ARRL Numbered Radiogram
An ARRL Numbered Radiogram is a brevity code used in composing ARRL Radiograms during times of radio congestion. The code is used to transmit standard messages, sometimes with customized text, very quickly by experienced ARRL National Traffic System (NTS) message traffic handlers. In use, ARRL Numbered Radiograms are messages encoded as one or two numbers. The numbers are always written down as words, and are always preceded by the procedure word "ARL". Throughout their transit in the Amateur radio National Traffic System, they retain this format and are only expanded to their plain-English meaning when delivered by a Ham. For example, "ARL FORTY-SIX" would be typed in a letter or spoken over the phone to the addressee as "Greetings on your birthday and best wishes for many more to come." For those codes where customized text can be added, the customized text is added immediately following the number code word. For example, "ARL SIXTY TWO CHRISTMAS" is expanded upon delivery outsid ...

ARRL Radiogram
An ARRL radiogram is an instance of formal written message traffic routed by a network of amateur radio operators through traffic nets, called the National Traffic System (NTS). It is a plaintext message, along with relevant metadata (headers), that is placed into a traffic net by an amateur radio operator. Each radiogram is relayed, possibly through one or more other amateur radio operators, to a radio operator who volunteers to deliver the radiogram content to its destination. Form overview Radiogram forms facilitate a standard protocol between amateur radio operators, allowing much faster relay of formal messages. They do this by always having the message headers in a certain order, allowing operators to read and understand the headers without explicit verbal labels. This is especially important in hectic and stressful environments such as during a disaster, when many parties call upon radio operators to quickly transfer messages in and out of the affected areas. A typic ...

National Traffic System
The National Traffic System (NTS) is an organized network of amateur radio operators sponsored by the American Radio Relay League for the purpose of relaying messages throughout the U.S. and Canada. During normal times, these messages are routine greetings ("Happy birthday Aunt Mary") and keep the system well oiled and the operators trained so that everything works when needed. When there is an emergency or disaster NTS works closely with the Amateur Radio Emergency Service to provide emergency communications. The most common type of disaster-related messages are "health and welfare" inquiries and notifications into and out of the area affected by the disaster. In time of disaster, it is easy to expand the system by simply creating additional meeting times for the nets with high volume, or by setting up a specific "trunk line" between two points. History Traffic passing by formal relay (via amateur radio) originates from the founding of the American Radio Relay League. The NT ...

Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communications. The term "amateur" is used to specify "a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;" (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and ''amateur-satellite service'') is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station licenses with a unique identifying call sign, which m ...
