[Elecraft] K3: Audio Blast attack

[Wes Stewart]

I had something similar (or perhaps the same) happen to me a few days ago, only I had headphones on.  Likewise I don't remember the exact circumstance.  I do remember getting yelled at by the XYL in the next room, however.  And I was never even in the Navy.
