[Elecraft] Side Effects of QRQ On The K3

[W5UXH]

I will preface this with the comment that I did not order my K3 until Wayne
did the "QRQ mode" firmware work because I operate a lot of QRQ (the
definition of this varies of course, for me it is 60+ WPM full QSK).

I believe the speed at which someone starts to hear the inconsistency in the
K3 Keying in non-QRQ mode is a function of the individual, and also whether
one is listening in a speaker or headphones.

For me, I just barely start to notice it at 40 wpm with headphones.  At 45
wpm it is intolerable.  At 60 wpm it is unintelligible.  For those who
notice it at 30 wpm, my hat is off to your ears capability to detect timing
variations  

I know a few years ago when testing with others, some thought it was fine at
45 wpm.  

I have no use for RIT or SPLIT, so I am one of the minority who is quite
happy to stay in QRQ mode 100% of the time.  The only time I press RIT is to
demonstrate the QRQ keying to others in non-QRQ mode.  I would like to have
passband SHIFT available, but my guess is that Wayne would find it very
difficult to remove the limitations in QRQ mode, and the target market for
speeds above 40 wpm is extremely tiny.  I had not been aware that anyone
could notice a difference at 30 wpm.  I have what I think are pretty picky
ears so that is interesting to learn.
