[QUOTE="Vipersan, post: 943170, member: 325666"] Hmm ... I dont think this is so much an overall gain issue ...so much as a IF slope problem .. To me it looks like the gain is very rapidly dumped at the high end 12600 to 12750 so to speak .. The Italian mutistream is in this region.. Nothing else appears to be affected ..but the signal drops dramatically through the switches at the top end ... I need the switches in the system or I can't access the other lnbs and dishes ... I've therefore inserted a Triax in line amp just after the SPS and just before the output of the 16 way diseqc ... It doesn't restore full signal ..but there is a definate improvement ... Insofaras I am getting about 75% or thereabouts indicated on the SX6 .. not zero as I was previously.. The Triax in line amp is different to standard in line amps as it has variable gain and slope pots.. The slope being more relevant in this case .. Some tweaking of these pots for best effect now ..and will see if it gets me a result.. Otherwise I may have to seperate the SX6 from the system and put it on its own dish and LNB. At times like this a good meter like Llews ranger would be a big help.. Perhaps one day after my lottery win .. lol [/QUOTE]
