Midland WR400 Review: The Bedside Weather Radio We Recommend First
If you can only buy one weather radio, buy the Midland WR400. It is the desktop unit that sits on your nightstand and wakes you up at 3 AM when a tornado warning lands on your county's FIPS code. Up to 25 S.A.M.E. codes, 80+ event codes, an 85 dB alarm, and a real AM/FM tuner—all for under $70. Here's how it performs, where it falls short, and how it compares to the cheaper WR120.
What the WR400 Is Good At
The WR400's job is to sit on your nightstand, connected to AC power, scanning NOAA channel 1–7 for S.A.M.E. codes that match your county, and making enough noise to wake you when one lands. It does that job better than any other weather radio under $100.
In a full year of use, the WR400 fired correctly on every tornado watch, severe thunderstorm warning, flash flood warning, and winter storm warning issued for our FIPS code. Zero false alarms. The alarm tone is piercing—the kind of sound you cannot sleep through even if you try. That's the point.
Weather radio is the public-safety counterexample
Every S.A.M.E. alert that fires on the WR400 is broadcast in the clear on dedicated, unencrypted NOAA frequencies (162.400–162.550 MHz). Anyone with a $30 radio can hear them. That is the design philosophy police radio used to follow—and the design philosophy more than 3,600 agencies have abandoned by encrypting their communications. The WR400 is a working example of what public safety radio looks like when it is built to inform the public, not restrict them.

Setup: Programming Your First FIPS Code
Programming the WR400 is easier than the WR120. The menu walks you through each step in plain language. The fast version:
- Find your county's FIPS code at weather.gov/nwr/counties (it's a 6-digit number starting with 0)
- Find your strongest NOAA channel using the built-in channel scan (press WEATHER, then MENU → "Weather Scan")
- Press MENU → "SAME" → enter the 6-digit FIPS code → save
- Go to MENU → "Event Codes" → disable any alert types you don't want (many people disable routine weekly tests)
- Set your alert mode: voice, siren, or visual-only
Our full S.A.M.E. county code setup guide covers multi-county households, FIPS lookups for split cities, and recommended event codes by region.
Alarm Performance: Can It Actually Wake You?
Yes. We tested the WR400 alarm from a sleeping position 12 feet away with a closed bedroom door and a running ceiling fan. The 85 dB siren woke both adults in the household every time. The voice alert mode is slightly less startling but conveys more information—you immediately know whether the alert is a tornado warning (action required) or a severe thunderstorm watch (awareness only).
A practical tip: enable both siren and voice. The siren wakes you; the voice tells you what to do. You can customize alarm duration from 30 seconds to 8 minutes in the menu.
AM/FM Radio Quality
The WR400's broadcast radio is better than most weather radios in its price range but not as clean as a dedicated Sangean or Tecsun portable. FM reception is solid in urban and suburban areas; AM reception benefits from the built-in ferrite bar antenna and is usable for distant stations at night, which matters during hurricane aftermath when local towers may be down and you need to pull in a distant AM news station.
There are 10 AM and 10 FM presets—enough for weather, two or three news stations, and a couple of local music backups. The speaker is clearer than the WR120's and loud enough to fill a kitchen.
WR400 vs WR120: Which Midland Should You Buy?
| Feature | Midland WR400 | Midland WR120B |
|---|---|---|
| Price | $99.99 | $30–$40 |
| S.A.M.E. counties | 25 | 23 |
| Event codes | 80+ | 60+ |
| AM/FM tuner | Yes | No |
| Alarm | 85 dB siren / voice / LED | Siren / voice / LED |
| Display | Larger backlit LCD | Smaller LCD |
| Dual alarm clock | Yes | Single alarm |
| Warranty | 3 years | 1 year |
| Best for | Primary household weather radio | Second unit or budget setup |
Our take: For your primary bedside weather radio, the WR400 is worth the extra $30. Better warranty, better speaker, AM/FM tuner, and more alert customization. The WR120 remains an excellent choice for a second unit in a basement safe room or a rental property.
Check WR120 price on Amazon if you want the budget option.
Where the WR400 Falls Short
- Not portable. Desktop unit, requires AC. For grid-down, pair with the Midland ER310.
- No USB output. You cannot charge a phone off the WR400.
- Plastic case. Fine for indoors; not rugged.
- AA backup drains fast in alert storms. Expect to swap batteries after a major severe weather event. Lithium AAs last longer than alkaline.
- AC adapter is proprietary. Loss of the adapter means running on AAs until replacement arrives.
Building a Full Kit Around the WR400
The WR400 is step one. A complete home severe-weather kit layers it with:
- Portable backup: Midland ER310 for when the power fails
- Power backup: Jackery 300 or Anker PowerCore 26800—see our weather radio power backup kit
- Regional specifics: Tornado alley guide or hurricane coast guide
- Scanner layer: For unencrypted fire/EMS monitoring, see our beginner scanner guide
Final Verdict
The Midland WR400 is the weather radio we recommend first, full stop. For under $70, you get a three-year warranty, genuine 25-county S.A.M.E. programming, an alarm loud enough to wake you from deep sleep, and a usable AM/FM tuner for post-disaster news. Nothing in its price range competes on feature count.
Buy it if: you want one reliable desktop weather radio for your home.
Skip it if: you only need portable/grid-down operation—get the ER310 instead, or the Sangean CL-100 for premium audio.
Frequently Asked Questions
Is the Midland WR400 better than the WR120?
Yes, for most homes. The WR400 supports up to 25 county codes (vs. 23 on the WR120), has AM/FM broadcast radio, a significantly better speaker, a larger and clearer display, and more alert customization options. The WR120 remains a solid budget pick if you only need tornado and severe thunderstorm alerts with no radio functionality.
How loud is the WR400 alarm?
The WR400 alarm is rated at 85 dB at one meter. In practice, it is loud enough to wake a sound sleeper from across a normal-sized bedroom, even through a closed door. You can also set the radio to flash its LED or speak the full alert voice message instead of, or in addition to, the siren tone.
Can the WR400 monitor multiple counties?
Yes. You can program up to 25 S.A.M.E. county codes, which matters if you live near a county line, commute across counties, or want to know when severe weather is approaching from neighboring areas. See our SAME county code setup guide for step-by-step programming.
Does the WR400 work during a power outage?
Yes, on battery backup. The WR400 accepts 3 AA batteries as a backup. Alkaline AAs will typically give you 24–48 hours of standby monitoring depending on alert frequency. For longer outages, pair it with a portable power station—see our weather radio power backup kit for a full setup.
What alert types can I customize on the WR400?
The WR400 supports more than 80 S.A.M.E. event codes, including tornado warnings (TOR), severe thunderstorm warnings (SVR), flash flood warnings (FFW), hurricane warnings (HUW), winter storm warnings (WSW), AMBER alerts, and civil emergency messages. You can enable or disable any event code individually.
Can I use the WR400 as a regular radio?
Yes. The WR400 includes a full AM/FM broadcast tuner with 10 AM and 10 FM presets, plus clock and dual-alarm functionality. It works as a bedside alarm clock radio that also happens to be your severe weather alert system.
WR400 vs ER310: which should I buy?
Buy both, if budget allows. The WR400 is a desktop AC-powered unit that excels on your nightstand or kitchen counter. The ER310 is a portable crank/solar radio for your go-bag. They solve different problems—the WR400 wakes you up; the ER310 keeps working after the grid fails.
