Quick summary:
> Many navigational and meteorological satellites carry a search and rescue (SAR) repeater which is intended to receive UHF emergency locator beacons and rebroadcast them in the L-band or higher. However the repeaters appear to be picking up all sorts of other signals from the ground, including voice transmissions.
- actionfromafar 3y agoMakes me wonder if these ever were used out-of-spec for transmission deliberately by parties. (Thinking spy stuff but it could also be just hijinx.)

- IshKebab 3y agoThe article suggests pirates which makes some sense.
- wildzzz 3y agoUnless someone has proof otherwise, I'd bet that they've never been used for that purpose. Every major government is listening to this SARSAT downlink so it's probably better to use something less visible.
- actionfromafar 3y agoNumber stations are also a thing.
- joshspankit 3y agoAs mentioned in the video; that would be inadvisable. Not only is it illegal and constantly monitored, but it’s almost trivial to triangulate the source of the transmissions. You could probably get away with sending a couple messages while pretending to be someone doing it accidentally, but you’d be holding up a “pick me” sign visible to any type of scrutiny.
