I know of no amateur transceiver that uses the same approach to power
setting as Elecraft but it is common in commercial transmitters.

John,
Other transceivers normally control the drive with a potentiometer that
adjusts the gain of one of the transmit stages.
The K2 and K3 do it differently - they actually measure the power output
and compare that to the power level that you have requested. The
microprocessor then adjusts the
ut it is too sensitive at
high power settings.

Why would you want to "avoid" level control in the transmitter? What issue
do you avoid by doing that? 73, Guy.

All (especially Don),
I have heard it explained on this reflector the Elecraft power control
loop is such that the usual advice to...
"max out the power setting and adjust the audio level input to avoid
AGC action"
...is not appropriate for the K2 and, I suppose, the K3.
I accept this, but
