PBCTRL and PREDICT

As an aid to those that manually tune their radio and point the antennas,
PBCTRL is able to display some useful information on the same screen as
the one used for display of the data from PB. The information is 
the antenna pointing data (azimut and elevation) and the 
Doppler shift for the downlink, presently 435 MHz.

The information is taken from PREDICT by John Magliacane, KD2BD and
it is displayed on the middle line of the PBCTRL screen where the name 
of the satellite is normally displayed.

A few requirements must be fulfilled in order for this to work:

1. Predict must be running in server mode (predict -s)

2. The name of the satellite served by PB must be the same as the name used by
   Predict. The name that PBCTRL uses in the request sent to Predict is
   the name defined by the parameter SATNAME, e.g. UO-22. The Predict 
   parameter 'Spacecraft Name' must be exactly the same as the PB parameter 
   SATNAME. As distributed, Predict will use a name such as OSCAR-22 for
   the same satellite. You can either set the PB parameter SATNAME to 
   OSCAR-22 or use the Keyboard Edit function in the main menu of
   Predict [E] to change the Spacecraft Name to UO-22. The important thing
   is that the two parameters have the same value, the actual value is 
   really unimportant since it is used for display purposes in both 
   programs.

If Predict is not running, not in server moder or the satellite is not served 
by Predict or the names do not match, PBCTRL will continue to run but only 
display the satellite name.
