I use a RAS SPID and have experienced these inaccuracies, reading the
SPID web site they recommend grounding both ends of the cables, but most
importantly using at least 14+ volts DC, then suggesting shielded
cables. I lost my station battery charger and didn't realise until the
RAS lost all calibration at 12 volts.
I have found if I can resist changing AZ and EL at the same time, I get
very few errors, however by adjusting both AZ and EL together you will
introduce errors, fortunately as we all know, it is a really easy fix to
recalibrate., I use the sun and watch the shadow til the antenna shadow
is in line, then adjust the 0, 0 and restart.
