Dave,
I agree with you - there is "something odd going on".
Then, perhaps the power level setting should be renamed to PEP output
instead?
Let us see what Wayne finds out (in due time)
One more early morning on 160 with SSB contest going on it was possible to
work some NA westcoast on CW with an outstanding K3, the diversity really is
amazing!

I checked the calibration at 5 and 50 Watts, the carrier power is close
to the power control setting at other power settings too. Earlier
firmware gives higher power, although still short of the expected 25 -
40 Watt carrier. I have gone back to f/w version 2.46, although that has
useless AM TX audio as there is no compression. I was checking on 80m
into a 50 Ohm load.
I'm not too worried about AM as I rarely use it, but it should be
implemented better than it is.
