> The strange thing is that all other transponders that use 22000 2/3 8psk do work but this transponder doesn't. It worked fine until december 3rd when uplink moved to Vienna. I think they changed a parameter like rolloff or inversion and the dvb-s2 part of stb6100 is buggy.
Reviewing the code and having enabled debugging options for stb6100, I
am puzzled about the high bandwidth values.
I thought that the bandwidth of the frontend would always be around the
bandwidth of the transponder, plus some minimum locking range. 11303h is
a 26 MHz transponder, so I wonder about the excess in bandwidth: 39.7
MHz is requested, 40 MHz bandwidth is the result. I would expect a value
of 22 MSps * (1+0.35) Hz/S = 29.7 MHz (which is more than the
transponder’s 26 MHz, though ?) but less than 40 MHz as in the example
below. If too much bandwidth hits the decoder, it may be facing aliasing
from neighbor channels, but I don’t know if that is the root cause of
the problems. This is http://jusst.de/hg/v4l-dvb/ as advised by Manu.
Tuning to a 27.500 MSps transponder results in a whoppin’ 62 MHz
bandwidth setting. Is this reasonable?
