K3 Audio from RS232 connection?

Bob KD7YZ
So today I was reaching behind the K3. The board connector that Is/Was
the USB input, came out in my hand.

It came off the KiO3b board.

I was reading the paper that came with the KIO3b install and discovered
I can use the RJ-45. Which I did.

I currently am controlling the K3 with DxLab's 'Commander'. So the RS232
connection is fine.

When I ran up WSJT-X and was attempting to connect, I noticed No Audio.

The 'Commander' IS controlling the K3 and quite well. Just can't do FT8
or MSK144 Meteor-Scatter anymore.


How do I get digital audio? I gather it's NOT thru the KIO3b RJ-45 .
That flimsy connector was SMA soldered and that level I can't do .. or
wouldn't try anyway. Skill level deteriorated for that small stuff.


Any help on the audio?

You can use the line in/out connectors in the back of the radio
and a "sound card" for your computer. USB sound cards are
available inexpensively from Amazon. I have one for my KX3 which
I think cost about $5.00. You may need to install a pad to lower
the signal level between the line out on the radio and the Mic
in on the sound card.

In an ideal world, you will get the the RJ-45 connector
repaired, either locally with someone who can re-solder the
surface mount connector or by getting it repaired by Elecraft.

If the USB cable is disconnected from the K3S, the USB Sound Card (USB
Audio CODEC) will no longer be available.

You have to switch WJST-X to use the sound card in your PC.  And you
have to run two cables:

K3S LINE OUT to PC LINE IN (or MIC)
K3S LINE IN to PC LINE OUT (or SPKR/Headphones)

Adjust levels using the Windows level controls and CONFIG:LIN OUT and the
MIC GAIN knob (which adjust LINE IN level when MAIN:MIC SEL is set to LINE).
