got myself a Technotrend DVB-C C1500 card, which has a TD1316AL/IHP
tuner, but the card doesn't really work on Linux - a huge surprise
there. It appears, the card is of a newer variety, which has some
incompatible component change. Using kernel 2.6.24, from what I've tried
the status seems to be:
- QAM64 channels work, ie. FE_HAS_LOCK but "unc" is very high
- QAM128/256 channels get only occasional FE_HAS_LOCK, but lose it in a
QAM64 high unc value is fixed by letting the corner detection stay on,
as reported in
QAM128/256 tuner locking can be fixed by reverting the patch in
but "unc" is still at unacceptable levels.
Increasing the tuner charge pump values as in
doesn't seem to help at all.
Any suggestions as to what might help would be quite welcome.
