[Elecraft] K3 shortened dits - you can remedy this under N1MM+

[Dave Hachadorian]

I have the upgraded synthesizer and still see the shortened dits.

The approximately 6 ms of dit shortening represents 10% of the
dit length at 20 WPM.  It gets progressively worse as the speed
increases (20% at 40 WPM, 30% at 60 WPM, etc.).

Note: this only applies to K3 models that do not have the
upgraded synthesizer.

For an unmodified K3 the solution(s) are:

1) turn on CW QRQ (and lose RIT/XIT/split)
2) Upgrade to the new synthesizer (x2 if sub RX is installed)
3) Use an external WinKeyer with dit compensation at 6 ms.
