1.0.0.1:
https://www56.zippyshare.com/v/NywXfOcu/file.htmlBut I do not recommend that, 1.0.0.1 had multiple issues that were fixed in the following releases.
There's no real difference between scanning linear and circular polarization, because both are using 13V/18V to switch polarity, so no reason for not working on latest drivers. Additionally - in most cases circulat LNB's are using one band only, so 22 kHz is not needed, which is simplifying the configuration.
And the most important: LOF Frequency, no matter if 10750 or 11250, is used only for calculation purposes, really card is working between 950 and 2150 MHz (well, even a bit more). So eventual failure for LOF 11250 must be software fault, not driver and not card. So driver changes are clearly a wrong direction.
Try to use CrazyScan with L-band selected and verify with CrazyScan if any signal is coming from a LNB. If any signal will be visible, try to lock and check parameters, so it will be clear what calculation should be done, to go from IF Frequency to real frequency.
