Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
Gordon,
I have the time and have done some forensics on other devices.? I am NOT a Raspberry Pi expert.? I DO have the SMD tools that I need.
With the above understanding, I would like to look

No worries my friend.? Glad you are doing some final checks on the software of the radios.? It gets here when it gets here.? Will have some time this summer to tinker with the software.?

John,
Trying the 3.3 volt (maybe 3.6 volt?)? with or without the resistor could not hurt.? The diode would add capacitance that might make the I2C decode an issue, so I would do the Zener first,

Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
Mark,
If you monitor the current draw of sbitx, it is well under 1A on receive.
There is no way the rpi can draw more.
There is some other reason, not low voltage. The low voltage warning

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

Re: WSJT-x 2.6.1 and uBitx on Raspberry Pi

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

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.

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

Re: Sbitx manual
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.

Re: Sbitx manual
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.

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

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

Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
I don't know how my two RPi 4's were destroyed but neither will even boot
now. I suspect RF on the power pins. The power measured fine on a DC
voltmeter. I have not been able yet to recover

Re: sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
Evan, since I have two RPi4s with damaged SDA and SCL GPIO pins and another with a damaged GPIO4 (TX) pin I think I should put 3.3 volt Zeners on those lines, with series 330 ohm resistors. I assume

We will maintain backward compatibility well into the future with the
