[QUOTE="M60, post: 827572, member: 376177"] I thought 1/2 was 50% correction, 50% available symbols? Your right that most use 5/6 for low band and 2/3 in high band, guess though that SES may relax this considering the new birds have higher EiRP levels giving C/N figures much better than previous, certainly the case with the PE beam's for the new birds which will have a much noticeable improvement over 2A and 2B. I suppose at the end of the day SES want to maximise revenue, broadcasters though will want to push FEC as far as possible to maximise available bandwidth, certainly where DVB-S2 is concerned for people like the BBC who are keen to keep distribution costs down. I notice at 13E there's some very high Symbol rates and lower FEC figures, giving something like up to 60MB available baseband bandwidth. [/QUOTE]
