I discovered that my cw power issue was due to a bad power supply for my
Elecraft W1 wattmeter. My cw power measurement now agrees with the K3
setting. I still see a 50% higher power output in Data A mode than the K3
setting -- this is an improvement over the nearly 100% that I was seeing
using previous firmware. These observations agree with what G4ILO is
seeing.
