-====== Digital modes ======
-Digital modes encode information so a receiver or computer can decode it. They range from keyboard conversations to packet networks, image transmission and short weak-signal messages.
-===== A typical station =====
-Many computer-assisted modes use a transceiver, a computer and an audio or data interface. Important setup details include audio levels, transmit control, frequency settings and the time synchronisation required by the selected mode.
-===== Examples =====
-  * **FT8 and FT4:** structured, short-message modes provided by WSJT-X.
-  * **WSPR:** weak-signal beacon reporting, used to observe propagation paths.
-  * **RTTY and PSK:** families of keyboard communication modes.
-  * **Packet radio:** data communication organised into packets, used for several amateur applications.
-Digital modes have different purposes and operating conventions. Document the exact software version, settings and mode when describing a result.
