[Elecraft] WJST and the K3

[Edward R Cole]

Bill, W5WVO gave a very detailed reply.

I would like to say the K3 requires no interface for digital modes. 
Just run two audio patch cords (you can buy then at RS) from the 
speaker and mic jacks on the computer soundcard to the LINE-IN and 
LINE-OUT jacks on the KVX3 panel.  All the audio interfacing is done 
by the K3.  Run a standard serial cable (RS-232) cable from the 
computer to the K3.  In the WSJT sw open OPTIONS under the SETUP tab 
and enter your station info and chose PTT Port 1.  In the K3 change 
your mode to DATA.  That's it!  I leave my mic and compression set 
for voice and adjust audio at the computer.

You will have to adjust audio levels in the computer using the audio 
dialog box (I right-click on the speaker icon at the lower bottom of 
the screen to open this).
Chose OPEN VOLUME CONTROL and PLAYBACK to set transmit levels with 
the WAVE slider control.  Back to WSJT, Click OPEN TEST MESSAGES 
under the SETUP tab.  You will see several windows marked TX1, TX2, 
etc.  Just click one to place the transmitter into TX and adjust the 
slider until you just reach full power out.  You can click the others 
if you are curious but TX1 usually is all that you need for adjusting 
transmit audio.

Click options on the volume window to select PROPERTIES and RECORD to 
gain access to the speaker control to set the level for the 
Spectra-JT display window.
You really should read the WSJT instruction available from the WSJT 
website.  He gives detailed instructions for set up there.

For other soundcard programs follow their instructions for setup.

The K3 is ready to use for digital on the DATA mode and no extra 
interface is needed.  Way to go Elecraft!

OK....  I got the 6 meter bug...as you all know by now....

I have been trying to set up WJST for the K3.  Can anyone send me 
some information as to how to do this?  I am under the impression 
that it needs to be on SSB - but can't find information on which 
sideband.  How do you key the rig on SSB, it does not want to do so 
because I think it wants to see DATA.

I have a SignaLink USB - works great on RTTY and PSK...but seems to 
not want to deal with WJST.  I've RTFM several times but am 
lost.  Anyone can give me a hint...a web page to read (I've read a 
lot of them today)..or something...

I am missing something somewhere.  Who is the expert I can 
communicate off the list!
