Thanks, Neil!

That did the trick.

FYI,

CHIRP shows need for update, but nothing changes after running BAP 3.0.2 three times.

Just something to throw into the 3.0.3 "job jar". :)

Looking forward to 3.0.3 and ability to use the new GPS that you have now changed over to.

Hi Jeremy,

I haven't tried to do that yet.? I'm brand new to RPi and WSJT-X.? My guess is that it is probably possible and might involve issuing a command via terminal that pipes the sound from the default soundcard (Sabrent) to the RPi analog device.? There may be an alternative way to do this if you have pulseaudio installed but I'm not sure.? Good luck!

Hi Jason,

I noticed in your video (at around 10:00) that when you were adjusting the volume setting sliders, you had the mic enable box unchecked.? Was that intentional and if so for what reason?

In your audio settings for JS8call and WSJT-X, your soundcard shows up as alssa_input.usb-C-Media-...? ? ?My C-Media soundcard doesn't show up in the pull down menu but as I mentioned I just selected "default" and that seems to work fine.? Any idea why we have this difference in out setups?? The only reason I can come up with is that you were using an earlier version of Buster than I am and perhaps something has changed.??

Let me know if you have any other thoughts on my original questions.? Thanks much for your help!

73,

Ron

Does this case also allow an RTC to be mounted on top of the power board?

I cover the way I set my audio in this video ? The sound settings start at the 9:05 mark.

With the pi 3 and pi 4, none of the background processes should interfere with decodes. To see what's running, use the top command in a terminal window.

Easy to fix, just right click on the taskbar at the top of the screen and then select the 'Add/ Remove panel items' option
from here you should be able to select the 'panel applets tab'.
The Launchers or shortcuts reside in the 'Application Launch Bar'? I'm expecting it will still be there although you may need to scroll down to find it, if not you'll need to use the [Add] button to add it back.? ?

To re-add terminal and other launchers select [Preferences] button and navigate around the installed applications in the right hand pane to find whatever applications you want to add. Use the Add, Remove, up and Down buttons to modify the Launchers shown on the left.

This is also a good time to add other items like FLrig that you may use often.

Another tip that may also save you a bit of time if your are in front of a keyboard is Ctrl+Alt+T to open a terminal window.

I finally found a few extra hours to build and test this little circuit and it works great for talking to my icom-746. Now I just need to rebuild it on a protohat with a connector for a GPS and RTC.

I am embarrassed to say that in playing around with the bar at the top of the screen, I managed to delete the icon for the terminal and the main menu.? If I had either, I could get the missing one.? But now I'm stymied.? ?Suggestions?

Thanks and 73

Last minor edit for today:
After installing ie6 (or probably also ie8, though I haven't tested it), and putting the Microsoft pdh.dll into ~/.wine/drive_c/winedows/system32, DLL overrides are no longer needed at all.? Don't worry about editing user.reg or about adding a pdh override.

Minor edits: [TL/DR, make sure you also install internet explorer in your wineprefix: ie8 can only be installed on the x86 linux laptop, but ie6 will install in Pi/ExaGear]

1. I've been trying different combinations of components in different wineprefixes and internet connectivity seems to not work or partially work in some of my wineprefixes. By 'partially working' I mean that HF Channel Selector gets stuck "Downloading channel records from the Winlink databse..."? I recommend installing gecko+mono+dotnet35sp1+ie8 on the x86 laptop's wineprefix?(with "winetricks?dotnet35sp1 ie8", then click yes to mono and yes to gecko) before tarring and transferring the tarred wineprefix to the Pi.? If your wineprefix is already on your Pi/ExaGear and doesn't have ie8, you can run "winetricks ie6" to fix the HF Channel Selector stall too.
(Notes: Wine will check ~/.cache/wine for Mono and Gecko install files. If it finds those install files, Wine will automatically them into a new wineprefix. If it doesn't find them, Wine will ask you if you want to install Mono and Gecko - click yes to both).? IE8 won't install in ExaGear.

2. Even if we fix the stalling problem, the RMS Express?HF Channel Selector doesn't seem to work quite right in CrossOver or in any wineprefix I can conjure up.? The Channel Selector is functional, it just takes about 5 minutes to update its propagation indices and sometimes crashes the first time it's loaded.? Just restart it if it crashes.? If you let it run for 5 minutes, then you shouldn't have to do that again - just don't hit the Update Table Via Internet button.? If anybody figures out a fix for this, let me know.? I'm currently experimenting with ITS HF:?

3. An old, working, pdh.dll is actually available for download direct from Microsoft (??), which includes a note that the file is distributable for Win NT.? This exe is actually just a zip file, which can be unzipped with the "unzip" command in the linux terminal (if unzip is installed).? Thus, we are no longer reliant on the zip file on K6ETA's blog or sketchy DLL files.

4. I've made some commands to automate the downloading of components we need:
Winlink Express (formerly RMS Express): https://downloads.winlink.org/User%20Programs/

cd ~/Downloads && wget -r -l1 -np -nd -A "Winlink_Express_install_*.zip" https://downloads.winlink.org/User%20Programs

sudo apt-get install megatools -y && cd ~/Downloads && megadl 'https://mega.nz/file/HHAEmQAK#-u8Nje0GcMfcsCdsCHJqHvDcDrIyEn7LKjd9vMwSsk4'

cd ~/Downloads && wget http://download.microsoft.com/download/winntsrv40/update/5.0.2195.2668/nt4/en-us/nt4pdhdll.exe && sudo apt install unzip -y && unzip nt4pdhdll.exe && cp pdh.dll ~/.wine/drive_c/windows/system32
# don't forget to add pdh to winecfg's DLL overrides: Use (native, builtin)

I set my Sabrent USB audio device as the "default" by right clicking on the speaker icon in the Buster GUI and then selected it for output and input.? I then adjusted the levels/sliders for? speaker, mic and capture.? I checked and these settings are also shown in alsamixer.? I also check the .asoundrc file and it shows the card 2 (USB device) being selected. Then I selected "default" for input and output under the audio tab in WSJTX and everything seems to work. I'm not running any other applications at this time. I have just a couple of questions.

Was the above approach the best way to set up audio?
Is there another approach that might provide better performance and reduce any potential latency?
Why are there settings for both Mic and Capture?? How do these relate to each other?
Is there any risk of the RPi generating some beeps or other audio that may end up getting transmitted?? If so, how can these be silenced?
Unrelated to audio - are there any background processes running on the RPi that can potentially disrupt decoding at times?? If so, can these be reduced in priority or suspended?

Thanks for your help!

Nigel,

Is your user still pi? Are you auto logging in on boot?

Current version 3.0.2 won't start Conky if you don't auto log in. This will be fixed in 3.0.3.
