Typically, radio station hosts will mention a keyword and an SMS short code—a 5 to 6-digit number—or phone number on-air that listeners can text to. For example, a listener might text the word “SONG” to the short code 12345 to make a song request.

The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and 'decodes' it back to the desired form: sounds, images, data, etc.

When a text message is written, it is transmitted as binary code using a particular frequency of radio waves specific to that user. The signal is received by a nearby cell tower, which then directs the information to be transmitted by another tower near the intended recipient.

On more advanced radios, you can send or receive dozens of pre-programmed messages – useful for situations that occur frequently; this saves your team time on the keypad and increases productivity. Higher end two way radios also let you create and send new text messages on the fly, much as you'd do on a mobile phone.

What is Radio Text Messaging? This is a service that allows listeners to request songs, enter contests, receive important updates, or simply interact with the station. Typically, radio station hosts will mention a keyword and an SMS short code—a 5 to 6-digit number—or phone number on-air that listeners can text to.

In order to transmit data via a radio link, the data, which is typically presented to the radio in a digital format (i.e. 1's and 0's), has to be converted to an analog, voice-like signal. This process is reversed on the receive end. The circuitry that performs this conversion is called a modem.

It is possible for text to be sent over an AM or FM signal. Ham radio operators use morse, or more modern alternatives, such as packet radio. Commercial fm radio stations transmit RDS (Radio Data System). TV stations used to transmit teletext, although that practice had largely stopped.
