No,
It is one highway (the 2.4 spectrum), with multiple lanes. Where is this information coming from? This is completely backward from what I have read up to this point. If you look at a spectrum analysis of the 2.4 ghz band with a DSS system, you will see that it picks two channels or lanes at power up of the Tx, and will not move from those two lanes as long as you leave the Tx up. The last link I posted showed that at some times the Spektrum/JR Tx will pick two channels that are directly adjacent to each other in the spectrum. Thus, if the high powered 2.4 Tx that is dumb (doesn't look out for other things on the band) it can blanket these two adjacent bands and cause a lock out. Bruce showed this on his site. It is not like it will now move over to another lane or channel.

It's not like we have 2 dimensions to play in here, we don't even have two spectrums. Once a pair of channels or frequencies is chosen, they are that way until you power cycle the Tx.
