Is the ussge of devo

Post SPI captures and/or send new models+tx to devs if you want new protocols (without any guaranty tho )
Some models with RF+MCU housed in the same IC are still hackable, I did a couple of them at the beginning of the year. Some are harder (eg Furybee F36).
I see an issue tho, more and more models are using LT8910/LT8920, these radio ICs are not supported by deviation and can't be emulated by another radio as easily as the xn297 with nrf24l01 for example (low baudrate, manchester or other encodings, arbitrary seed whitening ...)

Anyway, as you can see, the protocol development sub-forum is still active

Also, the list in the wiki is not up to date (partially my fault ...)
This spreadsheet has more models / protocols listed:
docs.google.com/spreadsheets/d/1nBHzT3VW...kHn1RIM84/edit#gid=0
But that's not fine, I agree everything should be in the wiki & manual ... Anyone with a bit of time in his hands for some secretary work ?

That's what a SDR does, but that's not that simple

No, that's not as simple as using a logic analyzer, quite a bit of work is required to demodulate the signal and to decode the packets.
