Mike,

That parallels my own problem 2 years ago, including the temperature effect.
It was the phase shift capacitor, which unfortunately is located inside the
rotator.  You can see it on the schematic.  You can get them from Yaesu, or
at least you could.  Replacing it is tedious, but the hardest part is taking
everything down to get at it. Some have reported you can "fix" it by
installing the capacitor at the control box.  I tried that, but it only
helped a bit.  It probably depends on the failure mode.

Subject: [amsat-bb] g-5500 EL help

Since my previously reported issues of intermittent Elevation control of my
g-5500 where it would work and stop based on heat of the day it has now
stopped completely and will no longer raise at all.

 

Can someone point me down the correct paths to start testing where my
problems are and if I need to send the controller or actual EL rotor into
Yaesu for repair?

 

Is there a good trouble shooting document somewhere?

 

Back to the Arrow for SATs for a while.  Does anyone need any specific grids
in Michigan I am willing to go activate on the arrow early mornings or
nights.
