Not only does it QSY the radio to each satellite as it
comes in view, but it also follows the doppler and
if you build a two triac interface, it will also dirive any
24 VAC TV rotator to track the satellites as well.

And it shows across the bottom of the APRS map
a display of all satellites that will be in view in the
next 2 hours.  ANd it will run on a 386 or old PC 24/7.

Or the whole web page

Donwload aprstk.zip from tapr. and unzip it into
an APRS directory and run APRStk.exe
