[QUOTE="moonbase, post: 1124672, member: 178786"] I'm back :cool: I inserted a Ku-Band polariser in line between the waveguide and the Invacom C120 LNB to have a look at the circular polarity signals from Eutelsat 36B. The polariser was a Swedish Microwave XD12 unit. The experiment was with limited success as I only locked one circular polarity frequency at 12149 L, SR27500 using the IQMonitor tool. In addition, the Promax meter was also able to detect the frequency at reasonable levels. It seems to be the Trikolor mux according to Flysat and Lyngsat? I have attached a few screen shots below of the frequency as recorded in IQMonitor and the Promax meter. Note: - IQMonitor records the signal as H polarity as it does not distinguish between H and L polarities. There seems to be no configuration option for circular polaritiy? Location: Surrey, UK .
