Frequency Modulation Box
Weight: 1.5 kg | Stack Size: 3 | Sell Value: 3,000 Raider Coins | Found in: Exodus Areas
This guide covers the best maps, container types, and specific locations to farm Frequency Modulation Boxes efficiently. With the right strategy and persistence, you can gather all five boxes in just a few focused farming runs.
Where Are Frequency Modulation Boxes Found
Frequency Modulation Boxes spawn primarily in Stella Montis; they can spawn across the whole map, but have the highest chance in the Northwest of Stella Montis, amongst the Assembly rooms, or inside Yellow Tool Cabinets. Other Locations include the Medical Cabinets or the Breachable Server Lockers, roughly in the centre of Stella Montis.
Though I’ve personally had better luck in the Medical Sector of Stella Montis, inside a Filing Cabinet.
Some even report having some luck in another map, Spaceport – though the stats do not support this; this could be due to lower reports of finding Frequency Modulators in the map as a whole.
Frequency Modulation Boxes are definitely items where you will notice a difference in spawn rates during Night Raids. These raids increase the difficulty and usually reduce visibility. However, in Stella Montis, since we are indoors, visibility is not compromised. Instead, more ARC enemies appear, and players tend to be more aggressive.
These zones contain high-tier technological equipment and advanced components, where Frequency Modulation Boxes naturally appear alongside other valuable Exodus items, such as Ion Sputters and Magnetic Accelerators.
According to community loot data, 80% of all Frequency Modulation Box spawns come from Containers, while the remaining 20% comes from Lockers. When farming Exodus areas on Stella Montis, prioritize searching standard containers, cabinets, and the distinctive blue and white thin drawers that players report having the best luck with.
Best Frequency Modulation Box Locations
Stella Montis accounts for 100% of all Frequency Modulation Box finds according to community voting data, making it the only viable farming map. While some players report finding boxes on The Spaceport at Rocket Assembly, the current data shows Stella Montis as the dominant and most reliable source for this item.
While Frequency Modulation Boxes can technically spawn in any Exodus-tagged container on Stella Montis, certain locations stand out for reliable farming. Below are the best spots organized by building, starting with the most efficient options based on player reports and community testing.
Assembly Workshops
Assembly Workshops is consistently recommended as the single best location for farming Frequency Modulation Boxes. This multi-story building contains numerous searchable containers across both floors, with the upstairs area offering particularly dense loot spawns. Players report finding boxes in the blue and white thin drawers scattered throughout the workshops.
The building features cabinets, standard containers, and drawer units on every level. Search thoroughly from top to bottom, checking every searchable object. Even if the area appears looted, players often miss containers, so always do a complete sweep. Assembly Workshops also spawns Ion Sputters and Magnetic Accelerators, making it efficient for gathering multiple expedition materials in one run.
Assembly Workshops houses a Raider Hatch. Keep one in your Safe Pocket so you can extract immediately after finding your Frequency Modulation Boxes without risking the dangerous journey to a standard extraction point.
Assembly Area
Assembly is the broader industrial zone surrounding the workshops, featuring additional Exodus-tagged buildings and container spawns. The area contains electrical and industrial equipment storage with multiple container types that can drop Frequency Modulation Boxes. This location sees heavy PvP traffic due to its high-tier loot density.
When farming Assembly, work systematically through each building. The thin drawer units found in office-style rooms have elevated spawn rates for rare Exodus items. Coordinate with your squad to cover more ground quickly, as competition for these containers can be intense during peak hours.
Business Center
Business Center offers a less chaotic alternative to the Assembly area while still providing Exodus loot spawns. This location sees lower player traffic compared to Assembly Workshops, making it suitable for solo farmers or players trying to avoid PvP encounters. The building contains office furniture with searchable drawers and cabinets.
The trade-off for reduced competition is a slightly lower container density. However, if you spawn near Business Center at the beginning of a raid, it can be more efficient than fighting through crowds at Assembly. Search all floors methodically and check every drawer unit for potential Frequency Modulation Box spawns.
Lobby
Lobby contains a notable Frequency Modulation Box spawn point on the third floor. Specifically, the closet area next to the security bridge has been confirmed by players as a reliable spawn location. The staircase leading up through the lobby building provides access to multiple container spawns across all levels.
Timing is critical for the Lobby. You need to spawn at the beginning of the round and reach this location before other players. The third-floor closet is a high-priority target, so expect competition if you do not arrive early. Check all searchable containers on your way up the staircase to maximize your chances.
Medical Research
Medical Research is another confirmed Frequency Modulation Box location on Stella Montis. The back corner room of the medical research facility contains containers with elevated spawn rates for rare items. Players report finding multiple boxes in the small locker rooms within this building during single raids.
Focus on the thin drawer units and locker-style containers in Medical Research. One player documented finding two Frequency Modulation Boxes in the same run by thoroughly searching the locker rooms in the back section. The building also provides good cover and multiple exit routes if you encounter hostile players.
A community member reported finding 2 Frequency Modulation Boxes in the middle right room of Medical. Another found 3 in one room on the 2nd floor of Assembly Workshops during a Stella Montis night raid.
Loading Bay
Loading Bay rounds out the Exodus-tagged locations on Stella Montis where Frequency Modulation Boxes can spawn. This industrial area features cargo containers and storage units with searchable loot. While not as frequently recommended as Assembly Workshops, it provides additional farming opportunities if your primary locations are contested.
The Loading Bay works well as a secondary target during your farming route. Hit it after clearing Assembly or Medical Research to maximize your container searches per raid. The area typically sees less traffic than the central Exodus zones, giving you more time to search thoroughly.
Rocket Assembly (The Spaceport)
While community data currently shows 0% of finds on The Spaceport, multiple players mention Rocket Assembly as an alternative Exodus location. This building sits in the upper-right middle section of the Spaceport map and contains Exodus-tagged containers. If Stella Montis proves too competitive, The Spaceport offers a backup option.
The Spaceport generally sees lower player populations than Stella Montis, which can make farming less stressful even if spawn rates are lower. Consider rotating to Rocket Assembly if you are struggling with PvP encounters on Stella Montis or want a change of pace from the standard farming route. Many players are generally sick of Stella Montis, as this is the only location where many items can spawn, mixed with the high-aggression nature of the map.
What Is A Frequency Modulation Box
Frequency Modulation Boxes are classified as Rare recyclable items in Arc Raiders, identified by the blue rarity tag. Each Frequency Modulation Box weighs 1.5 kg, stacks up to 3, and sells for 3,000 Raider Coins at vendors. The item description notes it can be recycled into crafting materials.
When recycled at the Raider Den, a Frequency Modulation Box yields 1 Advanced Electrical Component (worth 1,750 coins) and 1 Speaker Component (worth 500 coins) for a total recycle value of 2,250 coins. Salvaging topside produces only 2 Electrical Components, making proper recycling at the Den significantly more valuable if you need materials.
Why You Need Frequency Modulation Boxes
Frequency Modulation Boxes serve a critical purpose in Arc Raiders progression, making them worth farming rather than selling immediately. Understanding the expedition requirements helps you prioritize this item appropriately.
Expedition 2: Outfitting Project
The primary use of Frequency Modulation Boxes is the Outfitting project, which is Phase 4 of 5 in Expedition 2. You need exactly 5 Frequency Modulation Boxes to complete this project and advance to the expedition’s final stage. This requirement makes them one of the final items you will need to gather before completing Expedition 2.
Given their Rare status and exclusive spawn locations on Stella Montis, Frequency Modulation Boxes should be prioritized for project completion. Only sell or recycle extras once you have gathered the 5 required for the Outfitting project. Farming these boxes early, before other players rush to complete Expedition 2, gives you a significant advantage, though typically some players will also be at the same stage.
Recycle vs Sell
Frequency Modulation Boxes sell for 3,000 Raider Coins each. Recycling yields 2,250 coins worth of materials (1 Advanced Electrical Component + 1 Speaker Component). Selling gives you 750 more coins directly, making it the better option for pure profit.
However, if you specifically need Advanced Electrical Components for crafting, recycling becomes worthwhile since these materials are essential for various upgrades. The recommendation is to sell Frequency Modulation Boxes once you have completed the Outfitting project, unless you actively need the recycled materials for other crafting recipes.
Tips For Farming Frequency Modulation Boxes
Frequency Modulation Boxes stack to 3, and each weighs 1.5 kg. Plan your inventory space accordingly. A dedicated farming run can net 1 to 3 Frequency Modulation Boxes if you hit the right Exodus areas and get favorable spawns, though RNG plays a significant role in your success.
Always use your Safe Pocket for Frequency Modulation Boxes as soon as you find them. Equip any Augment in a custom Build rather than running free loadouts to ensure you have Safe Pocket access. Losing a rare Exodus item to a PvP death is devastating when you need exactly 5 for the expedition project.
Consider manipulating the aggression-based matchmaking system to get friendlier lobbies. Spend 3 to 4 games prior to your serious loot runs, avoiding combat and not shooting other players. You can do this with free kits to minimize risk. After several peaceful games, the matchmaking should place you in less hostile lobbies where farming becomes significantly easier.
Turn on Fill Squad when farming Stella Montis. Squad games have fewer total groups competing for the same loot compared to solos, where every player is an individual competitor. With squads, the player population is distributed across fewer teams, reducing the concentration of players hitting prime farming spots at the same time.
Do not skip already-looted areas. Players frequently miss containers, especially the thin drawer units that spawn Frequency Modulation Boxes. Always do a complete search of Assembly Workshops even if containers appear opened.
Run multiple short raids rather than one long expedition. Hit Assembly Workshops or Medical Research on Stella Montis, grab your Frequency Modulation Boxes, and extract quickly using a Raider Hatch from your Safe Pocket. The spawns refresh each raid, making quick targeted runs more efficient than full map exploration.
Expect 3 to 6 runs to gather the 5 Frequency Modulation Boxes needed for Expedition 2. The item has a low drop rate compared to other materials, so persistence is essential. With consistent farming at Assembly Workshops and Medical Research, you should complete the project requirement within a dedicated farming session. Personally, I’ve found 2 in 1 run, then had none for 5+ Runs, RNG may not be in your favor.
