On some transponders, like ASTRA 19.2E 11817-V-27500, the card can work very well (no lock issues) for hours. On some other transponders, like ASTRA 19.2E 11567-V-22000, the card nearly never manage to get the lock: it's looking like the signal isn't good enough. I turned on the debugging of the stb6000 and stv0288 modules, but I can't see anything wrong. Also, we have noticed that the lock maybe lost by intermittence on others transponders where it may work fine for few hours and then stop working for few hours. After doing some researches about the ALPS BSBE1-D01A frontend, I've found it's the one used in the DREAMBOX DVB-S tuner module (that is running Linux), but I didn't manage to find the source code repository to check their drivers, maybe someone know where is it? Best regards, Sebastien.
