S.A.M.E. County Code Setup Guide: Program Your Weather Radio in 10 Minutes
A weather radio is useless until you program it. Out of the box, most S.A.M.E. radios alarm on every single NOAA alert broadcast by your nearest transmitter—watches in counties three hours away, test tones every Wednesday, and nuisance alerts that teach you to ignore the radio entirely. Ten minutes of setup turns that nuisance machine into a device that only makes noise when you actually need to act.
What S.A.M.E. Actually Is
S.A.M.E. stands for Specific Area Message Encoding. It's a digital header the National Weather Service prepends to every alert broadcast over NOAA Weather Radio. The header encodes which counties the alert affects, what type of alert it is, when it was issued, and when it expires. Your receiver reads the header, compares it to your programmed codes, and decides whether to alert.
Without S.A.M.E., a weather radio in Pennsylvania would alarm when NOAA broadcasts a rip-current advisory for the New Jersey shore, because both counties share transmitter coverage. With S.A.M.E. programming, you only hear alerts for the specific codes you entered.
Why NOAA's design matters
S.A.M.E. is a textbook example of public safety broadcasting done right: universally receivable, free, standards-based, always unencrypted on seven dedicated frequencies. It's the design philosophy police radio used to follow. Today, more than 2,300+ agencies have encrypted their communications, so the average household can hear tornado warnings but not the dispatch calls during a local emergency. Weather radios are the last reliable real-time public safety feed in many communities.
Step 1: Look Up Your FIPS Code
The National Weather Service maintains the official S.A.M.E. code list at weather.gov/nwr/counties. Select your state, then find your county. The code you want is the 6-digit number in the "SAME Code" column, which always starts with 0.
Examples:
- Harris County, Texas:
048201 - Cook County, Illinois:
017031 - Miami-Dade County, Florida:
012086 - Oklahoma County, Oklahoma:
040109 - Los Angeles County, California:
006037
Pay attention: FIPS codes are not the same as ZIP codes or area codes. Use the official NWS list, not a third-party lookup.
Multi-county households
If you live near a county line, add your neighboring counties. If you commute, add your work county. If you have a cabin in another state, add that county too. The Midland WR400 supports 25 codes, which is more than most people ever need.
Step 2: Find Your Strongest NOAA Channel
NOAA broadcasts on seven frequencies. Your radio only listens to one at a time. Before programming S.A.M.E. codes, scan to find the strongest transmitter in your area:
| Channel | Frequency |
|---|---|
| WX1 | 162.400 MHz |
| WX2 | 162.425 MHz |
| WX3 | 162.450 MHz |
| WX4 | 162.475 MHz |
| WX5 | 162.500 MHz |
| WX6 | 162.525 MHz |
| WX7 | 162.550 MHz |
On the WR400: press MENU, use the arrows to reach SET CHANNEL, press ENTER, pick a channel, and press ENTER again. On the ER310: press BAND to reach the weather band, then use the TUNE buttons to find the strongest channel. Choose the one with the clearest voice and strongest signal. You can also look up your local transmitter's frequency at weather.gov/nwr.
Step 3a: Programming the Midland WR400
- Press MENU, then use the ▲/▼ arrows until the display shows
SET LOCATION; press ENTER - Choose
SINGLE(one county) orMULTIPLE(up to 25) and press ENTER.ANYreceives every alert on the transmitter and skips county programming - Pick your country, state, and county from the built-in lists (pressing ENTER after each), then choose

MULTIPLE, repeat for slots02onward - Press MENU to save and exit, then run
ALERT TESTfrom the menu to hear the siren
These steps are condensed from Midland's WR400 owner's manual; full details are in our Midland WR400 review.
Step 3b: The Midland ER310 (no S.A.M.E.)
The ER310 has no county-code programming. Midland's owner's manual (Rev B, August 2025) describes a channel-wide weather alert instead:
- Press BAND until you reach the weather band, and use the TUNE buttons to select your strongest NOAA channel
- Press WX ALERT to arm the alert; the
WXicon flashes while it is enabled - When an alert arrives on that channel, the radio sounds a siren and flashes the flashlight and backlight for one minute; press any button to stop it
Because it can't filter by county, the ER310 will sound for alerts anywhere in its transmitter's coverage. Use it as a portable backup and rely on a S.A.M.E. radio at home. Full ER310 specs, drawn from Midland's documentation, are in our Midland ER310 review.
Step 4: Choose Your Event Codes
S.A.M.E. event codes tell your radio which alert types should trigger the alarm. Most radios default to "all events enabled," which is why they seem to alarm constantly. Turn off what you don't need.
Essential event codes (enable everywhere)
- TOR — Tornado Warning
- SVR — Severe Thunderstorm Warning
- FFW — Flash Flood Warning
- CEM — Civil Emergency Message
- EVI — Evacuation Immediate
- EAN — Emergency Action Notification
Tornado alley (add these)
- TOA — Tornado Watch
- SVA — Severe Thunderstorm Watch
- FFA — Flash Flood Watch
See our tornado alley weather radio guide for region-specific recommendations.
Hurricane coast (add these)
- HUW — Hurricane Warning
- HUA — Hurricane Watch
- TRW — Tropical Storm Warning
- TRA — Tropical Storm Watch
- SSW — Storm Surge Warning
- SSA — Storm Surge Watch
See our hurricane coast weather radio guide.
Winter weather (add these in cold climates)
- BZW — Blizzard Warning
- WSW — Winter Storm Warning
- WSA — Winter Storm Watch
Disable these (for most households)
- RWT — Required Weekly Test (optional; your local NWS office sets the day and time)
- DMO — Practice/Demo Warning
- ADR — Administrative Message
Step 5: Test Your Setup
NOAA broadcasts a Required Weekly Test (RWT) once a week, on a day and time set by your local NWS office. If you left RWT enabled, you'll hear it fire. If you disabled it, you can still watch the LED flash and the display change state during the test—proof that your programming is active and the radio is receiving the transmitter.
You can also force a test manually on most radios. On the WR400, press WEATHER once to hear the current broadcast; if you hear the automated voice clearly, your radio is locked onto a strong signal.
Troubleshooting
- If the radio stays silent during known alerts, verify the FIPS code is correct (double-check on weather.gov) and confirm the relevant event code is enabled.
- If it alarms for alerts that don't affect you, you're probably programmed for a neighboring county you don't want — review all 25 slots.
- For a weak or absent signal, try all 7 channels, move the radio closer to a window, extend the antenna fully, and check local transmitter outages at weather.gov/nwr.
- Constant alerts with RWT disabled usually mean ADR (administrative) is still enabled — disable it.
Completing Your Emergency Setup
A programmed weather radio is step one. A complete emergency communication setup adds power backup and, where feasible, a scanner:
- Weather radio + battery + solar bundle for multi-day outages
- Regional guides for tornado alley and the hurricane coast
- Midland ER310 with crank and solar for a portable option
- Emergency weather scanner guide for areas where fire and EMS are still unencrypted
Frequently Asked Questions
What is a S.A.M.E. code on a weather radio?
S.A.M.E. stands for Specific Area Message Encoding. It's a six-digit code that represents a specific county, parish, or marine zone. When the National Weather Service issues an alert, it broadcasts the S.A.M.E. codes for the affected areas. Your weather radio compares incoming codes to the ones you've programmed and only activates the alarm if they match.
How do I find my county's FIPS code?
Visit weather.gov/nwr/counties, select your state, and find your county in the list. Each county has a six-digit code that starts with 0 (e.g., 017031 for Cook County, Illinois). For marine zones, use weather.gov/nwr/marine. Always verify using the official NWS list rather than trusting third-party sources.
How many counties can I program into a weather radio?
It varies by model, so check the spec sheet. Midland lists up to 25 programmable counties for both the WR400 and the WR120. The Midland ER310 is not a S.A.M.E. radio: per its owner's manual it sounds for any alert on the selected NOAA channel, with no county programming.
Should I add neighboring counties to my weather radio?
Yes, if you live within about 20 miles of a county line or if severe weather typically approaches from a specific neighboring county. For tornado alley households, add the two or three counties to your west and southwest. For hurricane zones, add coastal counties to your south and east.
What event codes should I enable?
At minimum, enable Tornado Warning (TOR), Severe Thunderstorm Warning (SVR), Flash Flood Warning (FFW), and Civil Emergency Message (CEM). In hurricane zones, add Hurricane Warning (HUW) and Tropical Storm Warning (TRW). In winter-prone areas, add Blizzard Warning (BZW) and Winter Storm Warning (WSW). Disable the Required Weekly Test (RWT) if the weekly test tone wakes the baby.
Do I need to reprogram after a power outage?
No. S.A.M.E. programming is stored in non-volatile memory on all modern Midland, Sangean, and Eton weather radios. A power loss does not erase your county codes or event settings. Your clock may reset, but your alert programming persists.
Are NOAA weather alerts encrypted?
No, and they never will be. NOAA Weather Radio All Hazards broadcasts on seven dedicated frequencies between 162.400 and 162.550 MHz, always in the clear. This is the opposite of the trend in police radio, where more than 2,300+ U.S. agencies have moved to encrypted systems that block public monitoring.
