New tech from Spektrum
February 3, 2011
Horizon Hobby and Spektrum announced on Thursday a new “frequency-agile” 2.4GHz radio system called DSMX.
DSMX is based on the same wide-band 2.4GHz DSSS (Direct-Sequence Spread Spectrum) technology used in Spektrum’s popular DSM2 transmitters. However, the DSMX transmitters will use an algorithm to shift frequencies, affording fliers better connectivity to their radio-control vehicle in environments where the 2.4GHz bandwidth may be saturated.
According to a release, the new DSMX radios use a GUID (Globally Unique Identifier) that shifts the frequency pattern throughout the 23-channel 2.4GHz spectrum in a way that is unique to each individual radio.
Spektrum says that the new radios are geared toward hobbyists who often find themselves at events with a hundred or more other fliers, where the bandwidth can get used up pretty fast. DSMX radios are backward compatible with DSM2 receivers, and DSM2 receivers are compatible with DSMX radios.
A DSMX add-on is available for all DSM2 radios from Horizon Hobby for $75. The DX8 radio’s firmware can be updated by a download from Spektrum.
