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.

Hi All,
The first time I used Build-a-Pi (V2) I found that a complex Home wifi password can cause the Build-a-Pi script to fail an only complete a partial install.? I believe this was because the complex password acted like an injection attack by including characters that couldn't be handled by the code.

Basically entering the home password in the hotspot step caused the code to fail a few hours into the install process, post the FLdigi build. Attempting repairs via fix missing or re-running the script didn't easily work as there were many packages with issues.? I expect this may still be the case in V3 but when I last installed a new image using V3 I used the following workaround so haven't test it.?

If you have a complex password the simple solution is to write a new image the SD card, set the SSID but leave Home wifi password field blank when running Build-a-Pi.? The password can then be added post install.? When this is done everything works as advertised.

Brilliant job Jason,

Build-a-Pi made everything fairly painless even with the re-imaging the process the first time around

Thanks?Neil

2.2.2 has issues with fast decode in addition to other problems on windows, had to roll back to previous version. Suggested fix in windows was to not use fast and disable AP.

It was time to make a fresh build so I set up 3.02 from scratch. Build ran OK overnight. Only thing I noticed Conky not starting automatically, needs to be run from command line.

I guess this is more of a hardware question so I hope it's OK here. ?I bought the power board that Jason recommended in one of his videos. Doesn't fit with my Cana kit case. Is there a better option or is it time to break out the Dremel?

Thanks for any suggestions.?

That document is a bit dated now. As soon as I can find time, I will update. The day job has me super busy for the next couple of weeks. Have you taken a look at Build-a-Pi?


It does the heavy lifting for you and only leaves you some basic configuration to do after the build.

I was able to use the Mobilinkd config app on an android tablet to change the tx delay setting. I think that worked.?

One connection with a 1200 baud node completed, but that was the only one. I think there may be an incorrect setting, its suspicious that the connections all failed. I'll take a look at pat config settings.

Doing a manual build.
Using the commands you have in your build notes

Should be line 69 in the direwolf.conf file.

Ryan,

Have you checked the mobilinkd settings to see if a delay can be set? You might want to ask Rob (Mobilinkd developer) if it's possible. /g/mobilinkd/topics

Are you doing a manual build or using build a pi?
