[Elecraft] [KX3] External Key Timing Measurements

[Andrew Moore]

Thanks John - I've been hoping to find some analysis of KX3 CW timing. Do
you know if the on/off delay differences are constant across keying speeds?
Have you looked at timing when using the built-in paddle?

I prefer using the KX3 in its QRP / built-in paddle configuration and don't
expect (or need) K3-like performance and accuracy from it, but I'm curious.
