Establishing a Net
Full call signs are used when opening a net,
reopening a net, or reporting into a previously
established net. Proper control by the NCS and
adherence to operating rules by all stations within the
net enable the net to begin and maintain an exchange
of traffic with minimum delay. The NCS is also
responsible for maintaining security on its net.
Appropriate security guidance will be furnished by the
NCS to all stations prior to establishing a net.
Example:
When ready to establish a net, the NCS transmits:
Yankee One Six Charlie—THIS IS Mike One Five
Bravo—OVER
Each subordinate station then answers the call in
alphabetical order:
Mike One Five Bravo—THIS IS Alfa One Six
Two—OVER
Mike One Five Bravo—THIS IS Bravo One Nine
Eight—OVER
Mike One Five Bravo—THIS IS Delta Two Three
Four—OVER
Once the net has been established, it will normally
work with abbreviated procedures and call signs. The
NCS will, however, order the net to work full or with
abbreviated procedures or call signs, as required by
the conditions.
MESSAGES
A l t h o u g h R / T u s e s t h r e e m e s s a g e
forms—plaindress, abbreviated plaindress, and
codress—the form most used is the abbreviated
plaindress. However, the three parts are still used
(heading, text, ending).
The procedures for use of the above mentioned
messages are the same as for the use of the visual
message.
Plaindress
A plaindress message is one in which the
originator and addressee designators are indicated
externally of the text. It contains all components of the
basic message format (unless the call serves as the
address) and must always include the precedence and
date-time group. The group count will always be
included when the accounting symbol is used.
Abbreviated Plaindress
Operational requirements for speed and handling
may require abbreviations of plaindress headings. In
such cases, any or all of the following may be omitted:
Precedence
Date
Date-time group
Groupcount
Codress
A codress message is one in which the entire
address is encrypted within the text. The heading
contains only information necessary to enable
communications personnel to handle it properly.
Service Messages
Service and abbreviated service messages are
messages used between communications personnel
and pertain to any phase of traffic handling,
communication facilities, or circuit conditions. See
chapter 3 for more information concerning service
messages.
GENERAL OPERATING PROCEDURES
The procedures for conducting radio checks,
repetitions, cancellations, corrections, and
verifications are contained in ACP 125; take time to
study these procedures.
