[Elecraft] K3S and WSJT-X

[Bob McGraw K4TAX]

Let me clarify a point.  Use the PWR slider on WSJT-X to adjust the 
number of bars on the ALC indication on the radio.  Do this in 
combination with the {MIC}  Line Gain value on the radio.   You should 
have 4 on solid, 5th flickering.  Actual transmit power is controlled by 
the PWR value as set on the radio.

73
