What are the advantages and disadvantages of computer control for doppler shift and tracking? is computer control of these parameters good enough that 2 stations could ragchew on ssb without manual intervention?
Properly implemented, computer control will provide:
* Rotator control, * Full Doppler correction.
And yes - you can rag-chew without turning too many dials but currently with FO-29 'resting' you'll only be able to use VO-52 and get up to 10-15 minutes quality time on a pass. (You shouldn't hog an FM-only satellite such as AO-51 or SO-50.)
P3E will be a different matter, you'll be able to talk for hours when it's visible.
