[amsat-bb] Optical shaft encoders

I would like to consider adding optical shaft encoders to augment or
replace the hall effect sensors in use on an Alfa Spid az/el installation.
We have the high resolution sensors and are experiencing some annoying
anomalies that have been very difficult to trace and are detrimental to
autonomous operation at our ground station at Virginia Tech.

Any information or help would be appreciated.
