy Duty rotator...

Mine did too. Ham IV, DCU-1.
It was also putting the hash on the air when transmitting (NOT Cool).
Common point ground fixed it.
I got a 1/2" thick piece of copper plate at the local scrap yard (for free!) 
tapped 1/4-20 holes in it, got a bunch of 1/4-20 copper screws and now run 
all grounds separately to it.
If you go this route, be carefull drilling the holes.... The stuff grabs 
drill bits really hard and wants to turn YOU around. I finally went down to 
the local VoTech school and used a drill press. They were quite accommodating 
after I expained what I was doing.
