[QUOTE="vma, post: 998161, member: 256592"] "Noted: ---- I found that if the "Threshold" setting is seeing the noise floor then this stops the sat ID from responding." Yes. That is exactly how it works! The treshold looks at the average power level multiplied by the user defined percentage, which allows to adjust it. The orange line must clearly intersect the relevant transponders. With bad polarisation configuration, where you see transponders of the opposite polarisation creeping up in the spectrum, you don't want the horizontal treshold line to cross these transponders. I think the satellite identification routine is now free from errors and should be working fine in Ku- and C-band. Thanks for uploading the picture! Regards, Vitor PS: I see you are using the latest version with the big fonts if three decimal places are switched off. :) [/QUOTE]
