A radio is an interactive item added in build 33. It allows the player to listen to radio broadcasts, including music stations, talk-back stations, news reports, military stations and adverts. Unlike walkie talkies, radios are receive only. Most vehicles also include radio equipment, with civilian vehicles having basic radios whilst military or emergency service vehicles can have two-way-capable sets.

Usage

An example of the interactive radio interface.

All radios require batteries to function. They will spawn with a battery already installed, however, having the radio 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 radio, right-click it in the inventory or 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 earbuds or headphones, and select and edit preset frequencies.

Two-way radios will transmit and reproduce voices at a distance. While the radio can only receive and not transmit, the reproduction will be silent to nearby players and zombies if the receiving radio is using earbuds; otherwise, it will make noise in the environment depending on the volume setting. Bear in mind that only one radio in a given area will reproduce the voice, and if the person speaking is nearby, it will not reproduce it at all to prevent feedback. Radios farther away (generally beyond visual range) will still pick up and reproduce the voices.

Radios can also listen to the Automated Emergency Broadcast System (AEBS) radio station, which is randomized every game. Once the player finds a radio with the AEBS present saved, they can then use it on any other radio. Paired with earbuds, the player can then listen to the current weather, and possible helicopter event and power shutoff events stealthily while away from home.

Stationary or portable

Radios can be used either as stationary furniture, or as portable equipment. When portable, the radio must stay equipped in either the player's primary or secondary hand to be used.

Strategy

  • Place a radio in a preferred location, power it on, and tune it to the same frequency as your walkie talkie. Make sure it has no earbuds, and turn up the volume. *From a safe distance (within range), make noise using the shout command or voice chat.
  • Nearby zombies should converge on the receiving radio where you can evade them, shoot them, toss a Molotov, etc.

Frequencies and broadcasts

Most radios will be found with one or more preset frequencies, usually one of these local commercial stations:

Station name Purpose
89.4 MHz Hitz FM Music station.
93.2 MHz LBMW - Kentucky Radio News, music.
Random MHz Automated Emergency Broadcast System Weather, emergency.
98 MHz NNR Radio News station.
101.2 MHz KnoxTalk Radio Talk show, music.
  • There are also "hidden" broadcasts on non-commercial frequencies, which include civilians noting military presence, and military broadcasts. You are free to add presets for any frequency in the radio's spectrum.
  • 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.
  • Both scripted and non-scripted radio broadcasts will still occur after media blackout.
  • The frequency of the Automated Emergency Broadcast System varies each game. Radios with the frequency preset can be found in the world.

Disassembly

All radios can be dismantled with a screwdriver, producing a variety of components as well as 2 electrical skill XP.

The obtainable items are as follows:

Types

Radios are one of the three types of communication devices.

  • Consumer radios: Receive only, lightweight, commercial frequencies only. Consumer model radios serve as the radios installed in most (but not all) cars.
  • Walkie talkies: Short-range two-way, lightweight, more frequencies. Can be put in belt slots.
  • 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. Ham radios are quite rare, but can be found in vehicles that would require a two-way radio such as those used by emergency services; fire trucks, ambulances, police cars, and so on.

Radios come in a variety of styles and qualities. The range of available frequencies varies by model.
