Re: Gtk-WARNING: cannot open display (./sbitx)

 

Yes, I did another build. Same error.
as to the other question no, I am not trying VPN. I use the cmd line to show the error. Invoking sBitx by clicking on the GUI icon similarly starts the process but the hangs. See photos. The leftward green icon is used to start sBitx and the rightward free icon shows the process which no longer proceeds. And yes, invoking sbitx as ./sbitx from the sbitx folder through ssh has worked in the past¡­exactly as doing the same from a terminal on the sBitx screen. I use ssh because it¡¯s easier to read on my larger Windows screen.
Re: Gtk-WARNING: cannot open display (./sbitx)

 

Are you trying to run sBitx from another computer in a remoteterminal (like Putty)? Not possible.

You need a remote desktop or vnc or ...?

Did you do a ./build again after fixing permissions?

I see a problem. ?The directory and all the files in it are owned by root. ?You are user pi.

This should fix that:

cd ~?
chown pi:pi ./sbitx
cd ./sbitx
chown -R pi:pi ./*?

( I¡¯m always hesitant to do a recursive action like the one on that last line, but it should stay within the ~/sbitx directory and not hop out of there¡­. )

Could you post an ¡®ls -al¡¯ (no quotes) of your ~/sbitx directory?

Re: Sbitx #165 received today, thoughts.

 

One item noticed and causing concern is a very high current spike at startup.
How high?? Over 5A.? I noted this with mine as i added a fuse to protect it
and?on power up the 6A fuse blows, not a good thing.

I believe something is driving the power amp to full power momentarily and?
may have something to do with final getting blown up.? This is being
investigated and a solution should result.

While working with the radio use a current? regulated supply (set to 5-6A)
or fuse supply lead.? This may prevent disasters.

Re: sbitx in VSCode

 

You can if your doing cross platform compiles.? VSC is really a winders thing.

For Linux (intel/amd) and Rpi 3/4 (ARM)running Raspbian there are many
other choices for an IDE or environment.

Re: Corrupt rig XML defintion file #sBitx #sbitxedits #sbitx-k3ng

 

FYI for the non linux user (Rasbian is linux) p a file with .name
is generally not shown in a LS(DIR) or with the GUI file manager.
There is option LS-a to sho all (command line) or usually the file
manager has a setting that will show all.

If you have used linux this is nothing new but to winders users
it may be alien.

Re: N8ME_2_VU3GAO Firmware - Can it have same graphic style as the CEC firmware?

Great response. So I could go with Nextion / CEC on Ubitx V6? Scrolling posts couldn't get a super clear answer as to if it's supported.
Re: SD card backup #sBitx #sbitxedits

 

That is safe to do IF there are no other aps running.??

I found it easier to pull the SD and copy on my MINTbox
via a USB to uSD adaptor.??

I wonder if one could dd the SD card /dev/ and pipe it to netcat to another machine. ?I know it¡¯s a live file system, but presumably it would be in an OK state to burn on to a new SD card for a backup? ?Of course there¡¯s always good old tar...

Re: #sBitx Idea for sBitx surround sound cw #sBitx

 

I would think you can do whatever phase shifting or filtering you can program, but it would be outside the sBitx since there is only one channel for audio hooked up to the headphone from the codec.?
Re: sBitx - up/down tuning

Anthony Good

I believe the problem occurs without tuning acceleration activated, but let me know right away as I contributed the tuning acceleration code.

A few weeks ago I looked at the issue of the tuning seeming to jump when going down, and I couldn¡¯t see anything wrong in the code and strangely enough I couldn¡¯t programmatically confirm it was actually happening. ?But I felt like it was happening¡­. Hopefully that all makes sense.

Try disable tuning_acceleration.

Can be done from sbitx \cmd
at the sbitx-prompt write:

tuning_acceleration=OFF


another way is to edit /home/pi/sbitx/data/user_settings.ini
Restart of sBitx required.

Re: SD card backup #sBitx #sbitxedits

 

The base MPU module is Rpi running Raspbian linux.
I;ve used that for years as a HB laptop initially for fun
until I found it has enough power for serious work.

What that means is the computer in the box can with built in?
web browser (chromium) can easily surf the net (like HFsignals)
and even download files.? IT also has a software installer.

To use that plug in an eitherpipe or enable wifi and give it the
password for the wifi router.
