[Elecraft] psk31 & ALC

[Don Wilhelm]

Bill,

Are you using some kind of interface box that has a soundcard built in 
it?  If so, most of those default to mic level output.
You need 20 to 100 times more audio to drive the Line IN on the K3.
Check the documentation for the interface box and re-configure it for 
line level (or high) output.

You must drive the audio input as instructed in the K3 manual, then set 
the power with the power knob.
Following the typical advice on the web and in some interface 
instructions will not work properly with the K3 - I am speaking of the 
often repeated advice to run the rig power full and use the audio level 
to control the power output.  Ignore that for the K2, K3 and KX3 - they 
control the power output differently than most other transceivers.

73,
