Ah, I found the old web page on the APRSdata engine that puts
out the local satellites-in-view to all mobile APRS radios in
the area showing the satellite in view, updated every minute on
the front panel of the radio:
1) Direction and distance to the bird
2) Downlink and uplink frequency
3) Current doppler for your location
4) Direction of movement in the sky

And if you have the D700 voice unit, the radio will speak
OSCAR-X HIGH, or OSCAR-X LOW as it moves across the sky... So
you don't even have to look at the display.

See the web page: http://www.ew.usna.edu/~bruninga/APRSdata.html

Only one person per region needs to run this, and it updates all
mobiles for the surrounding hundred miles.  You never have to do
satellite tracking again, yet you will be alerted to any
satellite in view while  you are mobile.

This program is over 10 years old, and someone should update
this for Windows...  And with a slight change in format, the new
D710 will automatically tune it.  I cannot make the changes,
since I lost the source code years ago.
