I tried playing around with some of the values in the init-tab, and they do affect the signal levels (signal and snr) reported, but I haven't managed to find something that does give a lock. There is also a if_freq variable in the current driver sources that does not seem to be passed to the chip directly but is used in some computations. In the current driver this value is selected based on channel bandwidth (being only used for dvb-t this far). I've tried with several values for this (8MHz, 0MHz, 4MHz and the currently used 5MHz for 8MHz bandwidth channels). Birr: Do you have any info on this, as you seem to be the last developer working on that demod?
