QDX sound card question


 

Should I be able to hear sounds from PC applications while WSJT-X is configured for the QDX?? My PC is mute while the QDX is running.? If I change the PC sound card settings from "Digital Audio Interface(3-QDX Transceiver" to my PC's sound card then I hear FT8 signals through the speakers.

Finished assembling my QDX v4 today and made a bunch of FT8 QSOs!


 

You can tell windows to monitor the QDX microphone which directs the sound to some other sound card on the PC.

You need to set up your sound devices, in Windows, so that your default speakers are the ones you want to hear you PC sounds on.? Then, by going into "App volume and device preference" (highlighted in some contrasting color depending on your color scheme in Windows, and found on the Volume Settings page) and then make sure everything is set to your default speakers (the ones you want to hear PC sounds from)? *except* WSJT-X.? You want that app set to play, and listen to/from the QDX.

It's a lot easier to just use the Sound Control Panel.

Thanks for your screenshot Mitch.? Below are my two Sound configurations.? The first screenshot mutes sounds from app, FT8 sounds are silent, but QDX works, it's the one resulting by configuring WSJT-X as the QDX manual shows.? The second screenshot allows both apps and the FT8 sounds to play out loud.? I'm guessing that the QDX does not work.? I did not test it as the FT8 sound is very loud.


 

The new windows sound controls suck.? This is why I say use the Sound Control Panel.? If you widen that window you show, you'll see a link to it on the right side near the top.? Good old fashioned Win7 Sound Control Panel.

Bob,

I don't run windows, but I doubt it can send the input to two different devices successfully.

Well, good. I assume that this is a fairly new ability then as over the years I've heard no end of people trying and finding that to get things to work correctly required the software to have exclusive access to the sound card and system sounds to have their own setup.

It's been around since at least Windows 7, which is ancient now.? I have been listening to my QDX this way in Windows.??

In Linux you have to use pavucontrol to "wire things up" through PulseAudio.? Pulse is a bit of a hog for RPi's though, I have so far declined to install it on mine.

There may be ways to do this using custom config files in alsa, but I'm not an expert there.

Not so.? Use the "Listen" tab in the Sound Control Panel for the QDX device on the "Recording" tab.? You will likely have to do this each time, but it works ok.

You can tell Win to release exclusive control in the same dialogs.

Windows 11 takes 'exclusive control' of QDX Audio (Lenovo ThinkPad) - there is no way to listen to QDX audio!

Mitch,

If I do that on my W10, then turn down the volume to zero it comes back at full volume after a reboot..
It helps sometimes when testing but the waterfall is all I ever use.

I agree re: testing, and that's my primary use for noise as well.? If you operate CW though, it's nice to be able to hear to copy in a set of headphones.? FLDIGI and others don't usually print CW very well, particularly if the op has a "swing" or a "ham fist".?

I suppose, other ways to accomplish this in Windoze include the Virtual Cable drivers such as VB Cable and others?

Fldigi has an audio monitor function designed exactly for listening to the incoming signal and even the output signal if you wish.

Set it up in the fldigi config/soundcard/Device page by enabling it after you have selected the sound output device that you want to listen on, NOT the QDX sound card.


Then go to the fldigi menu and select View/Rx Audio Dialog and the monitor window will popup. Set the settings you wish there.

Windows 11 Sound Control Panel (thinkPad) doesn't have a recorder LISTEN option - Windows has exclusive control of QDX (on my ThinkPad)? - I tried - but the realized I'm dealing with a data-stream BEFORE DAC..
Unfortunately, USB Audio is very difficult to intercept - I'm considering exploring a different DAC solution but if any one can figure a way of listening to the QDX Audio, I'm in!

Turns the QDX into a nice CW rx machine with the adjustable audio filter.? Sweet!


 

Start > Settings > System > Sound > Advanced sound settings . . .

I have identified my sound solution!? After configuring WSJT-X for QDX and connecting it to the PC, the Digital Audio Interface (QDX) becomes the master input and output.? See the attached screenshot.? Apps, like Google Chrome, are set to "Default" which ordinarily works, but not when the QDX sound card is the master.? On my PC, QDX can make QSOs while Google plays through the speaker if Google is switched from "Default" to my local speakers.
