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.

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.

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.

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
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.

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.

I have seen that and it appears the variable rate tuning software is twitchy.
If I tune up it behaves.? If I reverse suddenly it jumps.? If I pause then reverse it behaves.
Its a bug.

I have to share this, and it may already be common knowledge in the group. Maybe it's even in the sBitx manual that I did not read yet.
Spent a lot of time attempting to make a backup of my original SD card supplied with the sBitx kit.
Used Belina Etcher, Raspberry Pi imager and Win32Diskimager and was not able to make a copy.
All three of these apps reported that my new SD card was "too small" for the sBitx image.
Finally got it to work with the SD Card Copier that is on the sBitx and maybe all Raspberry Pi's running Raspberry Pi OS.
Just look in Accessories and run SD Card Copier.?
Pick the internal SD card as the source (the name will be something like: SE32G (/dev/mmcblk0)) and the Copy to Device as the SD card you want to copy to.
You may have to put the new SD card in an adapter and put it in the USB slot before bootup for the system to see it.
So best make a backup before mucking around with the system.

Found the fix for my error in attempting to configure the Fldigi and Flrig apps was to:
First download the sBitx? "can't wait" image and locate the fldigi_def.xml.
The file was located in a hidden directory? ?.fldigi? ? full path /home/pi/.fldigi
Then replace it on the system that was presenting the error.
The correct settings may have been in the fldigi_def.xml-old file, but I did not think to check it in my sleep deprived stupor.

CW decoding worked for me but strange enough when a stronger signal just outside the passband was present. When the spectrum was clean and only the CW signal could be seen on the spectrum I couldn¡¯t get the decoder working. Guess that it was just a coincidence and decoding with fldigi is a lot more critical than with the decoder between the ears.? Vy73 de

?Further testing of this early this morning.. I noticed that the "window" for? receiving a signal was centered n the screen, and thus a signal with your new code was about 1kHz higher than with the original code. Also decoding of cw seemed to stop.. I'm not familiar with the fldigi for cw, butt hat's what seemed to happen.. This is probably really old news now.. but FYI Brad

Would it be possible to create IQ from the mono baseband? Like this does in fig. 2 from RF.
