[Elecraft] K3 Mic Gain vs ALC

[Paul Christensen]

> Not only SSB. I have overshoot on CW.

This problem appears to be rig-specific.  I just duplicated his test using 
three wattmeters in series, together with a Bird 4273 RF sample.  The sample 
feeds a Tektronix SC504 oscilloscope.  My wattmeters are the Alpha 4510, 
LP-100, and Array PowerMaster.  With the K3 set to 22 watts from the menu, 
keyer to 30 WPM, I then sent a single "dit" on 40M CW into a 50-ohm Bird 
TermaLine load.

Observation:  I waited 30 seconds for the ALC to stabilize between each 
successive "dit."  All three wattmeters read between 22-23 watts in peak 
mode.  The oscilloscope showed no overshoot whatsoever.  I have no mic to 
plug into the K3 at the moment, so no SSB overshoot testing was performed.
