While portable voice recorders fall under Paragraph B, there is a
report of an iPod causing interference in the cockpit:

There's only one thing left to try...
I turn off my iPod that's plugged into the headset (not "Ride of
the Valkyries", but Amy LaVere)... silence. Wow. Cool. Plug back
in, "podunk..."

Somehow the combination of iPod, wire and LightSpeed 30-3G was
acting as a radio (a very crisp, loud radio) picking up multiple
frequencies at once. I wish I had written down all the airport
names so I could see how many I was hearing, but it was quite the
cacophony. I called LightSpeed and the guy there had never had
that reported before.



This is hardly at issue. The iPod was wired into the pilots headset.
