4.3 is not close enough to 3.8. If you don't know how to set the demod
to 3.8, then we can do some hacks to make it work, but signal reception
is likely to be very poor -- better off looking in his snoop log to see
how the windows driver sets the demod to 3.8
OI have looked sniffs and tested linux driver and found that it is set
to 3800. There is 4300 kHz set in eeprom, it is ok for 8 MHz but not for
6 or 7. Looks like driver needs to do some quirks when this tuner is
used. Anyhow, patch attached is hardcoded to use 3.8 now.
Jarryd, please test. Also some changes to stick plug done, if it does
not work for you can fix it as earlier.
regards
Antti
