I think you mis-read what was said. The comment was about obtaining
the "orbital location" data from the datastream and comparing it with
the motor position value that we intended to send the motor to. The
two values will never match when you use an offset LNB setup. The
other problem is that I may have to nudge my motor position a fraction
of a degree to compensate for a possible non-plumb dish-setup (like
87.1 instead of 87.0).
I think we should stick with the "satellite_NIT == requested_NIT" method.
It might also be a good idea to put in a bypass for the possibility of
a poorly configured uplink provider not putting in correct or
