One fellow I worked early on with my K3 said it sounded very good, but
he thought the keying was a little "soft". Now, I tend to respect this
guy's opinion, as he is what I consider to be a first class CW op and
homebrewer, but I'm not sure I agree with him on this. He is pretty
"finicky", and may have been overly critical, but I've worked 8 or 10
other K3's so far, and I rather like how they sound.
The K3's keying is a bit softer than most commercial rigs these days,
the rise/fall times being about 5 ms. It is easy to copy at any speed
that I am capable of sending, which is about 45 wpm. I don't think
harder keying would be helpful until above 60 wpm.
The shape of the K3's keying is excellent from the point of view of
transmitted bandwidth (that is, key clicks), something which can NOT be
said of many other radios. The ARRL test reports now include a "worst
case spectral display" of CW emission which shows the results of key
clicks, phase noise, etc., and I imagine that the K3's graph will be
superior to almost anything else out there.
To my ear the CW keying is absolutely perfect, the way I would adjust it
if I could adjust it. I believe that Wayne intends to make it possible
to change the rise/fall times, so the 65+ wpm operators may want to do that!
