RE: [amsat-bb] Computer-Controlled Rotor --- nuts to bolts

There's also this gem:

http://biology.campbell.edu/~hammond/ham/SAEBRTrack/

I'm just about finished brewing this up using old alliance rotors.
Seems to be working although it would work a lot better if I had a
G-5500.  But then again, I'm sure many problems are easily fixed by
throwing lots of money at them.

I thought I had another site that talks about taking the serial data
from Nova, pushing it back into the PC and using the parallel port to
control the rotors (through an interface box).  It's no longer in my
bookmarks, but maybe someone else has it.

This is not suitable for AO-40 or precise pointing to a few degrees.
But for keeping a UHF or VHF yagi on the fast flying LEO's it is good
enough and will run on any old PC (with DOS).
