How to Change Radio Frequency in Arma Reforger

Communication is a core survival skill in Arma Reforger. Whether you're coordinating a squad assault, calling in a resupply, or syncing up with another fireteam across the map, radio frequency management determines whether your team communicates or operates in silence. Knowing how to change your radio frequency — and when — is one of those fundamentals that separates coordinated play from chaos.

What Radio Frequencies Are in Arma Reforger

Arma Reforger uses a simulated radio communication system built around the AN/PRC-68 and similar military-style radio equipment modeled in the game. Each radio operates on a specific frequency measured in MHz (megahertz), and players can only communicate with others tuned to the same frequency.

This isn't a simplified push-to-talk system like many other military shooters. The frequency system is deliberate and tactical. If your squad is split across two frequencies, you won't hear each other — full stop. Getting this right is as important as any loadout decision.

How to Access Your Radio and Change the Frequency

Here's the step-by-step process for changing your radio frequency in Arma Reforger:

1. Equip or access your radio — You need a radio in your inventory. Depending on your role or loadout, this may already be issued to you, or you may need to pick one up from a supply point or fallen player.

2. Open the action menu — By default, press and hold B (on PC) to bring up the interaction/action menu. Console players will use the equivalent hold action on their controller.

3. Select the radio — From the action menu, interact with your equipped radio to bring up its interface.

4. Adjust the frequency — Inside the radio interface, you'll see a numerical frequency display. Use the scroll wheel or directional inputs to dial the frequency up or down. Frequencies are adjusted incrementally, so take care to land on the exact value your team is using.

5. Confirm and close — Once the frequency is set, close the interface. You're now transmitting and receiving on that channel.

🎙️ Important: Both parties must be on the identical frequency. Even a 0.1 MHz difference means no communication.

Short-Range vs. Long-Range Radios

Not all radios in Arma Reforger work the same way, and the type of radio you carry determines your communication range — not just your frequency.

Short-range radios are standard infantry issue and work well for squad coordination within the same area of operations. Long-range radios are typically carried by squad leaders, commanders, or designated radio operators and are essential for coordinating between separate elements of a larger force.

The frequency-changing process is the same across both types, but long-range radios often require a second player to carry the backpack unit, adding a real-world logistics layer to radio management.

Frequency Conventions in Organized Play

In public servers and pickup games, frequency management is often informal. Players might pick a frequency at mission start and stick with it. In organized or milsim communities, frequency discipline becomes far more structured:

• Command nets operate on one frequency
• Logistics or support channels run on another
• Squad-level comms use separate dedicated frequencies
• Encryption or frequency hopping may be simulated through agreed protocols

If you're playing in an organized unit or on a server with strict communication protocols, frequency assignments are usually given in a briefing or through your unit's documentation before the mission begins. Showing up on the wrong frequency is the radio equivalent of walking into the wrong briefing room.

Common Problems When Changing Frequencies

Even when players know the process, a few recurring issues cause confusion:

• Slight frequency mismatch — Double-check the exact value. 46.0 and 46.1 are not the same channel.
• Wrong radio selected — If you're carrying both a short-range and long-range radio, make sure you're adjusting the right one.
• No radio equipped — Some roles don't spawn with a radio. Check your gear before assuming the problem is frequency-related.
• Mod conflicts — On modded servers, radio behavior and frequency ranges may differ from the base game. Some mods extend frequency ranges or add entirely new radio systems.

🔧 If you can hear yourself transmit but no one responds, frequency mismatch is almost always the cause.

What Affects Your Experience With Arma Reforger's Radio System

Several variables shape how the radio system feels and functions in practice:

• Server rules and mods — Vanilla Arma Reforger has one system; heavily modded servers running frameworks like ACE or custom communication mods may introduce entirely different radio mechanics, UIs, and frequency ranges.
• Your role in the squad — A rifleman rarely manages frequencies; a squad leader or radio telephone operator (RTO) handles comms for the group.
• Game mode — Conflict mode and scenario-based missions may have different communication expectations and pre-assigned frequency structures.
• Platform — PC players using keyboard and mouse interact with the radio interface differently than controller users, which can affect how quickly frequency changes are made under pressure.

Understanding the base mechanics gives you a foundation, but how you apply frequency management depends heavily on the server environment, your role, and how seriously the group you're playing with treats communication discipline. 📡
