Dear Alexandr:
I searched all over the world and I couldn't find the PCAD 8.7.
Can you save the board in other format? Protel is OK.
Or may be you can send me the layers of PCB in format RS274X.
You has done a big work with the design of the tranmitter and I want to build mine.
Best regards
Alfonso from Argentina
I'm sorry - I don't sell transmitters or other stuff. You can build one - use my circuit and CPU firmware.
