Digital Synthesis FM Transmitter

Fully functional prototypes

This FM transmitter project was started back in 1991 and completed sometime around 1993, long before IT Group was legally registered as a company in Romania. The original business idea was to target the east-European FM radio stations market which at that time was totally untapped, but the project eventually succumbed to the perennially corrupt Romanian bureaucracy (and, sure enough, Marconi, Philips and the likes happily seized the opportunity and hit the jackpot all over eastern Europe). Interestingly enough though, FM technology didn't really change at all since the early nineties (except only for the disappearance of the eastern-block OIRT standard), so the modules developed for this project remain technologically valid to this day.
