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. 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

Re: V2 serial numbers
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

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

Re: About ATiny85 code
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!

Thanks Ashhar, there is what I thought. Btw, which "burner" do you use to write the firmware to the ATTiny85? Rafael

sBitx Developer¡¯s Edition (v1) ¡ª how to protect the RPi4?
A few of you are probably familiar with my experiences with the DE version of the sBitx. There have been quite a number of different things happening which, by Occam¡¯s razor, are in my opinion for

Re: sBIT 2 On-screen virtual keyboard
Gerald, Watch the MicroCenter website for Raspberry Pi's if you live near by you may be able to pick one up for a reasonable price. When they get PI's in stock the price is not inflated. A few

Re: About ATiny85 code
Ah, a good spot. I wanted to check how fast the adc works. If you see, the pin 5 is being flipped on each iteration of the loop. So, I connected the pin5 to an oscilloscope to measure the time

Re: Subitx ptt
Rafael, Exposing attin85 pins directly to external lines can be risky. It would be better to tie the tx_line (it goes high on transmit) to a 2n7000 gate and use the drain as an open / close ptt
