I previously said "Here is a link to a youtube recording of what I hear on
136 MHZ AM using a small handheld scanner (Radio Shack Pro-94)"

By the way if you look at the audio waveform of the noise in this recording
using a soundcard based scope (or a stand along oscilloscope) you will
easily see that the noise spikes are at 120 hertz (arcing each half of the
sinewave).
