Multi-Use Radio Service (MURS)
 1. What is the Multi-Use Radio Service?
The MURS is a license-free "citizens band" radio service established by the U.S. FCC. It is intended for short distance communication of a personal or business nature by the general public. Communication can be of voice, data, or image. Effective radiated power can be up to 2 watts.
 2. Who can use a MURS radio? Can they be used anywhere?
Any citizen in the United States, not representing a foreign government, can use a MURS radio.
A MURS radio can be used on a ship, with the permission of the captain. A MURS radio can not be used on a plane in-flight.
 3. What range can I expect?
When using "rubber-duck" type antennae, you can expect a range of up to 3 miles. With well mounted external antennae, you may obtain a range of up to 6 to 10 miles or more depending on terrain.

 5. How is MURS functionally different from the Family Radio Service?
(1) An effective radiated power of up to 2 watts is permitted -- 4 times more than FRS.
(2) Connecting an external antenna, such as a mobile car mounted antenna, to a MURS radio is permitted -- FRS radios must use a non-removable antenna; use of an external antenna is not permitted.
(3) Due to (1) and (2) above, much greater range is possible with MURS than with FRS. A range of up to 6 to 10 miles or more (depending on terrain) can be achieved with MURS radios using external car (roof-mounted) antennas or well placed external base station antennas.
(4) You can use a MURS radio to transmit data, whereas an FRS radio is limited to voice communications.
(5) The use of repeaters and telephone auto-patch is not specifically prohibited (however, this may change).
 6. Where can MURS radios be purchased?
Currently MURS has received much less attention from radio manufacturers than has FRS. As of yet, there are no MURS specific radios available. However, certain business radios currently available from mobile radio retailers, are MURS compatible. To be MURS compatible, a business radio must (1) transmit only on MURS frequencies, (2) have an effective radiated power of no more than 2 watts (including antenna and cable), (3) a maximum deviation <= 2.5kHz, and (4) is currently type-approved for Part 90 operation.
