The process whereby a receiver assimilated the GUID code of a transmitter. Once done the code remains with the receiver until it is bound with another transmitter. Once a receiver is bound to a transmitter there is no need to at any point re-bind it unless new failsafe settings need to be adopted.       This is a system of transmitting a radio signal to a receiver where rather than being fixed onto one channel it hops from one channel to another constantly, using a random sequence. In short the transmitter sends a stream of control data at the end of which there is a code that tells the receiver which frequency to hop to next. It does this hundreds of times a second and so the chances of any type of interference are virtually nil; if two devices did end up during their sequences on the same frequency at one time it would only be for milliseconds so you simply wouldn’t detect it. Unfortunately there are two big drawbacks for FHSS with regard to using it for models. Firstly the latency (response time). Ideally we want it to be zero but practically it tends to be around five milliseconds for most conventional radio systems. Some a quicker, some slower but FHSS at best has proven to be around twenty five milliseconds but more generally around fifty. Secondly is its response to interference. Should there be a break in signal it can take from two to four seconds for the transmitter and receiver to re-synchronise and this clearly when controlling a plane, helicopter or car traveling at speed is unacceptable.       This is the system used by Spektrum®. DSSS is unlike any other system we have had before in that it is aware of what is going on around it. When turned on a transmitter scans to find one of the eighty channels that is not being used, locks on and occupies it and then starts to transmit its GUID code. While this has been happening the receiver had been scanning the bands also looking for it’s transmitter GUID. When it detects it the two lock together to form a solid RF link. Once functioning the data transmitted is actually spread across the complete bandwidth using a random noise code, which has the effect of digitally increasing the range of the equipment. The receiver is aware of its transmitters spreading code and can distinguish its intended signal.
