This is the band sweep of 80M on my QDX. I'm wondering if this is normal:

Yes, it's actually quite good for 80M. Better than mine.

Awesome. Thanks for the response. I ran RF filter sweeps on all of the bands to see if maybe something was wrong with my LPFs (assuming that's what this tests). All part of my still troubleshooting my audio problem.

I've been following the thread on your audio issue. Very strange as obviously the sound card is working and Windows sees it. I'm not a Windows guy, just have a test setup with Win10. Anyway I'm waiting to see what the solution is. I'm sure there is one.

Thanks. I'm sure there is one, as well. I'd say this is causing me to pull my hair out, but I'm already bald...HIHI. I may try running this on a pi to see if I get better results.

My main ham system is a Pi-400. Works great and no funny issues like Windows.

Wayne.

It tests the BPFs. Unless your LPFs are very bad they will make no noticeable difference.

Wayne,

I have a different radio set up with Windows 10, but I know that the OS sound settings can be very squirrelly.? Look for "Sound" app.? When you plug in your QDX you should be able to see the sound card appear and disappear when you plug in and unplug the QDX.? I would not use any external sound card since the QDX has a built-in sound card. To open the Sound app is slightly obscure.? Search "Control Panel" in the search box.? Go to "Hardware and Sound", then click on "Sound".? This should then have a list of sound devices on the computer. You should see the sound card appear in both "Playback" and "Recording".? The "Recording" side shows your receive audio and there is a bar graph on the right of the app that shows the level.? For my FDM-DUO, this level shows at about 50% to get a good level on WSJTX.? Transmit is shown under the "Playback" tab.? Under "Properties" in the lower right it opens a new pane that has "levels" if you need to adjust output.? When the radio is transmitting, you should see the bar graph under Playback and the appropriate device showing a level.?? I make my radio device "Default" for Playback and Recording, and I generally disable the other stuff, such as built-in mics and speakers, for testing purposes.? Windows is very finicky with sound configuration in my experience.?? Seeing the level on "Playback" doesn't necessarily mean the radio is putting anything out.? It just means Windows is creating a sound to send to the radio.? Personally, I would go to the Windows level setting mentioned above, and see if you can get the radio to come to life by slowly adjust the slider from nil upward.? There's no harm in leaving the radio in transmit if it's not putting anything out.

Computer audio systems were (in my humble opinion) easier to deal with on Windows XP or even Windows 3.11.? Since Windows 7, things have become much more obscure.? Not that other OS settings make it easy either.

Well Charles, I thought I wrote a reply, but I can't find it. I did follow your instructions and found I can adjust the output audio. What I find, though, is I can adjust it to get a full bar graph, but then it dros to about 50% over a few seconds. What might that mean?
