4.Three Basic Radio Etiquette Rules
(1)The international radio language is English, except in cases where you are licensed
to speak in some other language.
(2)When using a two-way radio you cannot speak and listen at the same time, as you can
with a phone.
(3)Don't interrupt if you hear other people talking. Wait until their conversation is finished
unless it is an emergency. If it is an emergency, inform the other parties that you have a
urgent emergency message (see "Emergency Calls" below).
