Kristinn,
If you have properly calibrated the wattmeter (balanced it according to
the manual and made the R1 adjustment with respect to a known good power
meter), then yes the peak power developed by the K2 should be equal to
the power setting. The accuracy is only as good as the external meter
used when calibration the KAT2.

Thanks, everyone. I am still working on the presumption that 5W output for
CW and 10W PEP output for SSB would be acceptable for my purposes of award
gathering and contesting, as I already pointed out in my initial post. I
justify this even further with the fact that my antennas are mediocre at
best, typically random wires or a temporary dipole at best.
But my question was specifically on the K2 and how it controls its output
power. So, again, I presume the K2/KAT2 power regulating circuitry
guarantees that:
- if I set my power level at 5W my CW key-down output power will actually be
5W
- if I set my power level at 10W my SSB PEP output power will actually be
10W (avg power somewhat less)
...or relatively close to this. Right?

Subject: Re: [Elecraft] K2 power setting for SSB QRP?
Most QRP contests have a QRP limit of 5 watts for both CW and SSB. I
know
the ARRL does that. ARCI, and I think GQRP, had QRP on SSB limited to 10
watts, I think in an attempt to account for the disparity between the two
modes
QRP-ARCI defines QRP as:
QRP operation for QRP-ARCI purposes is defined as operation with a
transmitter power output of 5 watts or less (CW)(A1) and 10 watts PEP or
less (SSB)(A3J). QRP-ARCI awards are based on these output levels.
.
I believe most other QRP organizations agree with this, although there are
some groups / contests that specify that SSB QRP is 5 watts (or less)
output
on all modes. As far as I know, no one uses the well discussed (and
sometimes over discussed!) use of ERP in QRP power levels.
