The first 10-15 seconds of human contact is far more critical than many of us realize. In the first few seconds that someone sees us [either face-to-face or across a room] an involuntary assessment is made. If that assessment is unfavorable, then - unless the person is skilled at looking beyond appearances - it can be difficult or even impossible to overcome that by later action. It is recognition of such an evaluation that some communications reserve units require uniforms.
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.
