Dale, I guess it depends on your perspective. I like 17m, and its phone
band is only 58 kHz wide, with zero margin. The "real" width of the band is
probably more like 52 kHz. Once 100 signals are jammed into that space, and
any time there's propagation, this is the case, it sounds pretty full. And
this is a band where regular contests aren't scheduled.
Depends on where you are and how big your antenna is. If I had a dipole,
the band wouldn't sound as crowded.
'Tis true that when I use my 26 year-old TR-7, which always had a 4 kHz
roofing filter in its first IF by design and from the start, the bands sound
"cleaner" than when I use some much more modern equipment. One reason to
hold on to good stuff, sometimes.

I've tuned around when propagation is pretty good and the bands don't
seem too crowded and that includes 20 m. Seems the only ones who
complain about crowded bands are those that participate in contests.
A sticky point with me is the receiver performance of late model
radios is not so good and that may contribute to what is perceived to
be splatter
The INRAD 4 Khz roofing filter mod for the MKv may help in that area.
I will have mine in about a month. In the meantime, bottom line is
the overdriven amps and excessively wide (20 Khz plus) AM sigs.
