People often arrive at amateur radio after outgrowing another two-way service. Here is what separates them.
The other services
| Service | License | Power | Typical range | Can you modify or build gear? |
|---|---|---|---|---|
| CB (11 m) | None | 4 W AM / 12 W SSB | A few miles, occasionally worldwide on skip | No — type-accepted radios only |
| FRS | None | 2 W | Under a mile in most terrain | No — fixed antennas, sealed radios |
| MURS | None | 2 W | 1–3 miles | No, but external antennas allowed |
| GMRS | Yes — $35, no exam, covers a family | 50 W | 5–25 miles with a repeater | No — type-accepted radios only |
| Amateur | Yes — exam required | Up to 1,500 W | Local to worldwide | Yes |

When the other services are the right answer
GMRS is genuinely good for family and convoy use: no exam, one license covers your household, and the repeaters are simple. FRS is fine for a ski trip. Neither is a substitute for amateur radio if you want to experiment, reach beyond your county, or operate in an emergency network — and you cannot legally use amateur gear on those services, or transmit on amateur frequencies without an amateur license.
If you already have a GMRS radio, the technician exam is a weekend of study away. See studying.
