DSS -vs- FHSS
 

So what's the difference? Will a DSS Rx from an M11 work with an FHSS MX3 Tx or vice versa?

So just to clarify for myself.....as of right now, the only Rx for DSM that can be swapped from Tx to Tx are the spectrum and Losi DSM units....eh?

DSSS and FHSS are totally incompatible technologies and will not work from one to the other. Below is straight from the Spektrum Site:

There are two main broadcast methods that spread spectrum manufacturers can utilize. One format is Frequency Hopping Spread Spectrum (FHSS). With an FHSS system, the transmitter transmits a narrow band signal and rapidly jumps from one frequency to the next, spending a few milliseconds on each frequency. Originally, Spektrum engineers started their development with FHSS-based systems because they were relatively easy and inexpensive to develop. However, they soon discovered that FHSS had several limitations that would prevent it from being the optimal solution for RC. While more difficult and costly to develop, our engineers began experimenting with Direct Sequence Spread Spectrum (DSSS) and optimized the modulation scheme to overcome critical response and re-link issues. DSSS systems transmit on a single selected frequency but on a very wide band. Only a small portion of that band is used for specially encoded information. In addition, DSSS offers an increase of processing gain for significant improvements in range. With years of development and testing, the DSSS modulation scheme was optimized for RC car and airplane use, and Spektrum´s DSM 2.4GHz Spread Spectrum Technology was born. DSSS provided engineers and hobbyists with the safety, security, and locked-in feeling that is necessary to maintain total and complete control in any vehicle or aircraft.

Thank you very much.;)
