I only have one headset a Logitech USB H390.

Which audio device did you select? Did you try any other?

Any chance the humming is coming from a bad filter capacitor in a power supply? Jeff VE6DV

I loaded your program on a new RPi 4 - 4GB that is running the latest Raspbian OS.? Looks like everything is OK except for multiple reports of a humming sound on my signal.? I am using a Logitech

Thanks for the updates.? I re-installed your program and now it works well. N9KO Cal

First of all, let me start by saying: *Stream audio programming on Linux is challenging* *!* I am still learning a lot about ALSA and PulseAudio and how they interact. The good new is that... You now

John Hays posted an issue on the qdv github, listing several problem, the most serious was that audio wasn't working on Raspbian. After investigating, I found out that qdv not only depends on alsa

Sorry you're having so much trouble Cal. -- ___________________________ 73 n7tae (at) tearly (dot) net

qdv.cfg looks OK I ran the two diff commands and no errors were noted. Looks like this was not meant for me. Thanks for your time.I will monitor this IO group and try again as future version come

To completely uninstall, delete the build directory, ~/.config/qdv and the executable, ~/bin/qdv. If ~/bin is then empty, you can delete it. It's hard to understand why this would be necessary. That

Yes I turned it off and restarted it. When I start qdv again, I get the GUI interface. When I type REF030 C ( XRF757 A) in the "Linking" box, I get nothing in the large box at the top. I believe there

I don't have a clue about that one. AFAIK, qdv doesn't use hb-object-private.hh. In fact, the file doesn't exist on my test system. As near as I can tell, this is part of something called JetBrains

I re-installed per your Github instructions.? Had one QSO on? REF030 C.? Turned of the laptop and cannot have another QSO.? ? The line beginning qdv: ../..? appears after I click on the Quit

Sorry about that. Do a "git pull". I had some problems in the Makefile. BTW, I'm making some headway with DPlus linking, but there are still some problem... (sigh). --

I just did and it failed; calvin@calvin-Latitude-D830:~/DigitalVoice$ make make: 'qdv' is up to date. calvin@calvin-Latitude-D830:~/DigitalVoice$ make install mkdir -p /home/calvin/.config/qdv /bin/cp

Looks like you didn't do a "make hostfiles". -- ___________________________ 73 n7tae (at) tearly (dot) net

I could not copy the terminal output.? Please see the attached text file.

The following are the results when I run the make command for the attempted re-install on the first laptop and on a fresh install on a second laptop.? When I tried to uninstall I deleted the

I am unable to reproduce this. I can link to all of these reflectors. I'm not sure what you mean when you say "Everytime I get these errors". Every time you start qdv, or every time you try to link?

No thank you. If your device is showing up on /dev/ttyUSB0 but not being opened by qdv , then I think that means that it is not a fully compatible clone of an AMBE-3000 device. Without either a white
