Re: Yaesu GS5500 gone cookoo



Hi Don and group.
I have checked the obvious things, I can't get the values right to calibrate 
the controller now?
My rotor never gives the correct value for zero degrees and keeps trying to 
find it!
Looking at other posts provided in the links I was sent it does sound like a 
dirty pot.
I'll let you know what the fault is when I can take it all down.
