[QUOTE="Vipersan, post: 854591, member: 325666"] FWIW .. I've been very closely monitoring the signal level at my location in the firm belief that Saorsat _may_ be a very brief possibility ..at certain times of the day. This is based on the what I now believe to be the scottish beam tansmitting on the same frequency being modulated in 16PSK and that the F15 could never respond recognise and lock this.. So would hopefully reject it. Absolute peak of what I perceive to be the Saorsat signal ...NEVER reaches the magic 3db which equates to roughly 30% ..which I understand to be the minimal lock requirement..according to what I've read elsewhere. Max fringe wobble ..peak signal is 2.6 db (26% ) at exactly 16:47 PM ..and very quickly fades after this time. I honestly believe if I could get say ..another 0.5db at 6:45PM I could achieve a brief lock. Ok ..it would NEVER be a useable signal ..but all I want to do is prove the point. Anyone with an F15 and an inverto Saorsat lnb at the focus of a 1.2 mtr dish either 30 to 50 miles west or 30 to 50 miles South of my location could prove this theory. Previously I had much higher signal levels 5 - 6db plus ..and never achieved lock ..but it's my firm belief that both Saorsat AND the scottish beam were both useing QPSK at this time ....not like now. rgds VS [/QUOTE]
