Frequency Modulation Boxes in ARC Raiders – Where to Find Them and How to Farm Them Safely

If you are pushing deeper into ARC Raiders and working through your Expedition Project, chances are you have already hit the same wall a lot of players are running into right now. Everything is moving smoothly, your crafting is on track, and then suddenly the game asks for Frequency Modulation Boxes.

And just like that, progress grinds to a halt.

As a long-time extraction shooter player, I can tell you this is not a skill issue. Frequency Modulation Boxes in ARC Raiders are intentionally rare, poorly explained, and locked behind some of the most dangerous areas in the game. This guide breaks down exactly where they spawn, how loot logic works around them, and how to farm them efficiently without throwing away your best gear.

What Are Frequency Modulation Boxes in ARC Raiders

Frequency Modulation Boxes are a rare crafting and progression item required for later phases of the Expedition Project. Most players encounter the requirement during Expedition Project Phase 4 or Expedition 2, depending on when they started playing.

Unlike common materials, these boxes are not tied to enemy drops, guaranteed containers, or quest rewards. They only appear as random world loot, but with very strict location rules.

That is why many players go dozens of raids without seeing a single one.

Why Frequency Modulation Boxes Are So Hard to Find

ARC Raiders uses location weighted loot pools. This means certain items can only spawn in specific types of Points of Interest. Frequency Modulation Boxes are restricted almost entirely to Exodus POIs.

If you are looting civilian buildings, generic warehouses, or outdoor containers, you are effectively wasting time if your goal is Frequency Modulation Boxes.

Understanding this is the biggest step toward farming them efficiently.

Best Map for Frequency Modulation Boxes in ARC Raiders

Stella Montis Is the Key

Right now, Stella Montis is the most reliable map for finding Frequency Modulation Boxes in ARC Raiders. It is currently the only map with multiple Exodus POIs, which dramatically increases your chances.

Yes, Stella Montis is dangerous. Yes, it is PvP-heavy. But if you want results, this is where you need to be.

Best Locations on Stella Montis

If you want to maximize your odds, focus on these areas:

Medical Research

Medical Research is one of the highest-tier loot zones on the map. It has a dense concentration of lockers, containers, and rooms that pull from advanced loot tables.

If I had to recommend just one place to check, this would be it.

Assembly

Assembly areas are another strong contender. These zones often spawn industrial containers and lockers that roll rare electronic items.

Loot everything. Even small containers can roll Frequency Modulation Boxes.

Business Center

Business Center is slightly less consistent than Medical Research or Assembly, but it still pulls from Exodus-tier loot pools and is absolutely worth checking.

Metaforge

Metaforge is risky but rewarding. Expect ARC enemies, tight corridors, and high player traffic. If you are confident in your movement and awareness, it can pay off.

All Exodus POIs Matter

The key takeaway is simple.

If the location is marked as an Exodus POI, it can drop Frequency Modulation Boxes. If it is not, your odds drop to nearly zero.

This is why so many players think the item does not exist.

The Naked Run Strategy Explained

Here is the trick veteran players are quietly using.

You can enter Stella Montis with a naked loadout. No weapons, no shield, no augments.

Why does this work?

Because ARC Raiders gives naked players a safe pocket. Any item placed inside that pocket is kept even if you surrender or die.

This allows you to do the following:

Run straight to an Exodus POI
Loot containers until you find a Frequency Modulation Box
Put it in your safe pocket
Surrender and extract

No fighting. No risk. No gear loss.

This method is extremely effective if you are suffering from gear fear or just want to make guaranteed progress.

Risks of Naked Runs

Naked runs are not free wins.

Stella Montis is filled with:

Pops
Fireballs
Ticks
ARC patrols

You need solid map knowledge and good movement to survive long enough to reach loot containers. Expect failed runs. Expect frustration. But compared to losing fully geared kits, this approach saves a lot of resources.

Can Frequency Modulation Boxes Spawn on Other Maps

There have been player reports of Frequency Modulation Boxes appearing on the Spaceport map, specifically near the Rocket Assembly area.

However, these spawns appear to be extremely rare. After many hours of testing, Stella Montis remains the most consistent and reliable option.

If you are short on time, do not gamble on Spaceport.

Can You Craft or Buy Frequency Modulation Boxes

As of now, no.

You cannot craft Frequency Modulation Boxes.
You cannot buy them from vendors.
They are not quest rewards.

The only way to obtain them is by finding them during a raid.

This may change in future updates, but for now, looting is the only path.

Should You Recycle Frequency Modulation Boxes

In earlier builds, players recycled these boxes for advanced components.

Do not do that anymore.

Frequency Modulation Boxes are now tied directly to Expedition progression. Recycling them can permanently block your ability to complete certain project stages unless you find replacements.

Always commit them to your Expedition Project when required.

PvP Considerations While Farming

Stella Montis attracts experienced players for a reason.

If you are going in geared, expect fights. Exodus POIs are high-value targets and players will camp them.

If you are farming solo and want consistency, naked runs or low-risk kits are often the smarter play.

Recommended Loadouts for Safe Farming

If you do not want to go fully naked, bring:

Light armor for movement
A cheap weapon you are willing to lose
Minimal augments

Your goal is not kills. Your goal is loot extraction or surrender efficiency.

Progression Tips from a Veteran Raider

Do not tunnel vision on one POI if it is heavily contested
Learn Stella Montis layouts before farming seriously
Listen for ARC enemy audio cues
Never fight Ticks unless you must

Efficiency matters more than hero plays when farming Frequency Modulation Boxes.

Are Frequency Modulation Boxes Worth the Effort

Yes. Absolutely.

They gate some of the most important Expedition Project upgrades and long-term progression systems. Once you commit them, your account power jumps noticeably.

This is one of those items that separates early-game raiders from players who are ready for long-term progression.

Final Thoughts on Frequency Modulation Boxes in ARC Raiders

Finding Frequency Modulation Boxes in ARC Raiders is not about luck alone. It is about understanding loot pools, choosing the right map, and playing smart instead of greedy.

Stella Montis. Exodus POIs. Medical Research and Assembly. Safe pocket tactics.

Once you lock these ideas in, the grind becomes manageable instead of miserable.

Whether you are farming naturally, running naked for efficiency, or rounding out your inventory of ARC Raiders items through careful planning or external markets like G4mmo, the key is consistency.

Stay patient. Stay mobile. And remember, extraction shooters reward the players who know when not to fight just as much as those who do.
