Kwaak, I will not apply that until I have done background checking. That driver is used only by AF9015 currently. And I did that driver as reverse-engineering and thus there is some things guessed. I have only 8 MHz wide signal, thus I never tested 7 and 6 MHz. Have no DVB-T modulator either... Maybe some AF9015 user can confirm? Is there any AF9015 & TDA18218 bug reports seen in discussion forums...

regards
Antti
