This is the same person that was listening to a clip from a news helicopter on YouTube and heard some "weird interference" in the audio. She went on from there to do some audio processing and eventually realized it was the chopper transmitting some information. That information was its Latitude & Longitude, after which she plotted its flight path on a map.

Windytan has hearing that puts a bat's to shame.

- icebraining 7y agoOona is great, and her blog is the perfect example why I fid RSS readers indispensable: she posts four or fives times per year at random intervals, yet each post is worth dozens of average articles. The "firehose of information" model is simply not adequate for these cases.
- stevekemp 7y agoI remember when I was a young student I lived next to a park, and I could hear bats! No longer the case, and not for a long time. I've loved this blog though, since coming across it somewhat randomly - looking into decoding the radio-broadcasts that update the Helsinki tram-displays. I never got it to work, despite a few attempts, but it is still something I'd like to come back to. I did get sucked into the world of decoding random 433Mhz transmissions, and doing protocol analysis with ESP8266 devices though. So that if the company sauna gets turned on I can now post to slack..
