Hi Barry, thanks again, I understood that reply.I got the Fec/Guard values I was using from the Windows XP app display, so am not surprised they are wrong :). Tried your suggestions, but no success. I have googled another user who has had success using a "switched over" transmitter similar to my local transmitter (http://www.dcglug.org.uk/archive/2009/09/msg00538.html), but is not using the same modules as me (saa7146, l64781). I have attached the tuning information from the Windows XP app in case you are interested.
Not knowing what I am talking about - would the l64781 debug output help ?
