Have to run "sudo chmod a+rw /dev/tty..." every time?

 

I figured this might be a good place to ask this.

On my Linux Mint laptop, every time I want to enable CAT control for JS8, WSJT, FLDIGI, etc, I have to open terminal and enter " sudo chmod a+rw /dev/tty..." replacing the "..." with whatever serial device ID like USB0 or ACM0. I can't remember how I learned this trick, and honestly don't have a clue what it means. Is there some way to make this permanent?
I hope my question makes sense.

I don't know if this helps but VARA works well on my 64bit windows system working with winlink.

Re: vara install

 

you would need to have a functioning 32bit wine box combo ¡°wow¡± to emulate 32bit x86 code in wine on arm/pi yes?

the quickest way for ¡°ham radio apps¡± is to stay in 32bit OS, as it¡¯s less configuration needs?

its all under a lot of active development, as for the error on wine and all, you can suppress them but there could be a lot. stuff changes weekly almost so unless your on-top of things, I saw a box update rolled out this week.?

Two months back the pi-apps project kept 32 and 64 bit wine box combo on the pi5 but instability abounds for everyone.?

The wheezy project and its latest forks keep a list of some updated packages.?

Re: GPS Update Tool - I want to set time based on its data from my iPhone - possible?

 

I use a number of BU-353 GPS puck receivers with RPis with almost zero
problems. There are a whole bunch of various GPS puck receivers out
there from $20-50. You don't want a dongle, you want a puck on the end
of a wire.

everything configured - and had location being delivered to the RPi from
my iPhone. But - the time was off by about 45 minutes (probably when I
shut down the RPi before heading to the park).

Is there a way to have the RPi sync time with the incredibly accurate
time from the iPhone delivered in the GPS data?

Ultimately I used "sudo date -s "date/time string" --utc

Re: GPS Update Tool - I want to set time based on its data from my iPhone - possible?

 

You could do a few things, but to?set gpsd to listen for a push from the app (example config of port 9999) is one, this way most Linux can talk gpsd. Link your phone to device via WiFi hotspot. Use the device IP addresses. Push from phone to device IP:9999?


Edit the /etc/sysconfig/gpsd or could be /etc/default/gpsd config file and make sure that the OPTIONS parameter has a UDP source that accepts packets on port 9999 (for example)?

# Options for gpsd, including serial devices

OPTIONS="udp://*:9999"

# Set to 'true' to add USB devices automatically via udev

USBAUTO="false"

Re: vara install

 

You need to invoke wine to run the installer for vara, so by changing to the directory of your downloads.. cd Downloads?

you can find the .exe setup file for VARA and from command line ¡°wine ¡­¡± you can press TAB to help suggest completion?

copying the OCX failed because it sounds like you didn¡¯t install Vara yet

The tips I gave are not exact but suggesting the direction to fix issues, if that helped I hope.?

vara install

 

On install vara failed
Did this:
Load up Pi-Apps via http://pi-apps.io
?wget -qO- https://raw.githubusercontent.com/Botspot/pi-apps/master/install | bash
?
Use the Pi-Apps GUI navigate to Tools->Emulation
?install Box86 and wine
ok
then did this:
wget -r -A "*.zip" 'https://downloads.winlink.org/'
ok
unzipped files "here"

then tried this:
?
I copy all the OCX files in VARA rather then set paths or register
?cp ~/.wine/drive_c/VARA/OCX/* ~/.wine/drive_c/VARA/

failed

then
tried this:
"wine VARA setup.exe"

failed some errors


What am i doing wrong?

Re: VARA in Dec2023 on a Pi

 

Yes image a 32 bit OS?

unless you already got it all working on 64bit hihi?
64 has some performance gains for sure but the trade off is more hiccups currently?

Hi Kelly,

Can I ¡°flip to 32bit OS¡± on my current pi 5 install, or do I have to reinstall the OS from scratch fresh as 32 bit and start all over again ?

Thanks,

During install vara install failed , its in menu but does not work, conky tab on desk top but just a blank black space displays.

Did I install the right version ? where do I get and updated version.? tried to reinstall conky ended up with same results.
A great project just a bit overwhelming trying to get up to speed.
Any tips help is appreciated.

Re: ARDOP GUI

 

There are some differences with what's installed on the Pi with 73Linux and an x86 machine. The ARDOP GUI being one of them. The GUI isn't an option to install on x86 machines with 73Linux. You will need to install it manually.

Re: RPi5-NVMe

 

VNC Fixed. Port Conflict
I had to shutdown the service.
GoTo Pref/RPi Config (pull down menu) + turn on VNC (again)
Reboot (??) not sure...
Now, the task bar (moved to the bottom) icons are now in the middle, not left (as set ??)
I also added "TEMP" to the right info with the time...? Yes, Conky has the same info...

73, steve WB3LGC

I should be ready to take the RPi5 camping this weekend (I will take the RPi4, too.)
I hope to be on FT8 from Dover, DE (Akridge Scout Reservation) as a Campmaster.
The RAIN forecast may limit my antenna to a mag loop.? KX3 with 12 Watts.? Maybe a longwire??

Re: RPi5-NVMe

 

OK, I made the change to X11...? Now VNC connects to the RPi5, but Wayland (??) RPi5 (WayVNC)? ??? blank screen with a cursor...
73, steve WB3LGC

BUT, yes - wxjt-x and conky are acting better (monitor).
I think in the past, I changed to X11 before using VNC ???
I "was" calling X11 --> W11, I am having issues with Windows 11 too, and I shorten to W11.
I am not that far along that I can't re-build from scratch...

[Edited Message Follows]

hello,
as mentioned in my messages a few days ago (message/12674 'Linux73
install failed') I had issues to start ARDOP. I tried Dominic's
proposal but it doesn't help.
I did some additional checks and did find that in BaP install there are
2 apps to choose: 'ARDOP' and 'ARDOPGUI' -in 73 Linux install there is
just one: 'ARDOP' -see screenshots. Is that the reason why I can't get
ARDOP running? 73 de Tom, DG6TOM,
KC6TOM

BaP is installed on a Pi3, 73 Linux is installed on a ThinkCentre small
desktop
Assuming that this ThinkCentre deskop is a full pc, you have a x86, more
a x86_64 CPU inside.

Having a Raspberry Pi 3 you are limited to a ARM CPU, that does not have
a full x86 instruction set to work with.

Those two differ and so differ the applications that can run on those
processors finally.

That is also the reason the Raspberry Pi version of ARDOP is called
piardopc while the x86 version is only called ardopc (and the x86_64
version is even called ardopc64 (or piardopc64 on the Raspi)).

We do have 4 different versions of apps:

- raspberry pi processor (ARM)
- 32 bit piardopc
- 64 bit piardopc64

- normal PC
- 32 bit ardopc
- 64 bit ardopc64

And those are still not the same as the ARDOP_GUI tool, as the GUI tool
is just a wrapper for the actual program. The GUI makes it comfortable
to work with, but you still need the low-level application on your
system.

If you run `uname -a` you will get almost all information about your
used CPU that will help you to identify the correct version for your
system.

Now it depends what operating system is running on your Thinkcentre, as
that will finally limit what version of ardop you need to download.

So please run `uname -a` and decide which version you need to download
or let us at least know what the command tells you so we can give proper
hints to a possible solution (or non-solution HIHI)

I hope that makes some sense.

Re: RPi5-NVMe

 

Yes, thanks for the reminder.? My RPi4 is set for X11.
My main reason for my email was to show/say that WE can get V5 and it DOES work with NVMe...

I very much like the POWER button, too.
73, steve WB3LGC
Re: RPi5-NVMe

 

Switch to x11 vs Wayland in raspi-config tool for more compatibility, xastir and grid tracker are a few others which will behave oddly at the moment
