[TowerTalk] Rotator controller buzzes

[john at kk9a.com]

If you have another rotator or GH box you can try swapping things around to
see if it is the controller or the rotator causing the issue.  I do not use
Hy-Gain rotators but I do own a lot of Green Heron controllers.  W2FU is
always very responsive and has good suggestions for debugging various
problems.

 Thank you, Charlie,
No the receiver is not picking it up.  You can actually feel the controller
cases vibrating.  I'll check the connections while at the remote.73  K5XM

 Do you mean a buzz in your receiver?

If it's your receiver while operating the rotator...I had such a problem
quite a few years ago.  I ended up "floating" the ground (common)
connection
in the rotator controller, i.e. no connection to the chassis in the
controller.
The only connection to ground/earth was then in the rotator itself.

With yours being an intermittent problem, I'd look for a loose or
corroded connection
somewhere in the wiring as you said.
