I am hoping that the K4, like its predecessor the K3(S), does _NOT_ give
a user the ability to change its CW rise times.
I believe the K3 is designed for a 5ms rise. Many, if not most, other
manufacturers allow as little as 1ms resulting in CW signals that reach
beyond 1kHz of bandwidth by creating horrible key-clicks. Indeed, their
"default" values can be too short. To what end? Unscrupulous users
setting it so their clicks help keep their run frequency clear?
Terrible to think that but I have heard some station owners admitting same.
Last weekend's CWSS had many, many horrible key-click stations - some
from notable contesters. I realize that things other than a CW rise
time can give cause to key-clicks (antenna connections, hot-switching,
etc.), but newer radios shouldn't be the culprit - yet they can be
because of manufacturer's oversight (or under-thought).
I've never heard of a short CW rise time being an advantage other than
to create havoc. There is a happy medium.
