DSM

Abbreviation for "Digital Spread Modulation". Spektrum RC, a division of Horizon Hobby, created this term to set their radios apart from others. 2.4GHz radios that use DSM technology (Spektrum), are really using a technology called DSS (Digital Spread Spectrum), which is used by companies such as Spektrum and Nomadio. Cell phones and pagers also use this technology.
