I'm using only this patch to your source so I do not have distortion of
Did some more testing today with the following results:
1. My total cable between computer, rotor and lnb was to long. I could
see that my rotor signalled power low a lot and it was unstable with my
other dvb card. I pulled about 2,5 meters out of my ~30 meter long cable
and I had a stable power signal again all the way up to my lnb with a
rotor in between.
2. The mantis driver with "changeset 4491: 276006546e29
and the above path, does support DiseqC 1.2 now. I can control my rotor
without problems. So this is great news for me.
3. I have not tested this completely but I cannot get all the
transponders on each satellite. I tested Astra 19.2 and 28.2 so far and
not all the transponders can be tuned into. I will try to create a list
of working and not working transponders and post the result to this
list. Maybe my LNB is of because I have the same result within Windows.
Hope this is not a problem of the card it self.
