[Elecraft] K3 - Maximum CW speed from manual key

[Bill Frantz]

To try to make sense of this experiment, I immediately assumed 
that Kurt wouldn't be using a hand key, but rather a device that 
interfaced to the radio through the KEY jack. Obviously an 
electronic switch could switch the key jack that fast, but I'm 
not sure about a relay.

The other question that occurs to me is, "How wide will the 
resulting signal be?"
