[QUOTE="Zorba, post: 75089, member: 176203"] I think you are right,Because when i measure with a spectrum analyser i can clearly see the 2D signals(horizontals at least) but the spikes are obviously shorter than the 2B and eurobird.Therefore the signal is present,thats why the signal strength shows something.But when you switch on your digibox you get "no signal" on bbc because the short spikes mean low signal to noise ratio,which has to be over a certain figure for the picture to appear.So when you get one "notch" on your signal quality,the picture is on the treshold and probably pixellating,like sky movies in the afternoon on a 2.4m dish in larnaca. The other factor is that the symbol and fec rates(22000-5/6)on all channels on 2D are different from 2B etc (27500-2/3) which is like a higher threshold for the digibox to deal with. Thats only my theory though. Sorry,Geoffreys,but it looks like its a 3.8/4.2 for you. Or move to Paphos(nice this time of year) :) [/QUOTE]
