Which begs the question(s), "Why would one engineer a radio that can be
'misadjusted' to create awful signals?" Adjustable keying rise/fall
times comes to mind first I guess since there is one optimal shape and
rise/fall times. All others are sub-optimal. "I want to generate
clicks today so I'll just crank this knob down to 0 and make square
waves today." Harks back to This is Spinal Tap.

Almost any rig can turn from “one of the best” to “one of the worst” if it is
misadjusted.
We as hams should be willing to provide constructive criticism to those with
issues and more importantly be willing to receive constructive criticism.

Just a few comments on dirty signals and the rigs that can, if badly adjusted,
produce them.
I've been using a Kenwood TS-590S for about 10 years. I was asked to give a
couple of digital modes presentations to the local club . I was seeing so many
foul JT65, and now FT8 signals, that I wanted to use my TS-590S to produce bad
signal examples and show the operator errors that caused them. I tried
everything I knew and could not make my TS-590 produce anything but a clean
signal. I had to resort to my library of screen captures of other station's
signals for my presentation.
On the other hand, one of the worst FT8 signals I ever saw was transmitted by a
very experienced local operator using a K3. He fixed the problem as soon as he
saw my screen shots.
Just because someone told you the K3 is the best rig ever made does not mean it
can't produce some really nasty signals!
