[QUOTE="tony smith, post: 1031845, member: 402577"] Hi s-band If your Local Oscillator of your LNB is 17.250Ghz then the IF of your 17.894 signal will be about 644 Mhz the lowest broadcast off Astra 1L K band on H pol would be 1.05 Ghz, so it's not off the bird, I have looked at my site at narrow band down to 1Khz can see nothing like this at my site, it's also outside my LNB pass band filter, (Norsat 18.2 19.2 Ghz dia stab L.O 17.250 Ghz) Surprised that you have no wave guide filters they take the form of small threaded screws along your wave guide, most Vsat feeds normally have them. Look at Astra 1L K band at GMT 13:52 K has ITN K90 at 18.514, plus usual comms carriers, with ITN main Newsnet feed at 18556 ,otherwise she is quiet, and stable [/QUOTE]
