Re: VARA.exe in Linux on a Chromebook (4GB RAM, 16GB eMMC)
Hi, Bob,
I missed your answer and found it only now. What you propose is an interesting idea. So far I had the impression that wine32 requires wine (64-bit base) to be installed. I will ask someone at winehq or in a related forum. OTOH wine32?+ win32 architecture install libraries 64-bit version of which seem to be present anyway in the system (current Debian is 64-bit only IIRC). I think I need to be looking for 32-bit (i386) Linux, but I am afraid that has been long unavailable.

Hi Jindra
Not an expert on this so mainly thinking out loud.?
I assume you space issue on the 16GB came from installing wine32
and the i386 linux architecture on top of the 64bit? (ie sudo dpkg
--add-architecture i386) There doesn't seem to be a wine64
dependency on the wine32 installation (in Debian) so maybe see if
wine32 ONLY can be installed? (assuming you don't want to run any
64bit Windows programs). WineHQ however has lots of useful info.
Maybe think about doing a manual strip of unused
applications/libraries first?

Hello,

recently
I purchased and reflashed Lenovo N23, 4GB RAM, 16 GB flash.
Running JS8Call to my complete satisfaction, using QDX and/or
QMX transceiver (both have built-in USB CDC's for serial and
sound interface). The chromebook runs from full charge at least
9 hours, maybe more. With QMX, QDX except battery there are no
extra boxes or parts to take in my backpack, such as digirig
etc.

I
tried to install VARA (because it's a standard in one of emcomm
groups I participate in) but no success, the reason being that
VARA is available as Win32 app only and the necessary libraries
don't fit into the 16 GB disk. Were it 32 GB or were VARA also a
x64 app everything would be fine. I tried to convince the
author, EA5HVK, to make a 64 bit build alongside the 32 bit
version but he seems to be reluctant to accept any proposals. I
wonder what will he do after 32-bit layer disappears from
Windows (after 2025).

I
just received a used Dell Chromebook 11 3180 with 32 GB flash,
reflashed it after some struggle and so far everything seems to
work. I have not yet started installing the VARA stuff.

Would
you know of another solution as alternative to hunting 32 gig

headache" variant has already been taken by Jose (EA5HVK) but he
doesn't know that due to Windows quirks our radio club 24/7 JS8

Re: Where to send user modified/tested/debugged sources?
Maybe using git would make this much easier? SourceForge is not a kind of source code repository made for collaboration, it is rather an advertising display.
73 Jindra ok4rm
You are probably aware of the preferred?C++ coding style, but to refresh you memory read here:?
1.? The easiest way is to submit a compressed source file containing all new or modified source files.
2.? Next would be to create a diff file for the entire application source.? You would need to build the diff based on the original uncompressed tar.gz source image and the modified image.
3.? Finally you can become a git developer with your own private upload directory at Source Forge.? After getting over the learning curve bulge this is the simplest method.
Send the files generated (1) or (2) to me at w1hk25@...

Re: Linux Mint works on one user account but crashes on another on Linux Mint 22.1
Hi John
Just some thinking out loud. I can't speak for wfview.
My first thought was that if the .fldigi profile/directory was
simply copied, then there are some hard references in the config
files that will point to the other user's structure. eg
fldigi.prefs has a reference to the macro file and fldigi_def.xml
has various file locations that may need editing. If copied as
root the r/w permissions also may need to be updated.
You did however say "created the profile twice", (which profile?)
so are there any group memberships setup for the first account
that are not in the 2nd? The one that comes to mind is the dialout
group, but depending on your environment may also include "audio".
I am assuming that you are not running the user programs
concurrently, nor have any user specific program or library
installs.

Re: Linux Mint works on one user account but crashes on another on Linux Mint 22.1
One suggestion to troubleshoot this crash would be to use the 'strace' command on fldigi. This will help pinpoint where the failure is occurring.
If you're launching fldigi from the terminal, you could use a command like this:
``` strace -ff -tt -o strace fldigi 1>stdout 2>stderr ```
It's best to run this in a fresh directory, as it will create a 'strace.<pid>' file for each process forked by fldigi. It will also collect the stdout and stderr output from fldigi.
If you could share the generated strace files, they might provide clues about the cause of the issue.

Re: Running Linux on a Chromebook
Hi, Roberto,
software packages from repositories are usually quite out of date. If you need to support CAT of newer or less popular model of trx, often it helps to build the software from source.

Any other ideas before I ship the radio to Yaesu? It suggests that maybe an audio switch or amplitude setting for the Tx/Data modulation is somehow turned off or to zero. Could also be the old left/right channel swap problem. I'm not sure about the detail of the FT-991A modulation source configuration. I suppose I could download the manual and have a look, but lack of familiarity means that you might spot something more easily than I will. -- Brian G8SEZ

Re: No RF output on digital suddenly
Chances are, you are sending audio to the wrong USB speaker port.? This is digital and we are sending SSB.? If the radio isn't getting audio input, then you get zero power out - that is the nature of SSB.? You did some switching around with speakers, your driver?names may have changed.??

I have an sBitx v3 that has essentially not modified, other that a dist-upgrade (It runs some Raspberry pi version of Debian). The full power is 25 W, and when I set the PA drive to 63%, I get 10 W out on CW, as expected. However, when I run either fldigi or wsjtx with the drive set the same, I get 1.3 W. On both, the power sliders are set all the way up to max (0 db). Both are using hamlib. The only thing I could think of checking is the ALSA mixer, but no numbers are small enough to account for a loss of a factor of 8 in power. Any ideas on what else I could check?

Re: FLDIGI 4.2.06 / RumLogNG v 5.19.1/OSX / MacOS 15.3
Tim, maybe I am not understanding the issue here. The very first thing you need to do is to find an RTTY signal and make it visible in your fldigi waterfall / passband. And you should be hearing it through your speaker as well.
?
If you cannot see the RTTY signal on the fldigi waterfall, then you will not decode anything.
?
I'll refer you again to the two screen shots from a couple days ago, where I posted one in "DATA" mode and one in "FSK" mode. The other guy's signal is visible with two yellow stripes with a blue background.
?
I am also a little confused about what fldigi is showing for your system, being in LSB mode and a 50 Hz bandwidth setting. My biggest convern here is that if the radio is actually receiving LSB mode then it might be necessary to "invert" fldigi decoding.... but you said that you are decoding fine in the DATA mode, so as I said, it is confusing.

Re: FLDIGI 4.2.06 / RumLogNG v 5.19.1/OSX / MacOS 15.3
Hi Dave,
?
I am sorry I captured the wrong picture on the FSK one I kept adjusting the S/N number from dark red to light yellow and could only decode noise. ?I did widened the filter and that did not change much. ?The immediate ?time I moved to Data it decoded the RTTY. ?Now in FSK my radio could decoded the RTTY but FlDigi could not. ?
?
What else can I test to get this worked out. ?

Re: FLDIGI 4.2.06 / RumLogNG v 5.19.1/OSX / MacOS 15.3
Hi Tim,
In your second screen shot I do not see any signal in the passband, but instead, I see a LOT of noise. Earlier you said
?
> ?I opened the filter on the FSK to get more of the siglanl into FLDigi
?
I am not sure how you did this, but from this shot, there is no signal there - only noise. With no signal to decode, that is, the pair of tracks like we see in your first shot, those centered at 700 Hz, 1500 Hz, and 2500 Hz (approx) there is nothing for FLDigi to do.
?
Take another look at my earlier post with the two screenshots of the waterfall. You can see that there are signals in both pictures, with the biggest difference being the width of the passband, and because of that, more signals to decode in that first one.
?
I think this is what you will need to do, and with your radio (not fldigi) so that there is a signal to decode. Once you have a RTTY signal transmitting so that he is in your receive passband, and it shows up in the fldigi waterfall, then fldigi will be able to lock onto it and decode it.
?
Thanks for the full screen shots - it is very helpful to try to figure things out and to understand what is going on there. "More information is better"
?
