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.
73,

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.
