Re: [amsat-bb] Still cannot receive NO-84
OK, I think I may have solved the mystery. I am seeing multi-channel PSK during the pass. Why someone would use multi-channel PSK is a mystery to me, but it looks like 9 channels.
Anyone seen that before?

2046 UTC, the bird went directly overhead. I was in listen-only mode. All I saw was (for the first 5 minutes of the pass) a series of lines which showed Doppler, almost like a yard rake was dragging at an angle across the screen.
What SHOULD I see?

Forgive me if I missed it on an earlier post, Mark, but what frequency are you listening on?

it's probably 9 different stations. multiple users. thats whats nice about this bird no CB like single channel FM birds where the biggest signal talks.

Well, the signals all start and stop at the same time, and are all equally spaced.
If this was HF only, I would say it looks like the PSK AFSK is overmodulated by using too much TX audio...

ahhh OK, did you see who it was to let them know?
