The schematics of the Audio Board (here i even have a PCB) and the Mainboard are finished:

You can find them in the downloads.

On the mainboard are the (HF-) Filters and mixers, furthermore the main MCU, which also creates the sin/cos clocks. The board has connectors for Power and Antenna.

On the Audio board are the most of the amplifiers, RX/TX switches and the (audio) low-pass filter. Here do you connect the microfone and the speaker.

Now i will design a PCB for the mainboard, and a PCB for the microfone...
