DSM is Digital Spectrum Modulation—a purely digital RF link between transmitter and model that is based on Direct Sequencing Spread Spectrum technology. It operates within the ultra-high 2.4GHz worldwide ISM band, provides unequalled signal resolution, and is immune to the most common forms of RF interference. It will even allow a car to “talk” back to the user. It requires no crystals and completely frees racers from ever having to monitor frequency usage again. Best of all, with Spektrum’s DSM System racers can literally plug this phenomenal technology into existing transmitters like the JR R-1 and Airtronics M-8.
