Hank,
My initial guess is that it is your Powermaster.
I have recently built a 4 State QRP QRPometer to use when testing QRP
transmitters. It is an accurate meter as long as the waveform is a good
sine wave (Good CW signal), but I have also discovered that it does not
read correctly if the waveform is other than a clean CW signal (like
PSK31 or RTTY). The cause is the detection methods used in the meter.
I cannot say that your Powermaster is doing the same thing, but I will
venture a guess that it is related.
The K3 does a very good job of controlling power at the requested level,
no matter what the mode.
But then your question is valid - I don't know your particular answer,
and I do not have a Powermaster meter to test with. I am only offering
my suspicion.

If I set power to 100 watts on CW the K3 setting and my Array Solutions
Powermaster power meter read the same within a watt or two. Leaving the K3
power set at 100 watts on CW and switch to DATA and run MMTTY diddles , the
Powermaster is reading 116 watts. Sending RTTY text it bounces between 115 and
105 watts or so.
K3 SN 7536 latest non beta firmware.
Powermaster or something in K3 ??? This is not Powermaster II and I have two
couplers , both do the same. SN2441 box.
