Why only 18? Current sbitx goes much faster! That seems like a serious limitation……

Good luck.

ps.: Sorry, but I remember useful information later. When you have successfully set up the Image, and you have completed your personal data and application settings, it is advisable to make a Backup (possibly more), because in case of any damage you can easily restore the system. You can do this operation from the currently running OS in the Menu with Accessories, then SD Card Copier.
Pay attention to which is the source and which is the target media. I copy to USB sticks purchased from different manufacturers, so I can easily identify them by name. The internal uSD is shown as mmc.
Always have a copy of the Image and you can copy (restore) the daily variables to a USB stick with the Toolbox / EZ Data application.

I got updated to 1.05 / 3.05.

Everything I have tested look s good!

WHAT A GREAT TRANSCEIVER!!!

Thanks.......

Dean,
since you are very new to the rig, it is worth doing it as you described. What Wojtek writes requires more knowledge about what and why you are doing.
But don't worry, because in a few days or weeks you will learn this knowledge from the wiki and the next step will be easy.
When you have unpacked the sb64p3.img.xz file, burn it to the new uSD card, according to the description.
After you have inserted the card containing the sb64p3 Image and started it, it is worth updating the sBITX-Toolbox (2.7 to 3.01)
The ELF image has a Hotfix, do this as well.
The sBITX-Toolbox is a package containing auxiliary applications that makes it easier to use sbitx. Open the Toolbox and start the update sBitx app in the Update Manager.
This will update the application from v4.2 to v4.4 and it is the latest. Use this later when an update is released. (Do not use System upgrade for now!)
I did not update with this because I often go ahead with testing and the last time I updated was by cloning.
If you've made it this far, all you have to do is familiarize yourself with Image's knowledge and the possibilities. So put it to use.

Ron it looks like ui_tick does not have the improvements that we have mostly added to everybody’s code to make CW work that were proposed by Johnshoy
?
?
if my understanding is correct, that oversight should be corrected.

You might want to look at the Winkeyer by Hamcrafters.? This can
take a string of characters from a host system, read them into an
internal buffer, and handle correct output timing.

Purchasing has been paused while they catch-up from the flood of orders they had in the initial release?
Hi friends,
?I’m new to these forums and I’m having problems navigating this app; I really don’t know where things are. Please, if anybody could point me in the right direction on how to purchase the Zbitx? A link would be helpful.?
thank you so much,

Hi Dean,
?
You may boot the rig from the USB pendrive if you change the boot order in your Pi.
?
In the terminal session, you may run "sudo raspi-config", and in the "advanced settings" you may change the boot order so that USB is tried before SD.
In my case, I had to update the rpi-eeprom package (otherwise the raspi-config complained: "no eeprom bin file found for version 2023-01-11").
?
In that way you may test if the new version solves your issues without disassembling the rig.
You may even replace the content of the SD card, when running from the pendrive.
?

Wojtek

PS I described that procedure in /g/BITX20/message/116658

Gyula,
?
Here is my plan. I am going to burn a new image on a new 32G card.
?
Open the sBitx and remove the card in the Pi
?
Replace the new card with sb64p3 into the Pi
?
Restart rig
?
How does that sound?
?

./update gives 3.021, not 3.05

I ran into this issue as well. See issue #2. I also am still having a difficulty getting FT8 to use the decode selected by clicking the encoder. Something?is definitely better because it is no longer locking the radio process on my zBitX when the encoder is used to select a decode, instead, it does absolutely nothing at all.
See new issue #1 on Github.
We're homing in on it, it's very close to working right! (At least on my radio. Of course, Finagle's First Law, "The perversity of the Universe tends to the maximum.", means that it's somehow possible for it to be working JUST FINE on someone else's radio, but MINE wants to be SPECIAL and isn't working.)

Using sBitx v3 with various firmwares without disassembling (also upgrading to 64 bit version)
I wanted to check the 64 bit version without disassembling my sBitx v3. It was possible via changing the boot order. The procedure is quite simple.
Just run "raspi-config" utility (in the terminal session and via "sudo"). Then in the advanced options you may set the boot order so that the USB disk is tried before the SD card.
With that I could boot my sBitx v3 from the 64-bit version installed (with dd) on the USB pendrive.
After successful testing, I could backup the original SD card. I have done it via dd, sending the output to the file on my server (mounted via sshfs).
I made a separate copy of the whole /home/pi/sbitx to recover the hardware calibration and my settings.
Finally I could install the 64 bit version with:
?
$ sudo bash
# wget -O - | dd of=/dev/mmcblk0 bs=4M status=progress
?
(172.19.1.1 is the IP of my server, where I have started an ad-hoc http server running "python3 -m http.server" in a directory where sb64p3.img was downloaded.)
After that I could mount the /dev/mmcblk0p2 partition and copy the saved configuration files.
The whole testing and installation was possible without disassembling the sBitx v3.

Re: ZBitx hangs on startup
Updated RPI and then was able to update zBitx SW.
All is well now.
Tnx,

Can you past the error or warning you got when you attempted to do the update ?

Re: sbitx v3 no output after upgrading to 64bit
Yes. I have backed up and restored from the 32 bit sd card. I just tried it again this morning with the same results.

Dean,
I'm just writing to encourage you that I've had the v2 hardware device since April 2023, which I started using since mid-November 2023 (with v3.0 alpha version). Currently, the 64-bit v4.4 firmware is the latest and I've made nearly 10 thousand QSOs in mostly digital modes with an antenna sized for 7 MHz and usable well on 7-14-21 MHz without an antenna tuner.
I'm writing all this because there is a possibility, if you're interested, don't give up and you'll learn a lot of new information.
