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

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

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

Thanks Ashhar, I have the Baofeng speaker mic and I need to shout a little to get any output, Maybe I just have a dud.I would still Like a different mic Jeff KA8SBI

The sbitx quick manual is on github.com. https://github.com/afarhan/sbitx/blob/main/hellov2.pdf

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

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

Jeff, It just looks good, frankly. It has the same panasonic element inside it. Don't fall for the HF Signals sales pitch :-D - f [email protected]> wrote:

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

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. Max KG4PID

I just receive Sunil's Easy Bitx kit in the mail today.? It exceeds my expectations.? The kitting and packaging alone is worth the cost of the kit.? Sunil has a great manual on his site and the

Farhan, I hope that you are working on new version of software only / refactoring code …not on new version of hardware platform, hihi. - P

Darrell, We have tested the radio long enough. The best thing about the SDR is that it is all in software. I am already working on the next version, refactoring the code. The boxes will be picked up

Re: sBitx V2 Question About Frequency Readout Display I saw a picture of the new sBitx V2 and the Frequency Display looks really small. Does anyone know what the approximate size of the frequency

Thanks Evan. 3.3v zeners did occur to me, ?Incidentally I did have Zeners across the finals and still one of them shorted. It’s strange. Jack N6LN

John, I have been thinking along the same lines to protect the most expensive component in the sBITX.? Here is what I found in a search on the

Hello Ashhar: I agree with the other gentlemen.? Do not rush and make mistakes.? Instead, take your time.? A good radio is well worth the wait.? And I get to be on the ground floor of Version

Sorry to come back to this topic again, but the pin 5 is not the I2C SDA? This LOW/HIGH changes would not create some noise in the I2C communication? I created a PR removing such

No problem, there are also "off-the-shelf" ones. I'll choose one and test. tks!

I built one with an Arduino nano, a 10uf cap and two resistors. Not sure where I saw the circuit diagram. - f
