The following radio operator guidelines are recommended for observing
security practices and precautions. They may reduce the possibility
of security leaks during radio transmissions.
Many of these
guidelines also apply to wire communications.
Besides radio operators, you must also ensure that switchboard
operators, telephone operators, and telephone users adhere to the
following guidelines:
Don't violate radio silence.
Don't transmit in a directed net without permission.
Don't make
unnecessary
transmissions,
such
as
excessive
testing.
Don't transmit faster than they can receive.
Don't use more transmitting power than necessary.
Don't tune transmitters with antennas connected.
Don't use excessive time to tune, change frequency, or adjust
equipment.
Transmit all messages by the most secure means available.
Use prescribed radio-telephone procedures to transmit clear
text messages by voice radio.
Preplan the
wording
and
content
of
all
messages
to
be
transmitted.
Use prescribed authentication
systems
and
eliminate
all
unnecessary transmissions.
Carefully consider replies before answering inquiries received
by radio.
This reduces the possibility of a slip of the
tongue which may give out information that may aid the enemy.
Practice and maintain a high standard of net discipline at all
times.
Use message books in preparing messages for transmission.
This
practice,
in
addition
to
aiding
and
improving
communications security, will provide a record of messages for
later reference.
