    This BA1404 FM stereo transmitter IC had such poor performance and many complaints that its manufacturer Rohm replaced it with an excellent line of ICs about 8 years ago. The newer ICs are used in most MP3 to car radio FM stereo transmitters made in the last 8 years.

    Silicon Chip magazine in Australia published The Micromitter project about 8 years ago (look for it in Google) and a company there sells it as a kit. It uses one of the new ICs, the BH1417.
