Why use simplex 2-Meter frequencies when a repeater will do just as well? Some reasons are unique to individual organizations; others are common to all. One reason is to get off a wide area channel when a simplex frequency will do. In public safety systems the repeater channel may be used for routine dispatch and communications, while a simplex channel is used only for the tactical and exclusive needs of the incident.
CA State OES began the Bulletins in the early 1950's to assist agencies and radio operators to become more familiar with RACES. They were issued periodically until 1985, at which time they began to be issued weekly over voice and digital radio systems of Amateur Radio and in print. Originally intended for California, increased demand, and a 1988 request by the ARRL for national distribution, led to their eventual worldwide distribution.
