Owning a radio is only half the picture. Knowing where to listen, when to check in, and which service you’re actually allowed to use is what turns a radio into a real emergency communications tool.

What a “net” is

A net is a scheduled, organized radio session where a control station checks in participants one at a time, usually to pass traffic, practice procedures, or coordinate during an actual event. Local ARES and RACES groups typically run weekly practice nets on a published frequency — a good way to learn the etiquette before it matters.

NOAA Weather Radio

NOAA Weather Radio broadcasts continuous weather and emergency information on seven dedicated frequencies in the 162 MHz band, receivable on inexpensive weather radios that don’t require any license to own or listen to. It’s not a two-way service, but it’s one of the most reliable sources of official alerts during severe weather.

FRS, GMRS, and ham radio aren’t the same thing

Family Radio Service (FRS) radios are license-free, low-power, and fine for short-range use around a campsite or neighborhood. General Mobile Radio Service (GMRS) offers more power and repeater access but requires a low-cost license (no test) per household. Ham radio requires passing an exam but opens far more frequencies, power levels, and repeater networks. None of these substitute for the others — many serious operators keep more than one.

Finding local frequencies and repeaters

Local repeater directories and club websites are the standard way to find active frequencies in your area. Most metro areas have several ARES/RACES-affiliated repeaters, and club nets are usually open to licensed visitors. Printing or saving frequency lists offline is worth doing before you need them — during a real event is a bad time to be searching the internet for a repeater list.

One rule worth knowing

FCC rules allow any station, licensed or not, to use any means necessary to communicate in a genuine life-threatening emergency when no other means are available. It’s a narrow exception, not a workaround for routine use — but it exists specifically because emergencies don’t wait for paperwork.

Knowing this ahead of time, instead of trying to look it up mid-emergency, is the whole point of building an offline reference library in the first place.
