Well, I swapped out our Novra S-75 for the Novra S-200 today,
which accepts and decodes the DVB-S2 format and the various modulation
schemes (8PSK, QPSK, etc etc).
I think I found a bug in the S-200 setup software: When it asks for the
symbol rate, I put in 6.349 msps. But after hitting OK and saving it, it
shows up as 6.348 msps on the screen. So I put in 6.350, and on screen, it
showed 6.349, and all was well. I've notified Novra support about that.
When I entered 1193.500 MHZ as the LF frequency, it chopped it off to
1193. Then, in the display, it said "1193 (+567 Hz)". Just out of
curiosity, I did "1194" and it locked it as "1194 (-433 Hz)". I see what
it's doing now. That can be confusing, but I know what it's doing and
I'll run with it. I assume, like the S-75, it adjusts if the source
frequency drifts.
Otherwise, my signal strength is now 76 with the S-200, compared to 80
with the S-75. VBER is still zero, however, and C/N is fluctuating right
around 12.5. I don't know what that means or if it's good or not.
