REGION, SECTION, and LOCAL
The four levels operate in an orderly time sequence to make a definite

Any licensed radio amateur with an interest
in traffic handling.
ARRL provides a standard form for all radiograms transmitted via the
NTS. This uniformity ensures that NTS operators can quickly
efficiently handle traffic.

the Station of Origin and never changed. Numbering is necessary because
hams may handle dozens of messages daily, and without a numbering
system it would be difficult to identify any given message.

STATION OF ORIGIN -
The call sign of the station originating (creating) the message.
- The number of words or word groups contained in the Body of the

consecutive characters with no interrupting spaces).
PLACE OF ORIGIN
- The location (city and state) of the party for whom the message was
created and not necessarily the location of the Station of Origin.

an inquiry about the health and welfare of an individual in

indicates “all is

traffic is cleared. The American Red Cross equivalent to an
incoming Welfare message is DWI (Disaster Welfare Inquiry).

voice (From the ARRL Public Service Manual)
Sample message for example:

KEY: “.” = word pause, “.. ” = group pause, “.. .. ” = copy pause, (//)
= release of PTT, (/.../)
required listening pause.
Prowords, operational words
and introductory words are shown lower case. Try sending the prowords and operational
words in a slightly higher pitched voice, the introductory words in a slightly lower pitched voice,
or vice versa. TX is the sender, RX the receiver, on a net frequency. (See STATION OPERATIONS for
details on off frequency calls.)
“W3RX ready to copy”. (In severe conditions the RX station may ask the

RX: “ROGER.. W3RX” (or “ROGER.. 73 W3RX”, etc.), or asks for fills, and
message when done.
TX: “W3TX” (or “THANKS 73 W3TX”, etc.); (The exchange is complete.)
* PTT releases (//) are not shown in this example. On fast VOX or PTT
operation, release or
listen after every group or phrase. The expected interruption pause
(/.../) is shown.
On FM repeaters, due to audio delays and receive site delays, it may be
impractical to break after groups without loss of audio.
In this case, the PTT switch is released only at the customary expected fill breaks. When
sending long messages or batches the receiving operator may be forced to say “go ahead” by
saying “over” at the break point between messages, thus confirming continuing good copy. Keep
the repeater transmission time limiter in mind also.
ICS-213 Message Format
ICS-213 message form is the standard format used by FEMA and
EmComm organizations. The General Message (ICS-
213) is used by incident dispatchers to record
incoming messages that cannot be orally transmitted to the intended
recipients. The ICS-213 is also used by Incident Command Post
and other incident personnel to transmit messages (e.g., resouce order,
incident name change, other ICS coordination issues, etc. to the
Incident Communications Center for transmission via radio or telephone
to the addressee. The form is used to send any message
or notification to incident personnel that require
The ICS-213 may be initiated by incident dispatchers and any other
personnel on an incident.
Distribution - Upon completion, the ICS-213 may be delivered to the
addressee and/or delivered to the incident Communication Center for
Another variation of this form is the ICS-213RR, which is specifically used for Resource Requests.
