I totally spaced that one! What that means is that in a way, the transmission is basically encripted with a sub-audible tone. When you transmit, that tone says to other radios "If you aren't set up to hear me(the tone) then you won't get the rest of the transmission". That way, only others in the group with the tone will hear you. And it is not hard to figure out the tone if you know the freq and don't hear anyone. Most radios have a tone search to figure it out.
Nice call, Brian!
