I am really trying to get a decent wireless system with my arduino + amateur radio. I found this IC that decodes FSK signals, and was wondering if it could help me with decoding AFSK 1200baud signals. The IC is the NJM2211. I have no idea how the IC works, how to get it timed correctly, or what it outputs out of that pin.

Should I go this direction? Would this IC help me?

Do I see an avr ic on that thing? Wish they'd just release the code for it... Would really love to see how they pulled it off cleanly. – Kyle Feb 25 '12 at 6:02

Actually you can decode the signals in software using the Arduino. See Arduino TNC.

The software to do this is open source, BeRTOS.

Here is the hardware interface:
