Yes. It was first i had made

It turned out to be my own fail, i used jumpers instead of coils in BPF to speed up diagnostic and have not looking at scheme... and made REAL short.
Now it's fine, but lot of shame

What to do with this spike? It persist in receiving mode and transmitting as well, together with modulated signal always hearable tone. Like DDS frequency is leaking to transmit tract. Is it resolve with shielding (ecraning) PO* IC's?

Also, i'm not mistake with thoughts that BPF mapping in control circuit not match with software settings by default? Because when 40m diapason selected, not right relays are turned on.
