[QUOTE="s-band, post: 967846, member: 407744"] That may be the beacon, it looks similar. The beacon is quite strong here relative to the aero signals. I can't see anything that looks like your 2nd pic. Attached are pics of the beacon (I think) and the Aero sigs. The T channels are at the markers and there are some R channels around 1526.3MHz. The effective sample rate is 1.25Ms/s & FFT setting is 131072. You could replicate the settings to get an idea of relative s/n in a known bandwidth. I think you can set 1Mbps? I realised why the s/n I get on 25E is worse than 15w - I'm looking through trees that weren't that big 20 years ago when the dish was installed - doh! I'm getting about 4-5dB xs noise. The Aero s/n is 2-5dB which ties in with the 6-13dB on 15W [ATTACH]92254[/ATTACH] [ATTACH]92255[/ATTACH] [/QUOTE]
