FM Broadcasting from your computer

All about FM radio – Schematics, KITs, FM transmitters, digital transmitters and RDS encoders from PCS Electronics
From the site:
PCI MAX 2004 is a computer card that will change the way you listen to your MP3’s or other audio via PC. It will effectively change your PC into a FM radio station. You will be able to play your audio files (CD, wav, MP3, real audio etc.) from your PC through radio waves directly to your household radio receiver in the next room, in the living room, across your yard, in whole block of flats….or for the entire village/small city. I repeat, you need just an ordinary radio receiver to receive your signal. The included software (also available at the link below for a quick DL) lets you set the frequency and the output power. You can either service your living room, garden or an entire community. Get rid of these pesky cables!
