And one question from me - wouldn't it be better to move "CH1" and
"CH2" label to outside of the boxes? If we decide to put actual EMI
shields, labels will be hidden.

Hi all.
Here zip with all project files include PDF and BOM for GSM900 assembly
variant.
PCB and Gerber will be in the next letter.

I think to use 550mhz in case of 360 mhz IF.
So image will be around 190 mhz, but here also there are very strong TV
and trank radios.
Best regards,
Andrey Sviyazov.
