Go to http://www.elecraft.com, then click on "Builder Resources" on the menu
on the left side of the screen.

On the Builder Resources page look under "Main Topics" on the main page and
click on "Application Notes". That will take you to the page with "Elecraft
Application Notes" at the top.

Scroll down on the left side of the main page (with  the white background)
and you will find "K2 Filter Adjustment and Mod Articles". Click on that and
you will find yourself presented with a series of articles on downloading
Spectrogram and using it to align your filters for either CW or SSB.

IF you are setting up your SSB filters too, PLEASE be sure to run an actual
on-air audio quality check, feeding a dummy load and listening to yourself
on an auxiliary receiver (I find it most useful to first tune myself in,
then record the audio so I can listen closely).  If you can't do that at
LEAST have a buddy give you a critical audio check.

Last night I was spooking 40 meters and heard a fellow in QSO on SSB who had
simply awful audio. The guys he was working said it sounded "pinched", which
was a pretty good description. It sounded like his frequency response was
all of perhaps 500 Hz to a bit over 1000 Hz. He explained that he was
running a K2 with a brand new MH-1/Heil mic and "put in all the mods"
Elecraft recommended. Everyone was being very polite but clearly unimpressed
with the sound of his signal.

I have no idea if it was the mic or if he had the filters misaligned.
Considering the reported quality of that mic, I'd suspect the latter.

One thing was for sure- he had NOT checked his own audio "on the air".
