Packet and digital modes enable efficient data transmission over CB radio frequencies. These techniques, inherited from amateur radio, facilitate text messaging, image transmission, and automated communication, enhancing user interaction and operational capabilities within the Citizen Band spectrum.

Popular digital modes include PSK31 and SSTV, with resources like the SYMEK Packet-Radio homepage and DBO274 mailbox. Equipment often used includes sound card interfaces and software such as WinPSK, ensuring compatibility with various CB radios.
