Hi Tim, The spektrum radio operates on the 2.4ghz band. The way that there is never any interference is that the radio is essentially trasmitting on two frequencies at once in the 2.4 ghz band. The reciever is recieving both frequiencies. If the radio detects a problem on one of them, it will change in flight. Basically the system is constantly changing so that you never have glitches or interference from other modelers. but since there are no set channels, each reciever has to be "binded" to your tx only. all the rx's can be reset and rebinded when ever you want, but the system is great! I used to fly PCM and the Spektrum radio is actually a little bit faster than PCM. I hope that makes sense. simply put, it is a kick a** radio!
