Hi,

I have created a evaluation board for the Si4732 + ATMEGA328P so that 
the Si4732 can be used as a general purpose IF processor (typically 10.7 
MHz or 21.4 MHz) for decoding AM/SSB. See excellent library by PU2CLR on 
the internet for controlling the Si4732/Si4735. I have achieved 
excellent results with AM demodulation.

Attaching gerber files.

Upload gerbers to aisler.net to order PCBs.
