RTTY CW NR functions

[maurilored-stack]

read that you can decode Rtty and CW with a simple hardware jumper.
What do you think? Are you planning an implementation?
Could this modification also provide a noise reduction feature?
Thanks

NR is not possible (besides some Si47xx commands that aren't documented for Si4732 and likely don't work on it) because even if you do the jumper mod for audio in, there is no audio out from the CPU.

Regarding the RTTY/CW maybe later, when factory-made receivers with the integrated audio decoding mod will be available. We have an informal policy of only supporting stock hardware. Plus I have zero experience in DSP algorithms. I know @luarvique has a lot of experience in these matters, but I'm not sure whether he is interested in implementing the decoders.

Also I'd prefer to see a proper ADC chip integrated by a Chinese vendor into ATS-Mini instead of the simple wire mod. The built-in ADC doesn't work well with WiFi enabled 😞 (see #162)

And my personal preference is to use a smartphone as a portable digital decoder. Here's my setup #156 (comment)

Is there any way we can... nudge some Chinese vendor into making a few mods? From what I could gather reading the discussions, I2C RTC + external ADC + VFO stability mods would make for a neat upgrade from V3S and would unlock easy FW experimentation for those of us who are afraid of cutting traces and soldering tiny wires :)
