[Elecraft] K2 CW speed

[Andrew Moore]

Has anyone been successful in pushing the K2 beyond the 70 WPM external
keying limit for CW operation?  Does it adhere to spec (70 WPM) or
differ in practice?  Anyone try any hardware or firmware mods to bump up
the speed?  I'd love for this great high performance CW rig (or even the
K1 or KX1, despite the QRPish nature of them) to be able to handle up to
100 WPM.
