[Elecraft] K3 and PSK

[Don Wilhelm]

Robert,

I don't know of any step-by-step instructions, the whole picture is 
complicated because of the variety of computer soundcards that could be 
used.  As far as the K3 is concerned, the procedure is simple - adjust 
the line-in gain setting, much as you would with the mic gain.

Yes, the level can be set using TX TEST - and it is best if you do it 
that way because you don't both other hams with on-the-air signals.

Normally there are two controls to work with - the "LINE" gain setting 
in the K3 and the Line-out soundcard controls on your PC.  The output 
from soundcards vary, so you will just have to manipulate them and see 
what happens.  For starters, I would suggest setting the soundcard 
line-out level at the slider midpoint, then adjust the LINE gain setting 
on the K3.  You should strive for settings that will allow you some 
later adjustment room if possible, but if your soundcard output level is 
very low or very high, that may not be possible.

You want to have a maximum of 4 bars of the ALC meter illuminated.  5 
bars is where the 'real' ALC comes into operation, and the bars below 
the 5th act more like as a 'VU meter'.  You want the level as high as 
possible without actually driving it into the ALC region (5th bar).
