[Elecraft] Fldigi Mac no TX Audio

[Don Wilhelm]

Tim,

Do you have *anything* plugged into the LINE IN jack on the K3S?  If so, 
that overrides audio from the internal CODEC.

I don't know Apple, but I do know the K3.  Go to your computer's 
soundcard gain and set the slider for the soundcard output to about 2/3 
of maximum.
THEN - during the Fldigi transmit, set the K3S LINE IN level to produce 
4 bars solid with the 5th bar flickering on the ALC meter.  That is the 
proper drive level.  Note that for the K3/K3S, this is the NO ALC point.
Adjust the desired power with the power knob.  Ignore the internet 
advice to use the audio level to adjust the power - the K3/K3S is 
different than most transceivers in its power control mechanism.

BTW, you can do those transmit adustments with the K3/K3S in TX TEST 
mode so no RF is generated - keep the airways clean of "tuneup signals".

73,
Don W3FPR
