Many have requested an sd card image as an alternative to upgrading the sbitx software.
Upgrading the software is the recommended way to go as it preserves the personal settings, logbook etc. Using a new image on the sd card is the equivalent of reformatting your hard drive. This? option is only for those who want to reset everything and start all over again.
Here goes:
The sbitx sd card image is available to download from:
1. Download by clicking it on the above link. 2. The image is zipped up to save download time, unzip it with your compression utility (on most operating systems, just trying to open it will automatically offer to unzip the file). 3. Follow the instructions to burn it to your sd card from:
4. You will need to calibrate the tx power again. Follow the instructions? on :

Hi Farhan -
There may be something wrong with the image file.? ?I extracted the image file from the rar file and tried to use the Raspberry Pi imager "use custom" option to install it on a 32G card.? ?I got a message "Storage capacity is not large enough.? Needs to be at least 31.9 GB"

You need a 32 gb card. I guess you are using a smaller size sd card.

Hi Farhan,
It is a brand new 32G card.

Yes, the Raspberry Pi immature version 1.7.4. And I just successfully installed the default pi image with no problem.? ?For your image, I used the "other" image menu and selected the file that was extracted from thr RAR file that you posted.? Your file had no extension so I added a . IMG extension to the end so it would find it.

Hi Dean,
When burning the image to a Micro Center 32GB card, I encountered the same issue.? Those cards do not have 31.9GB free.? To not waste more money on another card that is not larger than 31.9 GB, I bought a 64gb card and used it.? 64GB will work, as will any card larger than 32 GB.
It would have been nice if Ashhar Farhan had made the image smaller than 30GB so it could be burned to any 32GB card.? The space used on the card is much less than 30GB.

Hi Evan,
I'm using a SanDisk Extreme Plus.? A little bit of web searching shows that essentially all "32G" report 29.8.
I can get a 64 tomorrow and try again.

MicroSD card manufacturers exclude defective cells from use during production.
For this reason, a card called 32GB may not be usable, because, for example, Farhan wrote the image on a high-quality one, and whoever copies it has a card that is a few bits smaller. That's why you can't write on it, even though it's called 32GB.
At the end of formatting, you will get an information window.
There you can see how big the card is and compare it with the size of the image.
At that point, it is already clear whether it will be writable.
Those who use Linux have the option to modify this under Linux and make it a little smaller, which can already be written.

Farhan,
So what is the power calibration procedure on a DE sBitx using this image file? There is no SWR bridge in mine or internal power meter, so whats the best way to calibrate.

Success with a 64GB card. I can assert that the software definitely loads on a Pi 3B+.?? At the moment I only have the Pi and display and no other hardware. The radio interface doesn't come up, but I didn't actually expect it to.? I'm going to investigate modding my uBitx.? Ore may break down and buy the board only. 73, Dean KK4DAS

Hi Farhan, You may wish to consider using the 'Raspberry Pi ' SD card copier' next time to duplicate the image to a smaller SD Card see: . The SBITX card image can then written to any size SD Card - provided the contents fit. When reinserted into the Pi in the SBITX, the partitions can then be resized to the full size of the card easily using the 'raspi-config' program
- sudo raspi-config from a terminal
- Choose Advanced Options (option 6)
- Expand File System (option A1).
Paul.

Joel,
I believe that you’re supposed to use an external SWR meter. Here is YouTube video that Ashhar made.?
The software versions are the same, so I’m pretty sure that they use the same calibration, someone correct me if I’m wrong.

Has anybody out there managed to successfully burn this to an SD card? Most of mine complain that they don't have enough capacity; the one that doesn't gets an I/O error near the end. Maybe the original card would work but I don't want to burn the image to that one; I'd rather have the original available there as a backup.

Shirley,
Try burning to a 64 GB or larger card.? Most 32GB cards are just a little shy of the image size.? There are ways to make the standard image smaller; it has not been done to date.

Could do that, but I'm reluctant to because I only have a couple of 64 GB cards and LOTS of 32 GB. The images really should be prepared the same way the official Raspberry Pi OS ones are; they're small to begin with (I think they'll still burn to an 8 GB card), then expand the file system to fill the card the first time you boot the system. At the very least we could get Ashhar to use a 32 GB card that is at the low end of the size range, rather than one that is at the very top...

If
someone is having trouble because they cannot copy the image to a 32GB
SD card, because there is a few bits less space on the card. I recommend the following:
?
The solution may be to first copy the image to a larger, for example 64GB uSD card (use balenaEtcher prg).
You start the RPi with the 64 GB card, then copy it back to the 32 GB card with the SD Card Copier program.
To the card you couldn't copy to because there wasn't enough space. This is the simplest solution.
You don't need shrink, you don't need linux os. By the way, the sbitx_v2 image takes up about 9 GB of space.
?
Yes, I tried it and it works.

Shirley,
I have read that there are ways to take an existing image and shrink it after it has been created.? That is done on a Linux OS, not a Windows.? I have not tried it.
I agree that it would be nice if Ashhar Farhan would save the image in a smaller size and store it as the "Official" image.
