returned from system software
Where: s = Satellite (a = Primary, b = Secondary)
p = Polarization (v = Vertical, h = Horizontal,
b = Band (h = High Band, l = Low band, u = USA)
m = Mode (v = Valid, i = Invalid)*
* The Mode bit is used to evaluate the Satellite, Polarization, & Band
combination vs. the Frequency/Symbol Rate/FEC currently in RAM. This bit will
be set to invalid if the Frequency for the selected combination is set to 0x0000;
otherwise it will be set to valid.
