[QUOTE="s-band, post: 1151623, member: 407744"] [USER=412221]@dreamsat[/USER] Yes. It does appear to be at 49E although the 1.2m is not as accurate as dreamsat's 2.2. It is to the east of Syracuse 3a & 4a and stable so not likely to be Orion 10. I was using the 8.4G front end which is not ideal at 7.5G. There is a 50MHz wide signal as well as the group at 7495. The cluster below the main one is from Syracuse 3A, I think. [ATTACH alt="49E_SA_PNG_000623.PNG"]151737[/ATTACH] Looking closer, there is a band of transponder noise about 16MHz wide with the signals seen in the middle. [ATTACH alt="49E_7496_20MHz_Span.PNG"]151736[/ATTACH] They all look like BPSK, some have discontinuous modulation e.g. [ATTACH alt="49E_7495MHz-1.PNG"]151739[/ATTACH] Some are continuous and there are a few different data rates. [ATTACH alt="49E_7495MHz-2.PNG"]151738[/ATTACH] (Waterfalls: 21.4MHz = 7495MHz) I haven't a clue which satellite it is though. If someone can drive the ITU database, it may be identified. [/QUOTE]
