All:

Is there somewhere that one can find all the different  meanings of all the
different modes that the spacecraft transceivers  use.  For instance what is
Mode A, B, A/B, J and so  on?

Thanks

Hi Tyler.
 
This is a little historic.





Having moved away from these descriptions about 10 years ago they seem to  be 
returning.
 
Personally I prefer the more descriptive
 
Mode U/V     first letter uplink second letter  downlink    UHF up  VHF down
 or    L/S    V/U    S/X    etc etc.
 
Never could remember them then.......and  still can't now.
