Well if you want a discussion of sat names that aren't current, right now, my Drake has the following programmed on
C-band:
C4,G1,C3,T7,G9,G5,G8,E8,M2,E1,E2,S2,F9,S4,G4,T1,G3 ,T6,G7,T4,S3,F2,G2,
S6,F6,S9,A5,A6
and on Ku it has...
T7,G8,K2,T9,E1,E3,K1,K4,K9,T1,T6,G7,T8,K8,K5,K7,B6 ,G6,K3,T4,K6,A5
Only a handfull of these are the correct designations. Some are designations for sats that used to be there, and some are just other names I used when the available designations didn't fit new sats. Some are old sats I deleted and then re-used for newer sats. Recently I ran into the problem that I've run out of memory, and can't assign any new names, so I've had to delete some names I've used for sats over the Atlantic that I can't see anymore due to trees, etc. Anyway, it's amazing that I can remember what at least the C-band sats are, but the Ku sats, half the time I don't have a clue, I have to go to the C-band and then switch bands.
Anyway, being limited to designations that don't relate to the current sat names isn't limited to just 4DTV users, in fact they have more flexibility than most analog receivers.
