What is the main difference between the Spektrum system and Futabas FASST system?
The Spektrum systems utilize what is known as Direct Sequence Spread Spectrum modulation, or DSSS. Using this methodology, the system selects a channel, or channels, and remains on this frequency indefinitely. Futaba’s almost 15 years of experience with spread spectrum technology has proven that the ideal situation for modelers is to utilize channel shifting whereby the system continuously changes frequencies every two milliseconds thus preventing signal conflicts and eliminating interference issues.
