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

["Greg D." <ko6th_greg@xxxxxxxxxxx>]

Hi Bill,

I've posted the basic stuff behind my controller at
http://home.jps.net/~gregd/hamsite.htm

Look for the links in the upper left-hand box.  The
controller isn't as inexpensive as Bob's, but it does
track close enough for AO-40.  Uses a serial port and
FODTrack in Yaesu mode (or anything similar).

Have fun,

Greg  KO6TH
