There is a great variety of ways that Amateur Radio operators are able to communicate. Using voice is just one. Morse code is still widely used. Packet, Radio Teletype (often called Ritty), and PSK are three more ways to communicate. Even faster transmissions are being developed using methods which can send almost any form of digital data. Hams also use television to send pictures over the air.
