They don’t have to be in the air! Just take something like the Joe
Nall event for example. No frequency pins for DSS. It would be VERY
easy to have 40 systems on at the same time! Some playing with foamies,
some adjusting models and some getting ready to fly. You could be at the
flight line to fly, turn on and find that the system will not operate because all
the 2.4 channels are in use! That is why there needs to be frequency pins
for DSS and you should not turn them on when you are not in possession of a
pin. No, you won’t cause a crash, but you could fill up the band!<o:p></o:p></span></font></p>

80 frequencies. Each Spektrum unit picks two unused frequencies and
transmits on both. 80/2=40 transmitters that can operate at once.
It is a requirement of the FCC that things on this band don't interfere with
each other, and transmitter power is strictly regulated, therefore anything
using the band has to check before transmitting. You have no idea which
two frequencies you are on (nor do you care), as they change each time the
transmitter turns on.<o:p></o:p></span></font></p>
