Always had a strange feeling watching that channel, something feels off somehow. Anyway, didnt the video also mention GPS basically has the same capability (to be weaponised)? Seems trivial and logical… its a transmitter.. just transmit noise or spoofed signals. Another thing I see pop up here in the comments is about encryption. Critical infra usually is not encrypted because you need to be able to receive it critical conditions, simple means. These infras have been steadily been replaced by ‘hightech secure’ stuff in the west (like c2000…) but here in Asia i can still get an weather-fax image using a 5 dollar radio.
