I do wonder, considering the FEC is currently 5/6 on all the ex-2D TP's, whether broadcasters will take the opportunity to lower this to 7/8 or even 1/1 (ie non), considering the C/N level across the UK has increased by about 5dB. Obviously the only thing they'll be worried about is rain-fade margin but if it takes it down to 2D's fade-margin then they'll live with it for the increased bandwidth. Potentially there's another 8M Symbols available, broadcasters like C5 would appreciate that for improvements to PQ on their congested transponder, also C4 could fit 4Seven along with the other SD C4's.
Obviously this has effects for those on the fringes and expats too as you'd need a much higher C/N figure to get lock.
