All Unknown Signal & Radio Signal Amplifier Locations On Outbreak (All Regions)


In Outbreak, there are unique base radios that spawn randomly in fixed locations across all the regions. The spawn order is random, and the rate of spawn is very rare.

When you interact with the base radio, it spawns several zombies that you must eliminate in order for the base radio to emit a unique signal with a distinct sound. This signal is weak.

You must then find three signal amplifiers close to the base radio by interacting with them and matching the amplifier sound with the base radio signal. The base radio distinct sound library is a fixed set of signals, but you always get random sounds for each radio.

When you are near the amplifiers, you will hear a static sound effect. The static sound gets louder as you get closer to the amplifiers.

TOP GAMEPLAY HIGHLIGHTS

Once you match all three radio frequencies, you can return to the base radio and interact with it to listen to the full radio signal that spawns a lot of essence (points) and a unique classic song cassette from one of the old Call of Duty: Black Ops games.

There are a total of five songs you can get and they are as follows:

  • Abracadavre (Instrumental) by Kevin Sherwood
  • Alone by Kevin Sherwood
  • Amerika Infiltration by Brian Tuey & Jack Wall
  • Avogadro by Brian Tuey
  • Beauty of Annihilation (Instrumental) by Kevin Sherwood
  • Brave by Brian Tuey
  • Frequency by Brian Tuey
  • Generation by Brian Tuey
  • Lost by Kevin Sherwood
  • Lullaby for a Deadman (Instrumental) by Kevin Sherwood
  • Pareidolia (Instrumental) by Kevin Sherwood
  • The One (Instrumental) by Kevin Sherwood

Note that these song cassettes can spawn multiple times. This means you can get duplicates when interacting with the radios. You can access these songs using the Music Player feature in Black Ops Cold War.

Another important thing to keep in mind is that there is no minimum round for the radios to spawn. The radios can spawn at any difficulty level, whether it is difficulty level 1 or above. If you do not see the radio in any of the listed locations below, don't be discouraged. Continue progressing through the difficulty levels, and you will eventually find one. We had to skip 6 difficulty levels in one game to finally find one.

Another tip we have is simply checking for the locations in whatever region you spawn in and if you don't see radio in any one of the listed locations, restart the game.

The radio icon is not visible on the map until you are close enough.

The amplifier locations are not shown on the map even if you are close to them. This is where you use the static sound effect to find the amplifiers. Luckily for you, we've done the research. In this guide, we show you the locations of all the radios and the amplifiers in all the regions.

  1. On Duga, there is a third unknown signal in the chemical processing building. The main station is on the first floor of the large building. The amplifiers are all within the chemical processing fence boundary as follows:
    1) There are nine round things in a 3 x 3 rray - on top of the central southernmost one.
    2) There are thee round things on their own. Go to the top left corner of that platform.
    3) By the toxic pool, North east corner.

    1. Hi dz!

      Thanks a lot for your comment. We've updated the article with the third location!

    1. Hi Chloe!

      That radio is a Maxis radio which is part of the main outbreak easter egg. It is not the same as these unknown signal radios. You can tell they're different as the Maxis radio is not indicated on the map while these regular ones show up as an orange icon. We are currently working on getting the main easter egg guide out ASAP with all the locations and in-depth details!

  2. There is another unknown signal in golova . The corn fields by the bridge, there is a radio near the out houses on the south side of the field on a stack of pallets.

    1) to the west from the base signal, there is a shed, it is in the back left corner.

    2) on the east side of the field, there is another set of outhouses, next to the stacks of hay

    3) in the upper farmstead to the east of base signal, near the big hay baler, in the NW cement corner guard
