The discovery of the signal happened purely by chance.

Tilley regularly monitors satellites from his home in British Columbia as a hobby. He was working on another project when he accidentally triggered a scan of radio frequencies that are normally quiet.

"It was just a clumsy move at the keyboard," he said. "I was resetting some stuff and then all of a sudden I'm looking at the wrong antenna, the wrong band." #military#DOD#NSA#USSPACECOM

There goes 10 years of black budget to a hobbyist accident 😂 https://www.npr.org/2025/10/17/nx-s1-5575254/spacex-starshield-starlink-signal
