No. That's what DSMX does and why it's superior to DSM2. DSM2 does NOT hop. New DX6i transmitters are DSMX, as is the new generation of receivers (AR6210 etc.)
All 2.4 spread spectrum radios need to be bound, whether frequency hopping or not. Binding is simply having the receiver learn the unique ID number of the transmitter (and model memory for ModelMatch radios) so it only responds to that one.
For standard systems, range is less a function of the transmitter than the receiver.
