Hi, my friend told me that he is sometimes able to get lock by decreasing (not increasing) the frequency. Yesterday I've tested it and it seems to me he was right. So I'm able to get (not very stable, for few minutes) lock as well as by increasing and by decreasing frequency of the same channel (EurosportHD). It was also detected (not by me, I don't have riser card) that when the card is connected not directly into PCI slot but with some riser card, the needed difference for getting lock is higher (up to 10MHz). So also some noise from PC is going into calculations. I don't think the problem is in computation of frequency but in for example not stable signal amplitude at input of demodulator or in not fluently changing the gain and bandwith of tuner within the band. As I see in the code some parameters are changing in steps and maybe 3 steps for whole band is not enough? Especially in real conditions (not in lab)? But under Windows no problems were detected, so it seems that all that problems are solveable by driver (software).
