Don thanks so much for your quick reply and help.

If you have not already, check out the K2 Dial Calibration article on my
website. Part 3 covers the filters.
If you need a copy of Spectrogram, look for a link near the bottom of my
home page.

The K3 power calibration is done at CW (key down) but FSK includes a
bit of shaping to reduce key clicks. That adds just a bit of peak
to average power difference and would account for a small difference
between CW and FSK. I measure just under 1 watt difference at 80 W
between CW and FSK

What lingers is the high end hiss that I and a few others hear. Apparently this

My newly-built KAT100-1 has been working FB very impressed.
However, tuning up into a 50-ohm dummyload I get a 1.2 swr reading on 40 meters
while perfect readings from 160 to 10 meters!! This doesn't seem right, I
rechecked the dummyload into a different rig and my ICOM 746pro shows .1.0
Eddy,
I would not advocate doing anything. The KAT100 firmware quits tuning
when it determines that the SWR is low enough, and less than 1.5 is
generally deemed low enough.
The next time you do a TUNE into a dummy load on 40 meters, it may (or
may not) be lower.
There are stray inductances
Upon further reading, the corrections of this module appear to be in ~1Hz

The audio LPF that was added to the DSP board has a cutoff frequency

That could be what it is. The hissy sound that some folks are hearing is
probably simply a passband that's unusually flat. Those interested should
familiarize themselves with the plots on Barry N1EU's page:

The K3 is not like other rigs which tell you to adjust the audio level
