Weather Alert Radio Comparison
Not every weather radio is created equal. The single most important capability separating a useful weather alert radio from a noisy nuisance is its ability to filter by Specific Area Message Encoding (SAME) code and by individual event type. Without SAME, your radio will alert on every watch and warning anywhere within the transmitter’s coverage area, which often spans a dozen counties or more. Within a few weeks of false alarms for distant storms, most people simply turn the radio off. That defeats the purpose.
This chart compares the weather radios most commonly recommended for preparedness use, focused on the two filtering features that matter most: SAME county filtering and per-event-code selection (for example, the ability to silence flash flood statements while keeping tornado warnings active).

What the columns mean
SAME Filtering
The radio can be programmed with one or more 6-digit county codes. It stays silent unless an alert is broadcast for one of those counties. This is the feature that makes a weather radio actually usable at 3 a.m.
County Codes Stored
How many counties the radio can hold at once. If you live near a county line, work in another county, and have family in a third, you need a radio that holds at least 3-5 codes. Most desktop units handle 23-25.
Event Code Selection
The ability to turn individual event types on or off. For example, suppress flash flood statements during routine rainy seasons while keeping tornado warnings and severe thunderstorm warnings active. Note that some events (Tornado Warning, Severe Thunderstorm Warning, Evacuation Immediate, and a few others) cannot be disabled on most certified radios.
Public Alert Certified
An industry certification (administered by CEA / Consumer Technology Association) confirming the radio decodes SAME, displays event codes, sounds the 1050 Hz tone, and meets minimum performance standards. Worth looking for on the box.
Auto NOAA Receive
The radio monitors a NOAA frequency in the background and unmutes when it hears the 1050 Hz alert tone, but it cannot filter by county or event. You will hear every alert in the transmitter’s coverage area.
Battery Backup
Mandatory. The radio is most needed during the power outage that follows the storm. Desktop units typically use AA cells as backup; portable units have built-in lithium plus crank and solar.
Recommendations by use case
Home base (one radio only)
Midland WR400 or Sangean CL-100. Both are Public Alert certified, both hold 25 SAME counties, both allow event-code selection, both have AM/FM and battery backup. The CL-100 adds an external alert jack for strobes or bed-shakers, which matters in households with hearing-impaired family.
Bedroom / bedside
Midland WR120 or WR120DSP. Smaller footprint, alarm clock built in, color-coded warning/watch/advisory LEDs. The DSP variant adds adjustable siren volume and partial-county alerting.
Go-bag / vehicle
Midland ER310 or Eton Odyssey. No SAME filtering, but rugged, multi-power, and they will receive the alert when it matters. The Odyssey uses a replaceable 18650 cell for long-term sustainability.
Portable with SAME
Eton FRX5 / FRX5BT or Eton Sidekick. These are the rare crank radios that decode SAME. Useful as a hybrid home/travel unit if you only want to buy one radio.
Hearing-impaired household
Sangean CL-100 with an external strobe or bed-shaker connected to its alert jack. No other certified unit in this price class offers that port standard.
Already own a Baofeng or BTECH
You can monitor the NOAA frequencies (162.400 – 162.550 MHz) but the radio cannot decode SAME data bursts and cannot trigger an alert when silent. Treat it as a supplemental listening tool, not a replacement for a dedicated alert radio.
Programming notes
Every SAME-capable radio needs three things to work correctly:
- The correct NOAA frequency for your area. The seven frequencies are 162.400, 162.425, 162.450, 162.475, 162.500, 162.525, and 162.550 MHz. Use the strongest signal you can receive. The NWS station listing tool will tell you which transmitter covers your location.
- One or more 6-digit SAME county codes. Each county and county equivalent in the United States has a unique code. Program at least your home county and any adjacent counties if you live near a border. If you commute, program the work-county code too.
- Your event-code selections. By default most radios alert on every operational event code. Tighten this down once you understand the alert mix in your area. Tornado Warning, Severe Thunderstorm Warning, Flash Flood Warning, and Civil Emergency Message should always stay on. Statements and routine advisories are often candidates for muting.
