RE: [amsat-bb] G-5400B voltages

[kb9cry@xxxxxxxxxxx]

Tnx to those who have responded.  A couple of folks have suggested looking into the smoothing factor settings.  I can say that no it's not that at all.  One can watch the output numbers on the rotator setup screen in Nova and see the az voltages jump around.  So other's have determined that the output voltage pot in the controller is bad.  I tend to agree with this.  Now, one more question for the group.

Can I replace the 5400B controller with a 5500B controller and still use the 5400B rotator?

Tnx to all, Phil  KB9CRY
