WinListen, as part of SatPC32, will do the same. Choose the Window for two observers option. It's a great feature for any program, and one I've used often to find good windows to EU and mid-South America.

A friend who knows a little about ham radio asked me me about satellites. He asked a couple simple questions.- Can you work Alaska on the satellite ? When I answered probably. He said great - lets try it. I explained a little about orbits and then he said. Ok - so if you know you can work Alaska how do you know when you should try. Alaska is not all that far from my QTH here in Packer Country so for my example I have changed the question to "Can you work DK1TB on a satellite and if so which satellite and when is it possible ?".

We all know many ways to answer this simple question. Here is the easiest way I know. If you have an easier way please let me know.
