Low res old video (~2016) of a GPS spoofing demo in a lab using an SDR. It takes 30 seconds for the Android phone to lock to the fake satellite signals and show a location in China! Uses the open source "GPS-SDR-SIM" repo. DO NOT try this at home. It's illegal.

I found a weird radio signal while monitoring the situation. Apparently since last year, there has been an encrypted (military?) activity on the amateur 40m band, every day! From 7040 to 7070 KHz (I heard them today on 4 different frequencies) Have you guys heard about this?
