Sounds like multiple communication streams simultaneous transmitted on one
signal. The signal is an RF term. Audio tones - however many there are in the
RF Signal bandwidth employed - are not separate signals.
The rules should be clinical on this issue if they expect people to follow it.

Well it could be considered seperate signals, but actually what is beig
transmitted is three tone sets on one signal. The receivers on the other end
decode them as 3 seperate signals because that is what the audio sounds like.
And the remark about the operator doing a good job of handling the simultaneous
contacts should mention the computer and the programmer instead. It is all
basically automatic.
