I have hauled out my spare 5400 rotor for field day and found I have a problem. The control box is not sending accurate readings to the computer. It works fine as far as the rotor and the meter readings. I know the problem is in the control box as the one I use for everyday operation works fine with this rotor. I have checked the voltages at the transformer and they are OK so I am now suspect of one or both of the pots that adjust output voltage. I when I connect it to just one side of the rotor I can not get it to adjust to 1023 in the calibration routine in the software. Connecting it to the other side shows the same result. What I do see is a value that bounces around at random.
I guess my question is does this mean that I have two bad pots or is there some common connection between the AZ/EL output that would exhibit this result. Any ideas would be greatly appreciated.
