Multi-Use Radio Service (MURS) is an unlicensed two-way radio service similar to Citizens Band (CB). These radios may have a maximum legal output of 2 watts. The highest point of any MURS antenna must not be more than 18.3 meters (60 feet) above the ground or 6.10 meters (20.0 feet) above the highest point of the structure to which it is mounted, whichever is higher.

  • FCC License: No
  • Max Output: 2 watts
  • Frequency: 2 meter

MURS comprises the following five frequencies:

Channel 	Frequency 	Authorized bandwidth 	Channel Name
1 	151.820 MHz 	11.25 kHz 	N/A
2 	151.880 MHz 	11.25 kHz 	N/A
3 	151.940 MHz 	11.25 kHz 	N/A
4 	154.570 MHz 	20.00 kHz 	Blue Dot
5 	154.600 MHz 	20.00 kHz 	Green Dot

MURS range will vary depending on antenna size and placement. With an external antenna, ranges of 10 miles or more can be expected.

The two channels in the 154Mhz range can be operated in wide band 25khz while the first three are restricted to narrow band 12.5khz only.
