I suspect the nub of Andy's problem was the list of potential buyers that was run for many months before you understandably decided it was too much effort for too little gain to chase up the people on the list once you had stock available and opened purchase to all comers. I think quite a few on the list thought the list was still active and that you would get to them in time, so didn't respond to your "all comers" invitation, hence didn't actually lodge orders with you. I know I nearly fell into that category.

Re: Sbitx and ad831 mixer
Tx works!!!!
Did a little board to swap the clocks and another board to switch rx/transmit audio and tx/receive audio. Very low power but enough to listen on a handheld radio!!!

Re: Renewed attempt to hack together a workable PA
As often happens on the group, we seem to have several threads running simultaneously. I believe Bill was responding to my post about the prospective board and semi-kit buyer list that was in operation in 2023 and earlier this year. I agree with you fully Bill, no more lists.

Too bad. It would be an instant success.
I can only think HF Signals cannot afford the little investment required (which is not so comforting...)

I soldered in a 20 amp diode(20A10) as a reverse shunt; it's what I had laying around.? Note that the markings on the sBitx circuit board where the power comes in are reversed.? That plus sign on the board should be a negative.? I know the solder job looks bad but I did put a lot of heat to it.? I just couldn't get it shiny.?

Good job! I noticed the mismarked board when I had to change out the board under warranty. I am glad you mentioned it for those unaware.?

N1EDC,
notice that there is the 32-bit original sBitx application, which you received with the device, and there is the 64-bit application, which is installed on a newer OS, Debian 12, if you flash the image to the uSD card. A team is working on its 64-bit development, so more changes are expected in the near future. Part of this is that you can find AM mode on 64-bit, on version 3.027 since mid-July.

Re: Upgrade to "sBitx 64 bit v3.1 - BTS"
Shawn,
?
Here are a few more reasons, in addition to what Gyula mentioned:
- I quickly grew tired of constantly providing scripts to fix issues in the 32-bit build.
- I did this early on with the 64-bit builds, but with mass kernel upgrades, new software installations, and system feature changes, things inevitably break. I’m no longer interested in fixing these issues, as people often end up either troubleshooting them on their own or asking me for help.
- I'm the one responsible for supporting these problems when they arise. Right now, the image process is what works best for me.
- I’m not endorsed or compensated by HF Signals. I do this in my spare time, balancing it with a full-time job and raising kids. I’m too young for retirement :)
?
Once someone installs the 64-bit image, whether it's an older version or the latest, the repository is there to pull in new features for the sbitx app. So, they just need to install the image once if they want to maintain it themselves and update the sbitx app with the ./update script.
?
I’m always open to help in improving this process. If you or anyone else is interested in contributing, feel free to contact me directly or through Discord.

I would favour keeping (and providing as images on cards) a freezed stable 32bit version, and move on with the 64bit one.
(the former installed by default on the pi zero powered units, the latter on the pi 4 ones)

Re: Upgrade to "sBitx 64 bit v3.1 - BTS"
The original sbitx is 32-bit, while this fork prefers 64-bit, for several reasons. If you have a 64-bit operating system, you can update the previous one with ./update without any further ado. Development is currently underway on several threads. I'm just writing this for your information if you don't know the history of this thread.
The installed applications are the available versions, which were included in the image file because most of the users are radio users rather than people who know Debian well, all of this can be read from the questions asked.
