More or less I am finishing with this small project (at least do not plan to do major changes to the mechanism). Made additional slot in motor's cogwheel
, so now each pulse is equal about 0,9* turning of the axis. Turning axis is now located inside the bottom feedarm. On the VIDEO
dish travels from 19,2*E to 12,5*W with stops on 9*E, 4*W and 11*W. LNBs are changing as needed. Do not have proper feedhorn for C-band LNB, but even without it possible to lock some C-band circular signals.
