Hi Bob, Thanks very much for sharing these details, I would be very interested to know how you get on with the termination. Its a shame about the LTC6226/7, they...

This project doesn't cover broadcast FM radio. If that's what you need, you could checkout this project https://101-things.readthedocs.io/en/latest/fm_radio.html. It covers 87 to 108MHz out of the box so should work...

There is a bit of info on op-amp selection here: https://101-things.readthedocs.io/en/latest/breadboard_radio.html#operational-amplifier-alternatives. Basically you need less than 8nV/sqrt(Hz) noise voltage density and better than 10MHz gain bandwidth product. If you are...

There is something quite similar under the TFT branch, might be worth a quick look.

Yes, I've done a bit more development work in the TFT branch, it's not quite ready for another release yet though. I think we could take this PR as it...

I have been working on a ili9341 TFT waterfall, I've provisionally allocated allocated these pins. #define PIN_MISO 12 #define PIN_CS 13 #define PIN_SCK 14 #define PIN_MOSI 15 #define PIN_DC 11...

I'm quite keen to keep the spare ADC input as a mic input when I add TX capability. It will probably double as a morse paddle input too. Another option...

@Haranochi Thanks very much for sharing! It's a great build and I am so glad you were able to share it with your grandson. A perfect example of what this...

Sounds intriguing, perhaps you could tell us a little more about what you have in mind? Would storing those 4 frequencies in memories work?

There's a shortcut to the memory load function if you press the encoder, if you then put the 4 standard channels in memory you would have fairly quick access without...
