Peter Do you have schematics and part numbers for the G-5500? I assume you are talking about a large wire wound pot inside the actual rotator vs the controller. I was think it might be something in the controller. I hope this is easy to replace. I have never had the G-5500 rotator disassembled. I had to send my EL rotator back to Yaesu 3 times last year. I had some bad experiences. My warrantee ran out about two years ago. I have already spent about half of what a new one cost.
Anyway, I can pull the AZ rotator on a warm day and find the wire wound pot that you mentioned. Did you replace the pot and the fluctuations disappeared?
I have been checking the dead band settings in the Nova program.
Thank you. Gary N0EZH -------Original Message-------
