The K3s is one of several 1.8 to 54MHz transceivers that has suffered the

I don't have a TS-590S but I'm sure somebody who has one can tell you
how. Crank up the audio drive from Windows (or whatever), run the
TS-590S in USB mode and crank up the audio gain and compression, etc.
It simply doesn't make sense that you can't overdrive a TS-590S.

Of course a K3 can generate bad FT8 signals if you drive the audio hard
enough, but I guarantee that it can be easily done with a TS-590S as
well. You just didn't do it right.

Just a few comments on dirty signals and the rigs that can, if badly adjusted,
produce them.

Yes, as I understood it, the Icom rise time default is a BAD choice, but recent
(e.g. IC7300 and others) radios permitted changing this to a better value,
although still behind the cleaner output of Elecraft & Kenwood.
The other interesting part of the discussion was the use of “pre

I just extracted that period from my log (DXBase) to take another look after all
of these years. I operated only 20-meter SSB and took a break from 0718Z to
1347Z. There were a lot of two QSO/minutes and some three QSOs/min. So it's
more like 88 Qs/hr :-)
This predates my K3, so
there IS a 100 W category. 500 W max for high power (this year). last

I suspect that after the software becomes more stable, and more folks
use the K4, it will replace the K3 for DX operations... The question

used two sets of batteries.
The maximum output was 1.5 watts but after 2.5 hours of operating power output
dropped to .5 watts. So, I used another set of fresh batteries to operate a
