I for one would like to have some control over the rise/fall times.
You want the cleanest (narrowest) of CW signals when operating on a crowded
band or in a contest - unless you're a rare DX station. Most of my
operations are 22wpm rag chews on very uncrowded bands. We're often the
only discernible signals on an entire CW band. And conditions are often
noisy with deep QSB. Why not allow those of us operating in those
circumstances to shorten the rise times a bit, which makes it easier to
copy in noisy conditions, when any close-in clicks or thumps aren't going
to bother anybody? Copying a 'soft' weak CW signal is like trying to read a
'crisp' signal that's an entire S-unit weaker, IMO.
My TS-590sg let's me do that, and I love it!
Will the K4 sound as good as a Drake T4C? (Just askin'.)
