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.
