I've had good to moderate success using the CW decoder. I find several
things to being the key to good results. First, usually the ATTN is
required on lower frequency bands, 160M - 40M, along with correct
adjustment of the RF Gain. Here you want to see that only CW elements
flash the bar on the CWT indicator. Most hams seem to believe more gain
makes for hearing weaker signals. While somewhat true, there's other
factors involved. Secondly, the sensitivity of the CW decoder needs
to be correct for band conditions. I find it does required different
values for different band conditions, usually impacted by noise. I
usually have mine at 3 or 4, never at AUTO. Finally, poorly timed CW
elements will not decode correctly. I do find that near keyboard
quality or keyboard sent CW decodes quite nicely. Of course a static
burst, thus triggering the decoder will produce *** or random
characters. Here AGC PLS value and the value of AGC SLP setting has
a marked effect on results. In general I find the internal decoder to
work equal to or better than many CW software applications I've tried.
None are perfect in my findings.

I too have never been able to get the CW decoder to work well. It only works
if signals are super strong - precisely when I don’t need it.
Anybody have any suggestions?

Perhaps my K3 has a problem, but I've never been able to get the CW decoder to
work very well. (Nor the digital modes.) Fortunately, I've been copying CW
the old-fashioned way for some 50 years, and the K3 otherwise works just fine.

In previous years, I used the K3's decoder and it worked very well. But, for this
contest, I bit the bullet and said, "I'm going to decode the calls myself to improve
my CW." I had a lot of fun doing so, although I had to skip several stations that
were sending above 30 WPM.
A small suggestion to those who know CW. If you are calling CQ and getting no
answers, like late in the contest, consider slowing down so the CW impaired,
like me, have a chance of making the contact. It may improve your score.

Wonderful. I was doing the CQ WW CW contest and a lot of the contest I
worked with a software to help decode the stations. In the last hours of
the contest I decided to configure the decoder of my Elecraft K3s and
started to decode the stations better than with any of the software that is
in the market for this job. Congratulations to Elecraft for this marvel.
