Browsing the UHF Satcom Band via SpyServer

Over on YouTube Corrosive has published a video of him browsing through the UHF Satcom band with a remote Airspy SDR being streamed via SpyServer. The UHF-Satcom band is anywhere between 243 - 270 MHz and contains fairly strong signals from many several US satellites that can be received with a simple antenna. Some of the satellites are simple repeaters without security, and pirates from Mexico and South America often hijack the satellite for their own personal use. So it can be quite interesting to look for pirate conversations and sometimes SSTV images. Reception of these satellites is generally available in Canada, US, Mexico, South America, Europe and Africa.

    This might be of interest to people . I live in Pensacola FL. and I can pickup the UHF-Satcom band and listen to the Pirates . I am using A disk cone antenna and a RTL V3 dongle also I use the HDSDR software , I have found that SDR Sharp doesn’t work as well . I have used the Air Spy hf+it gives about one ” s ” unit more amplitude signal .I don’t use anything else .

    Do not think i would transmit thru or interfere with these US miltary sat comms has the gps location adrf will locate you in a matter of seconds ( has a drug cartel in mexico found to there cost last year , when a attack drome paid them a visit! ) Homeland Security dont mess about.

      Nobody suggested transmitting there, however most of the traffic is from pirate users/operators. Imo there is no ‘locating you in seconds’ in the US the FCC would have to RDF the uplink from a local field office and while they may be able to get a general idea based on the transponder you might be illegally using it wouldn’t be pin point exact or even remotely close to GPS accuracy.
