Mike, listen to it carefully, the switch picks a relay, do you hear the relay click? no ? clean the switch and look and the soldering/wiring to the switch, yes ?you do hear the click then its from the relay to the back, look closely at the relay contacts to the pc board and the wiring. Sometimes its very hard to see a cracked solder joint you might just want to resolder the contacts on the relay and see if you problem goes away. Kevin wa6fwf

I bought a used Yaesu g5500 and it has a strange problem. The AZ works perfect, but when I push the EL button it seems to work (ie. Move up or down) about 1 out of 4 tries. I can regularly duplicate the issue where I can't get EL to change. If I wait 30mins and come back then it sometimes works right away.
The rotor itself was into Yaesu and they said it was 100% perfectly fine. I have tried swapping the AZ/EL cables around and no difference.
It has to be a controller issue I think. Any ideas before I box it up and ship it to Yaesu to check?
When it works, it works fine and typically for 5-10mins straight, but then suddenly it will not change again.
