Hmmmm! Makes me feel like I knew something when I decided to get the 400 hz
filter instead of the 500 hz filter!
As far as power settings, I usually like to follow a self imposed rule of
never running a transceiver at more than 85% of "maximum". It probably is
meaningless in many cases as far as really being a safety valve, but I
figure that less than maximum strain ought to have some beneficial effect on
the finals, etc. It probably sounds very arbitrary, but I follow this same
rule in lots of things--even other than ham radio. In golf, for instance,
I find that swinging the club at about 80-85% of what might be my maximum
results in better contact and consistency. As far as the receiving station
is concerned, 80 or 85 watts vs. 100 watts should be imperceptible.
Although the K3 may not be one of them, there are lots of rigs out there
that are very closely spec'd, either as to the finals, or the filters, etc.
Some rigs have lots of "cushion"--the older TS-50 comes to mind, which
apparently could easily run 200 watts or more with the finals in that rig.
Some folks were actually cranking them up to that or higher! But nobody
seemed to be too concerned about what the bandpass filters could handle,
etc., and that bothered me enough to resist the temptation. So, I usually
set my K3 at around 85 watts if I'm running QRO. Ignorance is bliss
sometimes!

Interesting review.
Considering IMDDR3 it seems like one should stay
way from the 500 Hz filter, looks like the 400 Hz
is the filter to get.
Also the TX probably shouldn´t be cranked up to
120W but instead 100W should be maximum.
