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 !!!
