All right, all right. I was getting my frequencies from the table that came with the Windows TT drivers. Which also matches the centre frequencies of the 'well-known' channel assignments. Like on the last page of this document: http://www.aba.gov.au/broadcasters/pdfrtf/geninfo.pdf Although the same pdf does say that specific implementations of DVB-T can use +/- 125kHz either side of the centre frequency :) I have no idea how I'd go about modifying the TDA10045H driver to use a different step size. As far as I can see, 167kHz is the resolution of the current calculation (1MHz/6) ... so I'd have to actually understand how those registers and the values written into them work... which I don't 8) {P^/ > Regards, > -- > Robert Schlabbach > e-mail: [EMAIL PROTECTED] > Berlin, Germany > > > > -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
