[amsat-bb] G5400B calibration problems

[Tim Goodrich]

Hello All,
I could use some help with the alignment/calibrating of my az/el rotor to my
rotor controller.

I followed the G5400B manual instructions and set the rotor and antennas to
the full south position. The meter indicated full stop at the south position
as well. I then depressed the azimuth control to bring the rotor around 360
degrees back to south. The first 5-10 seconds, the antennas moved and the
meter needle was not moving. However, when the rotation was complete,
although the antennas were pointed south, the meter stopped just a couple
degrees away from south, so I used the rear pot adjustment to zero it. 

I then swung the other way attempting to go back to my starting position.
After the meter hit full stop at south in the original position, I looked at
the antennas and they were about 45 degrees short of full south. 

According to the manual, I followed the steps correctly, but no matter what
I do, I cannot get the meter to always accurately reflect where the antennas
are actually pointing. 

Can anyone tell me what might be wrong?

Thank you,

Tim
