[PCR-1000] PCR 1000 control program

[Mark L. Hammond]

In summary:

1) In the tracking program, you enter the frequency of the object/satellite 
you wish to track
2) the tracking program calculates the change in frequency for that object 
using the Keplarian elements
3) the tracking program (magically) feeds the frequency to WispDDE via the 
DDE interface
4) WispDDE sends the adjusted frequency to the PCR-1000.  As the object 
moves, the relative frequency moves, and it keeps updating periodically.

Using the Wisp tracking program to feed WispDDE, you can do some fairly 
elaborate scheduling of multiple satellites (set their priorities, tell it 
to ignore passes that are below some elevation threshold, etc.)

Additionally, such a setup allows you to do some automated tracking of the 
satellites with rotators and directional antennas.  Here is my homebrew 
trackbox that does exactly this:

Admittedly, Doppler adjustments may be overkill for the weather satellites, 
but if you *can* do it, you might as well ;-)
