Radio and Morse code between bunkers
Two years after the blackout the radio is the only thread that connects you to other survivors. Listen, tune in and answer in Morse code.
The bunker radio
The radio in the main room has two tabs: the music speaker, with the tracks you get in the warehouse, and the broadcasts, with news, clues and messages of hope aired at server times.
The shortwave transmitter
To transmit you need to build the shortwave transmitter in the workshop, with the control room open. Every bunker has a unique frequency; with the transmitter you can sweep the band to discover other bunkers or tune a specific frequency.
Talking in Morse
Messages are sent in Morse code. There are fixed phrases for everyone and, from level 12, free text of up to 40 characters. There are limits on messages per hour and per day, and you can report or block anyone who bothers you.
