SiLabs Chip Add-on for Arduino Boards

Saw this on a YG I belong to, and thought it may be of interest to some:

radio on a chip

I've been playing with Arduino microprocessing boards lately, making 
LEDs blink, that sort of thing. One thing I've been trying (and failing) 
to do is to use an Arduino to build a radio around the Si4735 
radio-on-a-chip from Silicon Labs. I was on the site of Sparkfun 
Electronics last night and noticed that they've created a shield (in 
Arduino language, that's an add-on board that piggybacks on top of the 
Arduino board) with an Si4735 on it. So I ordered one.

The chip is roughly the same one used in some of the most recent 
ultralight radios from companies like Degen and Tecsun. It has a 
surprising number of features, like multiple filters from 1kHz to 6kHz.

I hope to have the board sometime next week. I'll let you know what I 
think of it once I get it running.
