I had the fortunate experience to work Jim during the contest and yes he had
a nice clean signal.
With the settings on my K3, Heil IC mic and SGC power cube I had multiple
comments on my signal and how nice it sounded. It felt good to have busy
contesters make such a statement.
Right before the contest I adjusted my compression to 10db per meter on the
K3 front panel and I have a 2.7 filter installed.

I'm glad K9YC answered your question. If you heard Jim's signal during the
SS this weekend then you got to hear what the shaping he is describing
sounded like. His audio was very piercing but clean. It's not what I would
want to hear during a long ragchew with him, but his purpose was to project
his intelligibility across 40 meters for the purpose of a 30-second contact.
Another way to look at this is that our ear is most sensitive to frequencies
around 2 kHz (roughly) and so you really want to put as much of your power
in that region as you can. In this way, you're using the response of the
other op's ear to your advantage.
To further paraphrase what Jim said, when it comes to compression, "A little
is good, but more is not better," as evidenced by so many shockingly bad
signals this weekend. I wish someone would undertake a project to send
contesters recordings of themselves. I happened to be listening when a
station with especially egregious audio called K9YC, who gave the op a quick
but honest report at the end of his exchange. Who knows if that station will
heed the advice for the next contest.
