[Elecraft] Setting up FLDIGI on K3s

[Bob McGraw K4TAX]

Within FLDIGI there is a transmit audio level control in the lower right 
corner.    Just below the LK tab.   I use a value of -15.  The arrows 
left and right of the box will increase or decrease the level going to 
the radio.      My Line Gain which is adjusted by using the MIC knob is 
at 30.

There are 3 places where the transmit audio level should be adjusted.

(a)   The computer SPKR level.   {mine is 30%}

(b)   The application transmit audio level   {mine is -15}

(c)   The radio Line Gain level  {mine is 30}

Ideally, they should never be at a maximum or near minimum value but 
more near "mid range".  I call that between 30 and 50 what ever units 
that may be.     This will prevent overdrive and distortion of a stage 
or circuit.  And these should supply adequate level to the radio to 
produce 4 solid bars showing on the ALC scale.   With Elecraft radios, 
always set the transmit power output with the PWR control on the radio 
and NEVER with the audio level.    Also be advised that often when one 
runs another application previously on the computer, the SPKR level many 
change due to the needs or a previously used value.    Just the way some 
things work.   Always check the values to prevent frustration, bad 
signals and "nothing works" conditions.
