This is a tcl script for Win32 that takes satellite azimuth and elevation from the Nova, Ham Radio Deluxe or SatPC32 programs and translates that information into the commands required to control antenna rotors modified with Tony Montiero's http://www.amsat.org/amsat-new/tools/downloads/iROTOR.pdf design. It reads the DDE sentences from the tracking program and issues commands to the iRotor's 'ROTOR.EXE' script.
