Hi All,
I bought a secondhand G5400B and promptly dismantled both rotators to
overhaul them and also completely repaint inside and out, and they
now look like new :-).
My question is I set the azimuth rotator as per the instructions and
all seems good apart from the CCW direction does not indicate 180
(far left), more like 165-170, is this normal? Mechanically it
rotates more than 360 but the resistance of the pot is 14 ohms CCW
and 8 ohms CW. I would have thought it should read 0 CCW then setting
the adjust pot on the controller to 180 with the rotator exactly 360
round CW. Hope I haven't lost anyone with this description :-).
Any guidance would be most welcome, thanks.
