Nelle comunicazioni radio digitali, ed un tempo soprattutto in quelle telegrafiche, si usano spesso abbreviazioni delle parole più comuni.
E' un metodo, assieme al codice Q ed alla codifica numerica (ora in disuso, a parte il "73" e pochi altri), per rendere breve e soprattutto comprensibile una trasmissione.
Oltre alle definizioni standard, ve ne sono altre nate soprattutto tra i Radio Amatori, e di uso comune oggi.
