Hi, I', relatively new to sats and I'm still a bit confused about one 
topic and I would like to make this very clear in my mind....

It is regarding "uplink and downlink" mode configured for each satellite.

Ok for FM, SSB and so on.... But...


=> What about NORMAL or REVERSE doppler shift ??

=> When using SSB on transponder, what about when to use USB on uplink 
and LSB on downlink ??

=> When using SSB on transponder, what about when to use LSB on uplink 
and USB on downlink ??


I'm very confused if my doppler.sqf file is properly configured and a 
short explanation would be really appreciated.

I know this is a basic and fundamental question, but I really need to 
free my mind with this one.

Thank for your patience guys !

73 and Happy New Year 2010 !!!

I wish you health, health, health and more sats to come !!!
