Mystery signal from a helicopter

This is one of the coolest/geekiest things I’ve ever seen.

After hearing digital interference in a YouTube video from a helicopter police chase, this hacker was able to figure out the helicopter’s flight path on Google Earth.

Here’s how she did it. Total badass.

Read the rest of her blog for some fun hacking adventures. This particular passage had me particularly entertained. While she was waiting to get some takeout food, the server handed her one of those papers that vibrates when your table is ready.

For this kind of situations I often carry my RTL2832U-based television receiver dongle with me (the so-called rtl-sdr). Luckily this was one of those days! I couldn’t help but tune in to 450.2500 MHz and see what’s going on there.

Gangster.
