[Elecraft] K3s Fldigi and Mac

[Don Wilhelm]

Tony,

Be aware that you must have enough audio to fully illuminate 4 bars on 
the ALC meter with the 5th bar flickering.
If you do not have that condition, manipulate the soundcard audio and 
the Line In level on the K3S to obtain that deflection.
Maintain that audio level, and adjust the power with the K3S power 
knob.  This is different than the conventional internet advice which 
says set the power to a high value and adjust the audio to get the 
desired power output - that will not work with the K3S (or the K3 or KX3 
or K2).

If you are using the audio provided by the USB cable, be certain there 
is nothing plugged into the K3S Line In jack.

I cannot provide any more information until you clarify more about your 
cabling setup - specifically, which is connected to what.

73,
Don W3FPR
