[Elecraft] When is mode A not mode A?

This discussion emphasizes the oft-repeated point that the built-in
keyer firmware (shared by the K3, K3S and KX3) is really rather basic,
lacking many CW features that are present in a $6 Winkeyer chip for
example. 

And before someone says "So get a Winkeyer already!" please remember
these three points:

1. Portability and excellent CW operation have always been prime feature
of the Elecraft range... but both of those claims falter if significant
numbers of owners are forced to use external accessories. 

2. Elecraft transceivers are uniquely dependent on the built-in keyer,
which MUST be used when sending RTTY and PSK31 from the paddle.

3. We're all "wired" differently as regards high-speed fine motor skills
- meaning that each one of us is somewhere along a very broad spectrum.
Nobody is qualified to judge whether the built-in keyers are adequate
through their own experience alone.
