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.

Radio Featured

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.

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.

Video Guide


There are three possible radio locations found in the Alpine region.

Radio 1

Base Radio

The first base radio is found at the Fire Aid Station. The radio is on a ledge on a small cliff leading up to the warehouse.

Amplifier 1

The first radio signal amplifier is inside the cabin, right in front of the base radio. It is the first cabin from the right side.

Amplifier 2

The second radio signal is by the main road north of the Fire Aid Station. The amplifier is behind stacked concrete blocks by the generator.

Amplifier 3

The final amplifier is inside the medevac warehouse on top of wooden crates.

Radio 2

Base Radio

The second base radio spawns by the fireplace at the hillside cabins.

Amplifier 1

The amplifier is at the patio of one of the smaller cabins located at the hillside cabin. It is the first cabin from the right side. Go around the back of the cabin, and you will find it on the table.

Amplifier 2

The second amplifier is inside one of the bigger cabins. You will find it inside the left side cabin on the first floor right after you've reached the top.

Amplifier 3

The third amplifier is found slightly west of the hillside cabins in a small shack.

Radio 3

Base Radio

The third base radio is found by the Frozen Lake at the Base Cabins.

Amplifier 1

The first amplifier is inside the hut just behind the frozen lake.

Amplifier 2

The second amplifier is found inside the second cabin from the left (out of the four cabins located next to the lake).

Amplifier 3

The final amplifier is found inside the northernmost small hut by the frozen lake.
