[Elecraft] K3S and WSPR

Benny,

The settings for WSPR are no different than any other soundcard data 
mode, so the setup is the same even though the soundcard is internal to 
the K3S.

Set the K3S for DATA A and the MIC SEL to LINE.  Make sure nothing is 
plugged into the LINE IN jack in the rear because it will switch out the 
output of the internal soundcard.

The internal soundcard setup is just like any other USB soundcard.  Tell 
your application which soundcard to use and set the output (speaker) of 
that soundcard to about 75%.

Then tell the application to transmit - with the K3S, you can use TX 
TEST mode or connect a dummy load so you do not transmit RF.
Adjust the MIC GAIN (now LINE IN gain) to produce 4 bars solid on the 
ALC meter with the 5th bar flashing.

Adjust the desired power with the K3S POWER knob.
Yes, this is different than the common internet advice, but the K3(S) is 
different than other amateur transceivers.  Use the information in the 
K3(S) manual when setting up soundcard data modes.

73,
Don W3FPR
