Could anyone please explain, in newbie terms, if it is possible to split a telemetry data stream from a satellite OBC into two data streams, sent simultaneously on two nbfm channels, each PSK with the phase difference between them?
I have in mind a conversation which I don't fully understand, about these being the I and Q components, and this offering a doubling of the data rate compared with using one nbfm channel.
Grateful for any pointers on or off the -bb
many thanks

Luc,
Sorry. In the heat of battle this morning I totally didn't recognise your call sign but thanks for the mode V/S contact on AO-51 just a short while ago!

Hi David
I just notice that but when i try to explain our previous QSO'S the satellite was below my wet roof top and it's kill all S band signal. Since about 5 passes i'm quite alone on mode V/S but i can test my new wifi beam and i don't know if an helix can beat it? The S band antenna is linear on AO-51 and as far i can remember in theory using a circular polarized antenna will induce about 3db of losses?
The fades a nearly gone on most of the pass but those remaining come from very bad antenna pointing on the satellite.
Hope to meet you again on the LEO'S
