Very cool story! Methinks it's static, with high enough voltage and
current to create a magnetic field that your radio could pick up. I wonder
that if you tried it with any other radio whether it would still work. I
think not, given the exact circumstances required to make it happen.
There's some fancy terms for it, but they elude me at the moment.
Now I'm wondering if it was the wire to the headphones that was
picking up the sound. Then it wouldn't matter what frequency the radio
was tuned to.
