Re: zBITX CW Keyer
Ken, you may be right. I looked at some benchmarks and it looks like the pinfour can be four times or more faster than the 3B plus.?
if that turns out to be the limitation then experienced CW operators might just have to wait for a faster processor or more RAM or something
It’s just surprising because a small change in the software of the SBitx, even tripling. sampling rate would likely work just fine. Johnshoy’s fix multiplied sampling by 20 times!! ? That was probably overkill, but it works great. You would think a similar solution on the slower processor could be arranged to give similar outcomes.
however, perhaps not!
?
A new processor comes out every so often so eventually, this will get fixed!!

Re: Does sequence of updates matter?
I have connected to a monitor and started the zBitx. Evidently, zBitx got deleted as part of the fw update - it no longer opens when connected to monitor. The only window now open (on monitor) is the pi@sbitx: `/sbitx window. From where can I download and reinstall the zBitx program?

Why only 18? sBitx has an RPi 4, the zBitx has an RPi Zero 2 W, effectively a low-memory RPi 3B+ (the CPU on the Zero 2 is the same as the CPU on the RPi 3B+).
?
The processing of the RPi 4 is significantly greater than the RPi Zero 2.

Just for giggles I did try the ./update thingy. Here is the output. Might ring a bell for you that understand far more then myself:

We had to bump up the price to be able to buy key components faster (ex-stock). We have also been hit by some strange duty getting the PCBs from China. We had to bump the price up by 20 dollars.?
Our vision was really to do a $100 dollar SDR, it just got escalated?to 169 USD

Re: zBITX CW Keyer
I cleared out /var/log and I updated the software this morning. The CW keying in Iambic B is still rough... at 22 WPM keying K gets me a Q maybe 20% of the time. I tested this with two paddles On Tue, Apr 1, 2025 at 11:44?AM John AE5X via <ae5x=[email protected]> wrote:

Thank you so very much for your attempts. I have tried it , but no luck :-(
Here the output: pi@sbitx:~ $ cd sbitx pi@sbitx:~/sbitx $ git checkout master error: pathspec 'master' did not match any file(s) known to git pi@sbitx:~/sbitx $ ls -l master* ls: cannot access 'master*': No such file or directory Bottom line is I guess that I still need to build a new SD-card with a fresh image. Thank you in advance.

Re: zBITX CW Keyer
Could this be as simple as debouncing the keying circuit? I have a 0.1 uf disc ceramic across the output of my J-36 paddles to prevent this. Lee KX4TT On Tuesday, April 1, 2025 at 11:00:00 AM EDT, Gerald via groups.io <hb9cey@...> wrote:
The new firmware v1.05 / v3.051 is slightly better than before, but since CW still doesn't work properly for me even with the new firmware, I compared it with the QCX-Mini. Both transceivers were keyed and monitored in parallel, at the same speed, using a paddle. I also tried unsuccessfully with another paddle. ? While the QCX-Mini didn't lose any characters, the zBITX repeatedly produced errors, dots and dashes were lost or appended. This happened at slow and also faster speeds. This reminds me of my simple diy touch paddle where I always had to wet my fingers otherwise exactly such errors occurred. ? It seems strange to me that everything works fine for other users. ? If I use a macro from the zBITX to transmit, the zBITX keys everything flawlessly up to 50 wpm. No lost dots or dashes. How can this be, and where is the difference between keying by macro and the paddle input? I'm neither an IT nor an electronics engineer, but I would first look for the problem with the key input. Perhaps someone can explain this to me. ? 73, Gerald |
