I have been watching a show about paranormal activity on the History Channel called the Secret of Skinwalker Ranch. On the episode this week they hired a professor to do a balloon launch with some RF sensors. In the episode they showed the APRS.FI webpage and I was able to read his callsign from an APRS tracker, KM4MRH-3. https://aprs.fi/#!mt=roadmap&z=11&call=a%2FKM4MRH-3&timerange=3600&tail=3600

Sadly they are using these for measuring RF fields
