[QUOTE="NoviceSat, post: 811155, member: 390074"] I decided to get "another toy" and ordered a TBS 5925 - which has now arrived. So I plugged it in and scanned 9.0E and got absolutely nothing! (Actually that's missing out a lot of hassle trying to get the USB drivers and software to actually work - "professional" might apply to the price and the feature list, but not to the quality of the (Windows-based) software!) I have managed to get CrazyScan to work with it (again after several failed attempts), here is what I get with my standard Ku LNB with my 80cm mesh dish. The weather was overcast with the odd sunny spell. It is on a tripod and I've just "spun it round" and done a quick alignment with a SatMeter. It's probably not 100% on target. Also (note from another thread of mine) that the dish might not be 100% aligned... [ATTACH]51117.IPB[/ATTACH] My channel of choice for 9.0E is "Duna" (because it is strong and has V polarization) at 11.766GHz - it is perfectly watchable with no break-up. This would appear to have a RF level of -47dBm. Now I put the Ka LNB in its place, and try a bit harder with the SatMeter (it is not possible for me to swap LNBs without knocking the satellite out of alignment - I don't have everything tightened-up). I obtained no channels at 10765V 25000 1/2 QPSK. So running CrazyScan again (the later versions support Inverto Ka LNB directly now :)), I see this: [ATTACH]51116.IPB[/ATTACH] Novice questions now: I guess the "fat" humps are data channels? It would appear my mesh dish is not very good at around 20GHz+ (you were right zg3409), but more importantly there doesn't look to be much for me at 20185L. I'm confused why CrazySat says Vertical/Right and Horizontal/Left, when I'm supposed to use 10765 V on my receiver (that would imply L=V?) Has anybody got a TBS to lock onto Ka channels? It appears as a strength of "60", but will not lock. [/QUOTE]
