What about an AM/FM/SW radio breakout board?

Silicon Labs [Si4735 is a complete AM/FM stereo/shortwave/longwave radio receiver with analog and digital audio outputs. It is a software-defined radio (SDR) and has RF amp, PLL, A/D, DSP, D/A etc. with I2C interface. Microsoft Zune uses Si470x series. It looks like a neat chip, time for pirate radio :wink: Covers 64-108MHz, 153-279kHz, 520-1710kHz, 2.3-21.85MHz bands. North American Radio Broadcast Data System (RBDS) too; the Si4737 enables broadcast data such as station identification and song name to be displayed to the user.

20 pin QFN 3mmX3mm package, too small for manual placement.

I saw the Si4735 in Elektor magazine 02-2010 project and it looked great, very simple hardware- a 3.3V reg, LC antenna, a few caps and a 32kHz clock input.](Infrastructure and Automotive - Divested Products - Silicon Labs)

Iā€™d like to see this also on a breakout.

You mean like this one? http://store.curiousinventor.com/blog/FM_Radio_RDS_Vid/ I have one in my hands as we speak. Very cool stuff and Arduino compatible!

That looks like a Si4701 (FM only) design with a bunch of extra chips, not sure what they are for. Not bad for $30.
