important, not the absolute timing of the rise of fall time.
In other words, the transitions of the waveshape are the important

On the Ten Tec Eagle list, Rob Sherwood just posted a very interesting
response to the 2 kHz DR rankings being discussed here. Apparently, there's
a measurable amount of IMD difference not only between roofing filter
production samples, but the manner in which they're inserted. For example,
The K3 sounds very good as a SSB rig. Apart from a few digital modes,
that's almost all I use it for. You have almost complete adjustment of your
TX audio by adjusting 8 band EQ, compression, and noise gate. If you hear
one that sounds bad, it's more than likely a setup issue by the operator.
Last night I was setting up for ARRL 160 and had the K3 in full QSK mode.
During a QSO I had I noticed during TX a randomly occuring crackling noise
followed by a one second or so muting of the monitor audio. In semi-QSK
the problem disappeared. Is this due to a too-short delay setting? I've
