Once a week or so, my right hearing aid stops giving me audio and starts blasting data into my ear. Like the old dial up modem sounds combined with R2D2. But only at home and only in a few rooms. I figure it’s picking up wifi or Bluetooth and trying to convert them to audio, and failing.
I kind of wish that I had a handheld gizmo -- maybe an ADC that could attach to a cell phone -- that could take into account location and direction and help me locate sources of radio interference.
I have a couple, as well as GNU Radio, but there isn't a software package that I'm aware of that does some analog of something like what Kismet does for WiFi, which will let you move around and use GPS position data to identify the location of sources of radio energy.
I suspect that it'd also be more-effective to do something like have an antenna array and use a device with a common, synchronized clock to identify direction.
