Butch,  Amsat would have this on their web page.  I do understand some
tracking programs are around that are pretty much command line items and
are accessible.  If you are just generating a set of tables and not a
graphic display these programs should work well.  

For casual listening I use the heavens above site centered on my qth.
It generates prediction data for visually viewing satellites including
the ISS but extending the time elements you can figure out in your head
when to begin listening and roughly where to point a directional array.
I can give you the direct link but need to go to a meeting for about 30
minutes first.

Try it on the hf side, that is the left  volume control.  Use the other
receiver for fm.  Anyone know how to find out when this bird is in
range.  Where do you guys get kep data and so forth.
