[Elecraft] K3: Still unable to set power correctly in DATA A (sigh)

[Stephen Prior]

I can report the identical problem to that which Julian describes.  I don't
remember the firmware version where this started but it was certainly not
always the case that the actual power output in Data A mode was so much
greater than the requested power.  I can set for 5W and get a displayed (K3
meter) output in excess of 10W. No problems at all with the other modes that
I have tried.
