Smell Smoke? How to Find Out What’s Burning Near You
“Smoke investigation” is one of the most common calls in the fire service — so common that the fastest way to find out what’s burning near you is usually to listen to the crews being sent to investigate the same smell you’re standing in. Here’s the lookup order, from your own house (rule that out first) to a wildfire three states away.
Key takeaways Inside smell / burning plastic: check your own home; persistent unexplained smell = 911. Neighborhood smell: county fire dispatch on a scanner feed or your own scanner — “smoke investigation” calls answer it live. Regional campfire smell / haze: fire.airnow.gov (smoke + AQI), Watch Duty (western US), state forestry burn schedules. Column of smoke growing: call 911 — early reports matter.
First: rule out your own house
A smoke smell indoors with no obvious source gets treated as an emergency until proven otherwise: check each room, sniff at outlets and appliances (burning plastic or hot electrical smell = breaker off, 911 on). Fire crews run these calls constantly with thermal cameras precisely because smoldering wiring hides in walls. Never talk yourself out of that call.
Local: the “smoke investigation” channel
When the smell or haze is outdoors and local, your fire department is probably already rolling on it — someone else called too. On your county’s fire dispatch you’ll hear:
- “Smoke investigation” / “odor of smoke” calls with the block they’re sent to — often your own.
- The finding: an illegal burn, a barbecue, a vehicle fire, a mulch fire, a neighbor’s fireplace, or a working fire getting a full assignment.
- Fire traffic stays listenable: fire/EMS channels usually remain unencrypted even where police encrypt, making this the most reliably open corner of public-safety radio.
A Broadcastify feed carries it if one exists for your county; the fire & EMS scanner guide and the kit below make it permanent. Seeing trucks but no smoke? That’s its own explainer: fire trucks, but no fire.
Regional: wildfire and prescribed-burn smoke
A campfire smell across the whole area with hazy sun usually isn’t local at all:
- fire.airnow.gov — the definitive map: active fires, modeled smoke plumes, and your real-time air quality (AQI).
- Watch Duty — the best wildfire app for the western US: fires, evacuation zones, and updates from actual fire-radio listeners.
- InciWeb + state forestry pages — official large-incident details and prescribed-burn schedules, the most common “mystery smoke” answer in spring and fall.
- Winter note: still, cold nights trap neighborhood wood smoke under an inversion — everyone smells “fire” because fifty fireplaces are lit.
Smoke-day survival: protecting your indoor air
When the answer turns out to be “a wildfire two states over, for the next week,” the useful work is indoors:
- Close up the house and run the HVAC on recirculate (fan ON, fresh air intake closed) with the best filter it takes — MERV 13 if the system allows.
- The $40 trick: a box fan with a MERV-13 furnace filter strapped to the intake side scrubs a closed room surprisingly well; a true HEPA purifier in the bedroom is better.
- Pick one clean room (bedroom, ideally) rather than fighting for the whole house; keep doors closed and activity low.
- Outdoors, an N95 actually fits the problem — cloth and surgical masks don’t stop PM2.5.
- Judge by AQI, not smell: below ~100, sensitive groups take it easy; above 150, everyone limits exertion; above 200, stay in. Your nose acclimates within minutes and stops being a sensor.
When to stop looking things up and call 911
A visible, growing smoke column, flames anywhere, or that indoor electrical smell — call. Early smoke reports are how small fires stay small, and dispatchers universally prefer a false alarm to a late one. Everything else on this page is for the 95% of smoke smells that have a boring explanation — and for hearing the fire service confirm it, live, while your neighbors are still typing “does anyone else smell smoke??” into Nextdoor.
The fix for next time: a scanner that never sleeps, for about $250
Every lookup method on this page depends on someone else — a feed volunteer, an app's coverage map, an agency webmaster. This kit removes the middleman: a silent little box on a shelf that decodes your county's digital dispatch directly off the air, streams it to any browser in the house, and records every call with timestamps. Next time the sirens go past, the answer is already on your phone — and free, open-source GopherTrunk is the software, so the parts below are the entire cost.
Why two receivers: one dongle stays locked to your police trunked system while the second covers fire/EMS or a neighboring system at the same time — the two channels a "what's going on?" moment actually needs. That's a trick a $500 handheld scanner can't do, and GopherTrunk drives both dongles from one Orange Pi.
Orange Pi 5
around $90
The RK3588 host that runs it all 24/7 — silent, low-power, and strong enough for both dongles with headroom to spare. GopherTrunk ships a native ARM64 Linux build for it.
Orange Pi 5 on Amazon →RTL-SDR Blog V4 kit
around $55
The dongle and the telescopic dipole antenna kit with coax and mounts in one box — this one holds your police system's control channel.
V4 + antenna kit on Amazon →RTL-SDR Blog V4 (second dongle)
around $35
Covers fire/EMS, a second trunked system, airband, or NOAA weather — simultaneously, not by giving up the first channel.

|---|---|---|---|
| Orange Pi 5 | Always-on host for both dongles | ~$90 | Amazon → |
| RTL-SDR Blog V4 + dipole antenna kit | Receiver #1, antennas, coax, mounts | ~$55 | Amazon → |
| RTL-SDR Blog V4 (second) | Receiver #2 — fire/EMS or a second system | ~$35 | Amazon → |
| Powered USB 3.0 hub | Clean, stable power for two warm dongles | ~$35 | Amazon → |
| 16-piece SMA adapter kit | Joins any antenna to any dongle, first try | ~$18 | Amazon → |
| RG316 SMA pigtail kit | Flexible jumpers between hub, dongles, antennas | ~$15 | Amazon → |
| USB-C power supply (5V/4A+) | The Orange Pi 5 needs solid power for 24/7 duty | ~$15 | Amazon → |
| microSD card (64GB, A2) | OS plus months of recorded calls | ~$12 | Amazon → |
Kit total: about $250–275. Worthwhile upgrade once it's earned a permanent shelf: an outdoor discone antenna (~$40) that hears everything from 25–3000 MHz — see the antenna guide. Prefer a Raspberry Pi 5 host instead? Same build, swap the board — Pi 5 (8GB) on Amazon and the SBC build guide.
From boxes to first decoded call
- Flash 64-bit Linux (Debian/Ubuntu image) to the microSD and boot the Orange Pi headless.
- Plug in the powered hub, both dongles, and the antennas — the adapter kit bridges any connector mismatch.
- Install GopherTrunk — one free static binary, no dependencies: download, then follow the setup guide to point it at your county's system from RadioReference.
- Open the web console from any phone or laptop in the house — live calls, talkgroup names, and a scrollable, replayable recording archive.
Two honest caveats before you spend a dime: check RadioReference that your agencies are not encrypted — no device decodes AES — and skim the legality rules for your state (listening is legal in the US; a few states restrict use in vehicles). Rather have a no-computer, pocketable option instead? That's the dedicated scanner guide.
Frequently asked questions
How do I find out what's burning near me right now?
Check, fastest first: your county’s fire dispatch on a live scanner feed — every working fire, brush fire, and ‘smoke investigation’ call is dispatched with a location; Watch Duty (western US) or your state’s wildfire map for wildland fires; PulsePoint where your fire agency participates; and the fire department’s social feed for anything major. A ‘smoke investigation’ call at your block often literally answers your question in real time.
I smell smoke in my house but see no fire — what should I do?
First rule out your own home: check every room, electrical outlets, and appliances — a persistent burning-plastic or electrical smell in one spot is a 911 call, and firefighters investigate exactly this all day. If your house checks out and the smell is general/outdoor (campfire-like), it’s likely drifting smoke from a distant fire — verify on an air-quality or wildfire map.
Why does the whole neighborhood smell like campfire?
Drifting smoke — commonly from a wildfire or prescribed burn tens or even hundreds of miles away, carried on upper-level winds, or from local wood-burning on still winter nights when an inversion traps smoke near the ground. Check fire.airnow.gov: it maps both the smoke plumes and the fires producing them.
What is a prescribed burn and how do I know if the smoke is from one?
A prescribed (controlled) burn is an intentional, permitted fire for land management — a routine source of regional smoke. State forestry agencies post daily burn schedules and locations, and dispatchers frequently field ‘smoke visible’ calls that are logged as known prescribed burns; a scanner catches those confirmations directly.
Is the smoke outside dangerous to breathe?
Judge by the air-quality index, not the smell: fire.airnow.gov and any AQI app show your real-time PM2.5 level and what precautions it warrants. Visible haze with AQI over 150 is unhealthy for everyone — limit outdoor exertion, close windows, run filtration. Smell alone is a poor gauge in both directions.
Who do I call to report smoke?
If you see flames, a growing smoke column, or smell burning inside a building: 911, immediately — early wildfire and structure-fire reports save enormous damage. For a faint distant haze that’s clearly regional drift, check the maps first; if in doubt, call. Fire departments consistently say they’d rather roll on smoke that turns out to be a barbecue.
