I think that we've seen a good deal of news lately about satellite traffic and how there is a good deal of it that is unencrypted
https://www.pcmag.com/news/leak-from-the-sky-it-turns-out-a-lot-of-satellite-data-is-unencrypted
And then there was news of Scott Tilley in British Columbia, Canada who discovered that there were some satellites in a classified network that were sending data in the wrong direction

He has some incredible documentation on what he captured, and how he captured it using fairly common equipment that most geeky-type-folks would have lying around our labs.

I was able to replicate his setup and started capturing data just to see what I could find. I have to say that I was taken aback from the sort of thing that I was able to grab - again - completely unencrypted.

Stupidity inbound.
The sheer audacity of building and selling a radar based on a regenerative receiver-transmitter while also selling it as a 2.4GHz one while actually operating on 3GHz turned out to be irresistible in the long term.
So now there's ten of 'em. -
"Omnispace says .. seeing interference from direct-to-device payloads on recently launched .. Starlink satellites, offering an early test of new Federal Communications Commission regulations ..."
".. company now had “empirical evidence” of increased noise in S-band from Starlink .. that have payloads operating on similar frequencies."
