"Setting the compression that high really makes a huge difference in average
output "
It makes *some* difference in average output. There is nothing I have been
able to do to get the K3's average output anywhere close to what my Icom 746
Pro would do. The best average power numbers I have seen on my K3 with
various mic and settings combos are about 40-45 watts on specific syllables
or words. Typically I see about 30 watts with normal speaking. I have
tried with the built-in processing, with outboard compression, a combination
of the two, various mics, etc. On my Icom 746 Pro, I see 65 watts AVG with
the same mic and outboard compression. I spent hours doing the tests into
a dummy load, even comparing adding a Yaesu 897D into the mix for comparison
purposes.
The K3 sounds great IMO, but it does not have the same AVG SSB output power
of some other rigs available. That may or may not be important to you, so
decide for yourself how much stock you put in that. There are more details
of my findings here:

Personally, I think it would be interesting to see someone do the same tests
using some better test bench gear. I've sold most of mine...
