Raspberry Pi, K2 and WSJT-X questions

Has anyone figured out how to control a K2 from RPi running WSJT-X (or FLDIGI,etc.)?

Also, has anyone been able to run a digital program using a USB soundcard? I have a Star Tech 7.1 connected to my RPi. At the moment I am trying to get it to work with WSJT-X.

I am running Debian Jessie.

The sound card is recognized by the OS. When I run WSJT-X and select the Audio tab and select the Input drop down, there is a list of 22 sound cards none of which is the USB card. A similar issue exists on the Output selection. I don’t understand what I am seeing. How do I get to see the USB card in WSJT-X?

Note that I have made forum postings on WSPRnet and RPi ham Yahoo groups without yet getting a solution.

I hope someone can help with this very frustrating situation. Also note that this is my first experience with a RPi and my Linux knowledge is limited.

73,
Jim WA4YWM

Re: Raspberry Pi, K2 and WSJT-X questions

While I run WSJT-X for JT-65 and JT-9, I use the radio to computer USB
cable for communications and audio. Of course I'm running Windows 10.
Everything works great and very simple to set up and operate.

While your preference is Linux, seems you are making the issue much more
complex than necessary. I can't assist with any of the applications you
reference.

The soundcard you're looking for may appear under a different name.

Try looking in WSJT-X File->Settings->Audio for one that begins
"alsa_input.usb" for the WSJT-X input device, and "alsa_output.usb" for
the WSJT-X output device.

The command 'lsusb' will show you information about USB devices recognized
by Linux running on the Pi. Run it before and again after you plug in your
USB soundcard. You should see a new entry after you plug in the sound card.

To determine what device to use in the program you are using for WSJT-X look
at the end of the file /var/log/messagses (or try the dmesg command) to see
if a device node was associated with the USB soundcard. The audio device
will wind up taking the form of /dev/something, where the "something" you
will have to determine from the system log file.

The above information is general Linux based suggestions that might help you
determine what entry you need in the WSJT program.

Re: Raspberry Pi, K2 and WSJT-X questions

In reply to this post by Richard Lamont

@Richard (G4DYA)...I also initially selected the Alsa settings in the
WSJT-X drop-downs. I found that this sound card setting had quirks. The
setting worked, but would always reset the mic setting. I experimented,
because I didn't like having to set the mic setting in the OS sound
settings every time I used WSJT-X. I found a value in the soundcards list
called Sysdefault for the USB sound card I had connected to the RPi. This
one worked the way I expected...no more resetting the mic volume to max,
but instead respecting the setting that was there. Now I can move among
different digital programs (FLdigi, WSJT-X, etc.) without having to change
the mic setting in the Linux's sound settings.

I am running the latest version of Raspbian on an RPI3.

regards,
Brian

Replies on-list, please. I'm also interested in the answer, and I'm
sure there are others.

Re: Raspberry Pi, K2 and WSJT-X questions

Hi Jim,

I can’t give any suggestions / answers regarding the K2 part of the question, but…. I run a KX3 connected to my Raspberry Pi 3 and operate WSJT-X JT65, JT9, and MSK144. Also use FLDIGI, but very, very seldom. I use a Tascam external USB sound card: the US125M model. With WXJT-X up and running, if I select the Preferences->Audio tab, here is what I have:

Input: sysdefault: CARD=CODEC Left
Output: sysdefault: CARD=CODEC Mono

And yes, there a bunch of devices listed in that drop-down, but the above works just fine for me.

I’m running Raspian Jessie for the OS, and my WSJT-X is a development version: 1.7.1 r7557

Hope that helps on the audio side.

Re: Raspberry Pi, K2 and WSJT-X questions

I cannot help with the Raspberry Pi nor the soundcard, but once you get
that straightened out, I can tell you how to set the transmit soundcard
audio level for the K2.

We have heard a lot about the K3/K3S, KX3 and KX2 requiring 4 bars with
the 5th flickering on Transmit audio - this is the No ALC point for
those radios.

The K2 is the same, but the ALC display in the LED Bargraph of the K2 is
different. Any ALC bars indicate ALC action. So the answer is to
advance the audio until you see an ALC indication, and then back off a
bit until it disappears.

Once the audio level is set, the advice for all the Elecraft gear is the
same, leave the audio level alone and adjust the power output with the
POWER knob.

You may want to check on Jim Brown's K9YC advice for properly bonding
computer, soundcard and transceiver. If not, you may need to use an
interface box to eliminate hum, buzz, and noise (but Jim's advice is
better if you implement the whole solution.
