So.... NFC work now.... This mean im 125KHZ Rfid from complete F0
THE BUILD PRICE IS ARROUND 20 EURO NOW, and all what is left is 125khz RFID. Sure, i will need to learn some analog, but should be easy, right?
I just dont like abstraction...
anyway...
Now, it seems to transmit on right frequncy, BUT, i need top calibrate my cheeap RTL-SDR, to be really sure...

SubGhz tests and optimization.
Today, s decided to test the SubGhz module on my (currently 15 USD) DIY Flipper zero.
As you can see, i find out, that transmision is happening on 433.88, instead of 433.92, and i believe, that it is caused by crysal on cheap chinesse module, so i decided to to find a way how to fix this in the FW.
