Radiotele­type (RTTY — often pro­nounced “Rit­ty” ) is a ven­er­a­ble data com­mu­ni­ca­tion mode that remains in wide use today among radio ama­teurs. While RTTY does not sup­port the fea­tures of new­er com­put­er-based data modes, it is well suit­ed for key­board to-key­board chats with oth­er sta­tions. It is also the most pop­u­lar mode for world­wide dig­i­tal con­tests and remains in com­mon use among DXers and DXpe­di­tions. RTTY was orig­i­nal­ly designed for use with mechan­i­cal teleprint­ers, pre­dat­ing per­son­al com­put­ers by sev­er­al decades. Today, Ama­teur Radio RTTY uses sound­card-equipped com­put­ers and ded­i­cat­ed RTTY soft­ware.
