person after redoing the circuit for the third time, I finally got the values ​​according to the scheme.
It wasn't pretty (kkkkkk)
but it works perfectly. I am really happy.
unfortunately I can't proceed with the transponder reading tests because I don't have a loop amplifier. I bought an mla30 and it still hasn't arrived.
Is it not possible to test without the correct amplifier?

thank you so much to everyone who helped me.

observation: my problem was definitely in the q5 circuit module but I'm not sure
