Ham Radio
A Ham Radio is an interactive item that allows the player to listen to radio broadcasts, including music stations, news reports, and military stations. As a ham radio is a two-way Radio, it can be used for distance communication in multiplayer games through text and voice chat, or simply to "throw your voice".
Usage
Although they can only be used stationary and when placed, ham radios require batteries to function and cannot function off house or generator power. They will spawn with a battery already installed, however having it turned on will drain its battery until it is consumed. Some radios can be found already turned on, these will have their batteries drained based off how long they have been turned on.
To use a ham radio, right-click it in the world and select "Device Options". This will open the radio control UI. Here you can see information about the radio's specifications and current settings, power it on or off, remove/replace the battery, adjust the volume, add headphones, mute the microphone, and select and edit preset frequencies.
Ham radios are two-way radios and will transmit and reproduce voices at a distance. This includes both the Shout command (default Q), chat messages, and voice chat (Default Lalt). Accidental transmission can be prevented by muting the microphone in the device options.
Noise received by a ham radio, either in text or voice form, will attract zombies. The range zombies will be attracted from depends on the type of ham radio and its volume setting. This can be avoided by using headphones.
Ham radios are particularly useful on multiplayer servers that have disabled global chat, and for those that enjoy role-play or more immersive game play. They are best set up at the players base to communicate with other players from long distances.
Ham radios can also listen to the Automated Emergency Broadcast System (AEBS) radio station, which is randomised every game. Once the player finds a radio with the AEBS present saved, they can then use it on any other radio. By listening to the AEBS the player can become aware of helicopter events and power shutoff.

Frequencies and Broadcasts
Most ham radios will be found with one or more preset frequencies, usually one of these local commercial stations:
Station name | Purpose |

101.2 MHz KnoxTalk Radio | Talk show, music. |
- The player can set any frequency they want and save it to their presens. They can then access the preset on any other radio.
- There are 'hidden' broadcasts on non-commercial frequencies, which include civilians noting military presence, and military broadcasts.
- Throughout the first week of the infection, news media and music stations will report on The Knox Event, and give the player outside information on world events, including riots, curfews being put into effect, and eventually, the breaking of the quarantine.
Types
Ham radios are one of the three types of communication devices.
- Consumer radios: Receive only, lightweight, commercial frequencies only.
- Walkie talkies: Short-range two-way, lightweight, more frequencies.
- Ham radios: Long-range two-way, exceedingly heavy, most or all frequencies. Earbuds cannot be used. Ham radios are best used as stationary furniture in a safe location.
