An amateur satellite tracker stumbled across the signal which is coming from Starshield satellites in a "hidden" part of the radio spectrum.
It's unclear what the satellite constellation is up to. Starlink, SpaceX's public satellite internet network, operates at much higher frequencies to enable the transmission of broadband data. Starshield, by contrast, is using a much lower frequency range that probably only allows for the…
