[Elecraft] K3 Beta firmware rev. 2.82

[David Lankshear]

So, if I'm tuning up through, say, a Z-Match into a doublet and power output 
is set to "around" 5 or 50W and press "Tune" in order to tweak the Z-Match, 
the initial (off-tune) complex impedance the K3 may see could very well 
cause the K3's output power to change to 5 or 50W and because of that, power 
indication would be screwed up without my noticing it?  (Sorry for the long 
sentence, but BTDT.)

Surely, for something that is a calibration feature, it needs to be 
protected by an "on/off  switch"?  It isn't as though this is a new topic. 
I've seen it crop up a number of times in different forms on this reflector 
and have been waiting for the Aptos wizards to make power calibration a menu 
item.  Turn it on in the menu, have a few LED winky-blinkys to warn you're 
in Power Cal., do the job then turn it off in the menu.  I suppose there's 
some horribly technical reason for not doing it.

To normalize the radio's output power for any valid test you
need to measure the single tone carrier power (e.g., CW).  If
you do that (press tune at 50 watts), you will recalibrate.
The recalibration will render any subsequent measurement
incompatible with previous measurements.
