What is Traffic Handling? short messages (often less than 25

words) called radiograms often relayed (handled) by several

operators sent by amateur radio operators

via the National Traffic System (NTS)

sent accurately and efficiently

Benefits of Traffic Handling important during disasters develops good operating skills public service community outreach it’s fun!

The ARRL Radiogram - Address

AddressMore is better!

The ARRL Radiogram - Text

• use “X” instead of a period, “Query” instead of a question mark• each “X” counts as one word• a phone number in the text would count as three words

•example: 248 555 1234• closing (such as “Love” or “73”) is part of the text, not the

signature• don’t make the last word an “X”

Sending a Message (Phone) don’t say labels such as “priority”

and “station of origin” read at about half of normal

reading speed say “Break” and unkey immediately

before and after the text if the text is long, unkey during the

text to allow recipient to ask for fills

Sending a Message (Phone) Use prowords:

— “I spell”— “figures”— “initial”— “direction”— “operator’s note” (usually after the

message)

Sending a Message (Phone) Other prowords:

— “over”— “out”— “clear”— “roger”— “affirmative”— “negative”— “say again”

Sending a Message (Phone) when spelling, use ITU phonetics say “niner” for the number nine at the end of the message:

— say “End, no more”, or “End, one more”, etc.

— say your call sign

Receiving a Message (Phone) to ask for “fills”, say:

— “please say again, word after …”— “please say again, word before …”— “please say again, all between …”— “please confirm …”

compare the check to the number of words you copied

once you have copied the message successfully, say “I roger number …”

Numbered Radiograms

• condensed way of sending text• include “ARL” in check• in text, include “ARL” and the radiogram number,

spelled out• example: “ARL Forty Six”, which counts as 3 words

Delivering a Message by telephone, e-mail, US mail if delivering by phone, identify

yourself and say that you have a “greeting message” or “friendly message”

don’t say “X-ray” or “Query” expand ARL radiograms if you can’t deliver the message,

service it back

Servicing Back unable to forward or deliver in 48

hours handling instructions request

service back— HXB— HXC— HXD— HXE— HXG

Use ARL 67 with at least 2 fills
