Unlicensed VHF Frequencies
Summary The TS4000 radio modem can be used without a license, with some restrictions, in the United States on five specific VHF frequencies under the MURS (Multi-Use Radio System) rules of the FCC. The MURS rules allow voice or data communications for personal or business activities of the general public. [see 95.401(e)] Note that the FCC may change, restrict, modify or amend these rules in the future. Frequencies and Channel Bandwidth MURS allows unlicensed use on the following 5 frequencies and bandwidths: [see 95.632(a),(b)} 151.820MHz, bandwidth: 11.25 KHz 151.880MHz, bandwidth: 11.25 KHz 151.940MHz, bandwidth: 11.25 KHz 154.570MHz, bandwidth: 20.0 KHz 154.600MHz. bandwidth: 20.0 KHz This channel bandwidth (occupied bandwidth) of the TS4000 is configured on the Radio tab of the TS4000 configuration software. Power The MURS frequencies can be used with up to 2 watts or transmit power. [see 95.639(h)] For the TS4000 Radio Modem, the transmit power is set on the Radio tab in the TS4000 configuration software. Antennas The MURS rules do not currently limit the type of antenna. Antenna Height The highest point of any MURS antenna must be no more than 18.3 meters (60 feet) above the ground or 6.10 meters (20 feet) above the highest point of the structure on which it is mounted. [see 95.1315] Channel Sharing The MURS rules specify that the channels must be shared with other users. [see 95.1309] The TS4000 is designed to minimize interference with other users by listening before it transmits. However, the best way to minimize interference with other channel users is to use the TS4000’s Clear Channel Scan feature. Clear Channel Scan automatically and dynamically selects the frequency with the least amount of interference. Clear Channel Scan is set on the Radio tab of the TS4000 Configuration software. The MURS rules do not allow the use of store and forward repeaters. [see 95.1311] Location A MURS radio can be used “within or over any area of the world where radio services are regulated by the FCC”. [95.405(a), 95.1303] A MURS radio may not be used aboard an aircraft in flight. [95.1303(b)] Equipment The TS4000 Radio Modem (Part# TS4000-05C15SBB) meets the requirements for MURS. Note that the TS4000 must be configured correctly to meet the MURS rules. The TS4000 can be ordered with a MURS compatible configuration using part# TS4000-05C15SBB-MURS.
