[Elecraft] K3s Transmit question

[Bob McGraw K4TAX]

Do understand in the K3 & K3S operation the actual output power is 
controlled by the PWR setting on the radio.  The PWR setting on the 
WSJT-X screen is actually audio level.   This should be adjusted about 
mid scale for both TUNE and TRANSMIT. The radio Line Gain will then 
allow you to adjust the udio level such that you have 4 bars solid on 
the ALC  scale.    The 5th bar should be flickering.

73
