[QUOTE="s-band, post: 1151302, member: 407744"] Here are my observations of things that might be included, there are very few TV related but some, e.g. meteo, produce images: UHF - Pirates on milsats, mainly in S America and Iberia around 200-300MHz also some around the search and rescue band around 405MHz. Turkmenistan SECAM TV has been seen coming through Meridian 9 at around 990MHz L band - Inmarsat Aero around 1545MHz [ATTACH]151575[/ATTACH] Meteo around 1.7GHz S-Band 2.2-2.3GHz - In 2021 Space X video was decoded but that game was over when they encrypted it - Geo/MEO/LEO beacons and narrow data - DSN but most too weak - DSN Example: Chandrayaan 2 Lunar Orbiter [ATTACH]151576[/ATTACH] 2.5-2.7GHz - Way back in 1990ish, Saudi Ch2 on Arabsat [ATTACH]151577[/ATTACH] - If you happen to be far enough East there's some TV on SES7 108.2E - If you're far enough west you might get Sirius XM radio X band - Quite a lot Below 7.25GHz DSN uplinks if they bounce off something, here's the Chang'e 5 uplink via the Moon. [ATTACH]151578[/ATTACH] 7.25-7.75 Milsat and some Meteo. There was one reported test of TV on Astra 28.2E but that's all I know of. - Example of GS & Data on WGS9 [ATTACH]151579[/ATTACH] - Lots of other weird things - TT&C Beacons 7.75-8.4 Earth Observation - This where most of the better meteo pics can be received although I've not done that - Here's Cosmo Skymed 1 a LEO with SAR (Synthetic Aperture Radar). The downlink is more than 200MHz wide it can be seenat the low end of this plot with the SAR at 9.6GHz. [ATTACH]151583[/ATTACH] 8.4-8.5GHz Busy DSN band - Some things have been decoded e.g. Tianwen 1 - STEREO-A is easily received at the moment as it is close at around (9Mkm) Here's a 195nm pic from it: [ATTACH]151582[/ATTACH] - Here's some DX, Juno at just under 900Mkm [ATTACH]151581[/ATTACH] With the exception of Arabsat S Band (3m Winegard dish) and Inmarsat Aero (Helical antenna) all examples were on a 1.2m dish. Higher bands to follow..... [/QUOTE]
