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. locations, 80+ alert types, an 85 dB siren, and an AM/FM tuner, per Midland's spec sheet. This review is based on Midland's published specifications and owner's manual, not on our own long-term testing. Here's what the radio does, 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.
S.A.M.E. filtering is what keeps a weather radio useful at 3 AM: the radio sounds only for the counties and alert types you program, rather than for every alert on the transmitter, which can cover dozens of counties. Midland's spec sheet also lists Public Alert certification, which is the industry standard for alert-radio features. How well any S.A.M.E. radio performs at your address depends on how strong your nearest NOAA transmitter is, so run the built-in channel scan before you rely on it.
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 2,300+ 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
The fast version, condensed from Midland's owner's manual:
- Find your county's FIPS code at weather.gov/nwr/counties (it's a 6-digit number starting with 0)
- In the menu, choose SINGLE or MULTIPLE as your location (ANY receives every alert on the transmitter and skips county programming)
- Enter the 6-digit S.A.M.E. code digit by digit with the arrow keys, then press ENTER; with MULTIPLE, repeat for each county
- Go to MENU → SET EVENTS → EDIT EVENTS to turn individual alert types on or off
- Go to MENU → ALERT TYPE and pick VOICE, TONE, or DISPLAY, then run ALERT TEST
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?
Midland rates the siren at 85 dB, which is in the range of a standard smoke alarm. That is loud, but whether it wakes you depends on the room: distance, a closed door, a fan or white-noise machine all cut into it. Test it from where you sleep, not from where the radio sits. The voice alert mode conveys more information—you immediately know whether the alert is a tornado warning (action required) or a severe thunderstorm watch (awareness only).
The owner's manual offers three alert types: VOICE sounds an alert for 8 seconds and then plays the weather broadcast, TONE sounds the siren, and DISPLAY scrolls the alert text silently. Use ALERT TEST in the menu to hear the siren before you need it. For heavy sleepers or hard-of-hearing household members, Midland sells a pillow shaker and a strobe light that connect to the radio.
AM/FM Radio Quality
The AM/FM tuner is a convenience feature on a weather radio, not its reason to exist; if broadcast reception is a priority, a dedicated Sangean or Tecsun portable is the better tool. AM matters during hurricane aftermath, because AM signals travel farther at night and a distant news station can fill in when local towers are down.
Midland's spec sheet lists preset radio buttons and an AM/FM or buzzer alarm clock, so the WR400 can double as a bedside clock radio.
WR400 vs WR120: Which Midland Should You Buy?
| Feature | Midland WR400 | Midland WR120B |
|---|---|---|
| Price | $89.00 | $46.49 |
| S.A.M.E. counties | 25 | 25 |
| Event codes | 80+ | 85+ (Midland's figure) |
| AM/FM tuner | Yes | No |
| Alarm | 85 dB siren / voice / LED | 90 dB siren (high/medium/low tone) |
| Display | Larger backlit LCD | Smaller LCD |
| Dual alarm clock | Yes | Alarm clock |
| Warranty | 1 year | Not listed on Midland's product page |
| 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 money for its AM/FM tuner, dual alarm clock and USB charging port. 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.
- 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. You get genuine 25-location S.A.M.E. programming, 80+ selectable alert types, an 85 dB siren with voice and LED alternatives, and an 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. Both store up to 25 S.A.M.E. counties, per Midland. The WR400 adds an AM/FM broadcast radio, a dual alarm clock and a USB charging port. The WR120 has no AM/FM radio, is cheaper, and Midland rates its siren louder (90 dB vs. 85 dB), which makes it a solid budget pick or second unit.
How loud is the WR400 alarm?
Midland's spec sheet rates the WR400 siren at 85 dB and lists three user-selectable warning modes: siren, voice alert, or a visual LED flasher. Whether that wakes a given sleeper depends on distance, doors, and background noise, so after setup, wait for the weekly NWS test (or run ALERT TEST from the menu) and check it from your bed. Heavy sleepers and people who are hard of hearing can add Midland's pillow shaker or strobe accessories.
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. Midland's spec sheet and owner's manual call for 4 AA batteries (not included) as emergency backup power. Runtime on AAs depends on battery type and how often alerts fire, so keep spares. 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 an AM/FM broadcast tuner with preset buttons, plus a clock with dual alarms (AM/FM or buzzer), per Midland's spec sheet. 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.
