Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
Could any of these failures be caused by low current supplied to the RPi by the radio? I have noticed that it I try to connect an NvME SSD drive to the USB port, it¡¯s operation is erratic. I have no problems with the same drive connected to a RPi 400 powered by a 3.5A wall wart supply. I believe the sBitx only supplies 2A.
Also, the instructions in install.txt say to disable the low voltage warning, which does display if not disabled. Does disabling the warning also disable any low voltage protection?
Lastly, can I power the RPi by its USB C port while it is in the sBitx or do I need to do something to disable the power coming from the radio?

Re: WSJT-x 2.6.1 and uBitx on Raspberry Pi
#ubitx
It has to do wit this: The usb port resets when reopened by wsjtx, on arduino this resets the arduino and the ubitx loses track of what was going on.
I had mentioned this to the wsjtx guys but they didn't seem interested in fixing it. - f
Hi Dj,
I don¡¯t remember the exact issues I had when trying to upgrade but I ended up doing the same thing: reverted back to 2.5.4. ?
Cheers, Scott

Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
A 12V Zener might be well advised on the power line, and I bought a bunch anyway for the gates of the finals, but since my supply puts out 13.7V I wonder whether I should also put two or three regular diodes in series with it. I have seen the 5351¡¯s lm1117s fail twice, once simply shorting with smoke and simply dropping all power output to the 5351 and another time failing and sending 13.7v straight through to the 5351 which glowed orange in the chip¡¯s center before melting two pads, the latter which was fixed by removing and replacing it and the crystal oscillator with a 5351 breakout board. It¡¯s not as stable frequency wise but it¡¯ll do for now. I now protect the new lm1117 by putting a small 5V LDO 78L05 between the 13.7V rail and the new lm1117 which in turn provides the breakout board with 3.3V. The 5V supply to the 1117 also has a 47 uF electrolytic on its input. So far it works.
On the other hand the most recent failure did not involve the bitbanged I2C lines. Instead it involved the TX line output (GPIO4) failing to send a TX signal on PTT. Since this does not directly involve an lm1127 I have to assume that it failed because of a power surge from elsewhere, either a transient from the main power supply (in which case a 12 or 14V Zener on the main supply would be helpful) or else a higher voltage coming from rf somewhere. Either way if it¡¯s transient I doubt I¡¯ll be able to measure it when it happens. If there¡¯s no downside on putting 3.3V Zeners, with or without series resistors, on those three RPi lines, maybe it would help to do so. The right angle connector on the digital board has good exposure for adding small Zeners, and can easily be snapped open to insert a series 330 ohm resistor, and repaired if that interferes with the timing. Couldn¡¯t hurt to try, could it?

Ahh, ok.
I did not find the ver. of the first manual (I like the "hellov2 name, hi) so I asked.
Versioning of the .iso image is a must of course. Thanks for info and your help.

Petr, Git has in-built versioning but it auto generates the version names. I will mark the version with a more huma? friendly? names. We will host the iso image in another day. - f

many thanks for the Sbitx V2 manual posted on github.
As this document will be constantly revised to reflect the changes in the user interface, newer modes, etc. I suggest adding versioning of this document. It will be much easier to referring to correct version of manual.
Also, it would be really appreciated when the V2 image (.iso) will be available (to be burned to SD card for RPi) also have versioning of the code of course so that it is possible to keep an overview of individual versions and the most recent ones including changes.
Just my 2c suggestion :)

Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
The I2C lines on the raspberry pi can be blown in many ways: 1. The lm1117 of the si5351 shorts and puts 12v on the pins. 2.The lm1117 of the wm8731 shorts and puts 5v on the pins. 3. Si5351 or the wm8731 blow up and short the data/clock lines to ground. All these can only happen when the LM1117s blow out. It might be best to put a 12v zener on the powersupply line. - f

WSJT-x 2.6.1 and uBitx on Raspberry Pi
#ubitx
I'm running WSJT-X on a Raspberry Pi 4, 4Gb, running 32 bit "Raspbian GNU/Linux 11 (bullseye)" that is fully patched and up to date.
Radio is a uBitx v6.1 with a Signalink interface, using the Yaesu FT-817 settings in WSJT-X.
WSJT-X version 2.5.4 works fine, no errors.
Version 2.6.1 (installed with "dpkg -i wsjtx_2.6.1_armhf.deb") gives a hamlib Protocol error.
I've upgraded hamlib to version 4.5.4 as indicated by the WSJT-X release notes.
Downgrading back to 2.5.4 ("dpkg -i wsjtx_2.5.4_armhf.deb") and everything works fine again, even with hamlib 4.5.4 still installed.
Has anyone gotten WSJT-X 2.6.1 to work with the uBitx from a Raspberry Pi?
Thank you,
-Dj

We will maintain backward compatibility well into the future with the current version of hardware. This is good enough for us to do almost anything on HF. We have 25KHz of baseband bandwidth which is all we need. The rest is just clever software. - f

I seen a vid of a recently purchased ubitx with a nicer mic. It loos like the one in the sbitx. the guy in the vid had good drive and output without modding the rig or mic. Can I get that newer mic for my ubitx?

Re: Bring the BITX40 Kit or similar SSB transceiver kit back
Once you get it built and have used it for a while, report back and let us know what the performance is like. Thinking about getting one.
