OPENING THE NET
The responsibility for opening the net for the first
time or reopening the net after it has been temporarily
secured belongs to Key. To accomplish this on a free
net, Key would transmit:
Poseidon, THIS IS Key, OVER.
After the transmission, all stations answer in
alphabetical order:
Key, THIS IS Kamehameha, OVER,
Key, THIS IS Polk, OVER, (and so on until all
stations have responded).
After all stations on the net have answered, Key then
sends:
Poseidon, THIS IS Key, OUT.
This last message from Key informs all stations that
their transmissions were heard and there is no traffic for
them at the time.
If a station does not reply to the collective call
within 5 seconds, the next station answers in proper
sequence. Barring any difficulties the station may have,
the delinquent station answers last. If the delinquent
station is having difficulty that prevents an answer to the
call, it reports in to the net as soon as possible with the
transmission:
Key, THIS IS (name of station).
Reporting In To Net, OVER.
At this time on the free net, and following a
preliminary call, the stations concerned would start
transmitting traffic to each other. For example, if
Vallejo has traffic for Kamehameha, it would let
Kamehameha know this with the call:
Kamehameha, THIS IS Vallejo, OVER.
Kamehameha would acknowledge with:
Vallejo, THIS IS Kamehameha, OVER.
Vallejo would then send its traffic.
On the directed net, when all communications over
the net are controlled by the NECOS, Key would call the
member stations and announce that the net is directed.
In this initial transmission, Key would request
information on the status of any outstanding messages.
For example:
Poseidon, THIS IS Key, This Is A Directed Net, Of
What Precedence And For Whom Are Your
Messages, OVER.
2-16
Each subordinate station then answers in
alphabetical order, indicating its traffic on hand. For
example:
Key, THIS IS Polk, I Have One IMMEDIATE And
One PRIORITY For You, OVER.
Key, THIS IS Vallejo, No Traffic, OVER. (Other
stations respond.)
After all stations have checked into the net, Key
would ROGER for the transmissions and commence to
clear traffic in the order of priority. For example:
Poseidon, THIS IS Key, ROGER, Polk Send Your
IMMEDIATE, OVER.
After Polk has sent its transmission and obtained a
receipt, net control then gives permission to transmit to
the station with the next higher precedence traffic.
After the initial traffic is cleared, stations having
messages to transmit to other stations on the net must
first obtain permission from net control. For example:
Key, THIS IS Tecumseh, I Have One ROUTINE
For Polk, OVER.
Net control then answers:
THIS IS Key, Send Your Message, OVER.
As you can see from our examples, circuit
discipline is essential. Regardless of whether a single
ship is entering port or several ships are engaged in a
major fleet exercise, voice communications are
required. The number of necessary circuits and nets
increases with the complexity of the task and the
number of units participating.
Whether the net is free or directed, the Net Control
Station has the primary responsibility for expediting
message traffic. Each station is responsible for assisting
net control in the proper passing of traffic. Adherence to
proper operating procedures and communications
standards is essential in keeping a net free of backlogs
and tie-ups.
ESTABLISHING COMMUNICATIONS
We have already discussed the procedure for calling
and answering on free and directed nets. There will also
be times when you will need to establish
communications with a ship or station on a temporary
basis to pass message traffic. This consists of nothing
more than a simple call-up to initiate contact and to
determine whether communications conditions are
good. For example, if the USS Ohio wants to contact
