KX3 and WSJT-X Setup

[Aaron K5ATG]

I am having a little trouble here. I have a KX3 that I'm trying to setup
for FT8 using WSJT-X v1.8.0. I'm using a Signalink USB. My operating system
is Linux Mint 18.3
I'm not finding the correct settings for it to work right. I can get it to
decode sometimes. I can get the KX3 to transmit but I really do not think
it is transmitting because when I try WSPR, it does not show me receiving
anyone or anyone receiving my signal. With Windows it was easy, just set
the input and output to CODEC and Applications at 50% and it worked great.
I am having trouble finding the settings for the KX3, Signalink, and WSJT-X
to all work together.

I dont have a KX3 yet (still in the market and saving for one) so I am not
sure if its something KX3 related or not and I am also not sure how you
installed WSJT-X (from the Linux Mint Repo or compiled from source) but
something you can check to make sure it is configured correctly for your
system, as WSJT-X requires 16 bit audio at a 48 kHz sample rate and the
default Pulse Audio setting is normally 44.1 Khz so the easiest way to make
sure this is configured correctly is to copy the file /etc/pulse/daemon.conf
to $HOME/.pulse/daemon.conf and modify the version in your home directory.

Find the line ; default-sample-rate = 44100 toward the end of the file,
delete the leading semicolon and space and then change the value to 48000.
It should now look like this:

default-sample-rate = 48000

Save the file, then reboot the entire system to ensure Pulse Audio restarts
and grabs the updated settings and see if that helps you at all.

I've had WSJT-X working with my KX3 for over two years now. I realize
that you already have the Signallink, but try going directly to the PC
instead and see if that fixes anything.

All you need is:
1.   KXUSB cable for CAT control
2.   Two stereo audio cables for audio in and out.  I bought the KX3
cable kit as it comes with all the cables needed for hookup of the KX3
to most anything.

Turn off any system sounds going to the PC soundcard, and see if that helps.

I use an external SoundBlaster USB soundcard and have never had a
problem with needing any sort of audio isolation.

Aaron,

What you fail to tell is: What hardware does your Linux Mint 18.3 run on?
What I don't know and cannot test is what USB device code is produced by
the SignaLink. Normally a sound card is recognised by the linux kernel
but in some cases it isn't

Try to open a terminal screen (Ctrl-Alt+T) and type: lsusb
That will list the available USB-ports in Linux and any asociated device.

On the other hand: If the PC is a desktop and has both a line in and
headphone out, use these to route audio to and from the KX3. WSJT-X
produces an audio tone that is transmitted as a carrier by the KX3 and
receives an audio tone from it, hence the dial setting and the use of
Upper Sideband.

In Mint, audio in and out can be set by right clicking on the
speaker-icon and choose audio-settings from the drop down menu.

There is no need to set the audio to 48000 Hz in the config.
I have never done this and WSJT-X, to me, works as advertised. Even on
my Raspberry Pi and an external Creative XFi USB soundcard.

Of course YMMV
