zbitx schematic and pcb xray

 

Folks,
Here is the schematic of the first version of zbitx. I already know that some things have to move on the?PCB(the raspberry pi pins are inverted!). The micrcontroller?is changed from the ATTINY to a Raspberry Pico. But the rest are all the same!
- f?

Thanks Farhan,

Would there be a possibility of the signal levels in Vpp at T2 on pins
5,2 and 6,1 too please? Is T1 9 turns - on FT37-50? I might have
missed this information somewhere if published already.
Again would signal levels at QJ1 and QJ7 be available please?

Best 73,

Retrying,
Is there any voltage analysis not DC, Signal levels. What to expect at each stage.

Thanks.
