Nice FM Broadcast receiver

Nice small FM receiver (broadcast, 87.5 - 108 MHz) connected to speakers this morning and discovered it has a good sensitivity. 
Antenna: single wire of appr. 80 cm.

Allthough the receiver is designed to interface through a serial link to the outer world, it works fine as stand-alone unit. Power supply voltage 3.3V-5.5V.

Fun for a couple of euro's (You have to deliver your own speakers).
