In radio communication, what is meant by “readability”?

Readability in radio communication refers specifically to the clarity and comprehensibility of a received signal. It assesses how well the transmitted message can be understood by the receiver, which is vital for effective communication. Factors that contribute to readability include the strength of the signal, the presence of interference, and the modulation of the transmission. A signal that is clear and easy to comprehend allows for accurate and effective exchanges of information, which is essential in radio operations, especially in critical contexts such as emergency communications or navigation.

The structure of the message, its volume level, and the frequency used for transmission are all important aspects of communication, but they do not directly pertain to the concept of readability. Structure relates to how the information is organized, volume pertains to the loudness of the sound, and frequency refers to the specific wavelength used for transmitting signals. However, none of these factors alone determine how clearly a message can be understood once received. Therefore, clarity and comprehensibility encapsulate the essence of readability in radio communications.
