The 151 MHz channels can only be operated in narrow band mode. This is against the FCC regulations but is widespread in certain areas due to the availability of open-band VHF/UHF radios, easily modified ham radio equipment that can transmit on the MURS frequencies and the adoption of the MURS frequencies by militia and prepper groups. There are reports of cross-band repeaters using the FRS frequencies and MURS, in addition to high powered MURS simplex repeaters located on mountaintops or tall buildings in urban areas. CB signals bend over hills and around obstacles much better than MURS (at 150 MHz) or FRS/GMRS (at 460 MHz) signals. To avoid confusion, check your radio against a known Motorola However, FCC rules permit higher power for telemetry, data links and telecommand purposes on the six 27 MHz R/C frequencies. Retevis RT-27V MURS VHF In more congested areas, stores are more likely to use non-standard CTCSS or DCS tones to avoid interference. It is much easier to set up high gain antennas on VHF vs. 11 meters/CB frequencies. Motorola radios tend to have 154.57 and 154.6 hard-programmed for wideband FM mode (25 kHz channel or 20 kHz bandwidth). By the way, you may hear CTCSS tones sometimes called PL tones. Skills we advocate to get you through anything life throws at you. Enter the repeater output frequency, 443 . Information on news, history and events both inside ITS and throughout the world. Tips on staying active, fueled and ready to overcome all obstacles. Militia groups are encouraged to set up simplex repeaters on the MURS and FRS frequencies, ideally more than one (one for general use and another for "private" or "discrete" use). 154.570 MHz FM is the MURS Survivalist channel, known as MURS Channel 4 or the Blue Dot Channel. What’s not to love about MURS? MURS, or the Multi-Use Radio Service band is part of the PRS, or Personal Radio Service bands, as outlined by 47 CFR Part 95J of the FCC (Federal Communications Commission), which regulates and makes rules for the use of all RF (Radio Frequency) radio spectrum in the United States. Maximum transmitter output power is 2 watts. MURS, American VHF CB, also rendered as "Multi-Use Radio Service" - not to be confused with similar services such as FRS/GMRS, regular old 26-27 MHz CB, VHF marine or licensed land mobile (business radio) services. The BTECH MURS-V1 2-way Radio is one of the best MURS two-way radios that you can use for retail, manufacturing, business, and personal applications. In the United States, the Multi-Use Radio Service (MURS) is a licensed by rule two-way radio service similar to Citizens Band (CB). At MURS frequencies, signals bend over hills better, but GMRS signals are better at bouncing off of surfaces and penetrating into/escaping out of buildings. Some Midland radios, like the T70 series, only have 83 DCS privacy codes. Murs & Co is an extension of my brand as an influencer @mursalison. Because the FCC rules allow for any mode on the MURS frequencies (as long as the bandwidth restrictions are followed), MURS is becoming more and more popular for unlicensed fixed or point-to-point data link and telemetry systems. 6104 W Pioneer Pkwy Ste 212Arlington, TX 76013, Proudly managed inthe great state of Texas. : Indicates that no method is used for this, either transmit or receive. Review Motorola RMM2050 [tabs] About [callout] Rule Part 47 C.F.R, Part 95 [/callout] The Multi-Use Radio Service (MURS) uses channels in the 151 – 154 MHz spectrum range. Another hidden benefit of MURS frequencies are the PL codes (Private Line codes) or CTCSS (Continuous Tone Coded Squelch System) which are sub-audible tones that allow users to operate on the same channel without hearing chatter directed to other users. PRSG has a wonderful FAQ section where you can obtain more information pertaining to MURS. (3) GMRS repeater input only. Enhanced audio quality: Powerful 1500 mW speaker ensures clear communication without distracting feedback in … Best practices involving up to date medical information and life saving equipment. Emergency preparedness recommendations include monitoring channel 3 (CB, FRS and MURS) for 3 minutes at :00 (top of the hour), :15, :30 (bottom of the hour) and :45, so 3 minutes every 15 minutes - for emergency calls/communications. License free, low cost, two-way communication. MURS is similar in function and intended use to the Freenet license free 149 MHz service available in Germany, the various Nordic JAKTRADIO 155 MHz license free hunting radio services, the 142 MHz/143 MHz VHF CB band in Indonesia, the VHF LADD VHF trucking channels in Canada, and the "VHF 245" 245 MHz VHF CB service in Thailand, among other similar CB-like services worldwide. ©2009-2021 ITS Tactical // Imminent Threat Solutions. Here are some great comparisons courtesy of PRSG. Antenna height is limited to 20 feet above structure or 60 feet above ground, whichever is the greater. The stipulations for MURS use provided by the FCC restrict any transmitter in excess of two watts, but any type of antenna is allowed as long as the tower height (with antenna) is no greater than 60 feet high. Reported MURS simplex repeater frequencies and tones include: There is an effort (the AmRRON CH3 Project) to standardize the use of "channel 3" as a general "prepper" or emergency preparedness "calling" channel across the three Part 95 services, MURS, CB and FRS (MURS channel 3 - 151.94 MHz, CB channel 3 - 26.985 MHz and FRS channel 3 - 462.6125 MHz) in conjunction with HF/VHF/UHF amateur frequencies. With many types of radio service, there is a unique channel number associated with each and every frequency that can be used. Business Exclusive Frequencies - Operates on 5 MURS FCC license free frequencies and features 219 PL/DPL codes, including 6 customizable codes to help ensure a clear signal. See also: CB repeaters. For suggested and unofficial channel usages see the Family Radio Service and General Mobile Radio Service wiki articles. Multi-Use Radio Service (MURS) is an unlicensed two-way radio service similar to CB but on VHF FM. Another hidden benefit of MURS frequencies are the PL codes (Private Line codes) or CTCSS (Continuous Tone Coded Squelch System) which are sub-audible tones that allow users to operate on the same channel without hearing chatter directed to other users. Equipment you need for wherever your adventures in life take you. Many GMRS radios can communicate through repeater stations for extended range (typically up to twenty miles or more, sometimes. Tools to give you the advantage over any Imminent Threats that come your way. Tones are ‘Squelch Codes’ because they are used to control when the squelch (mute function) of your radio opens up so you can hear it. A3E and A2D emissions (AM voice and AM data) are limited to 8.0 kHz maximum bandwidth on all 5 MURS channels. The ACS-CERT Communications Plan uses the Motorola FRS Channel Numbering Standard. (2) GMRS repeater output. Wal-Mart, Costco, Sam's Club and other retailers that started using 154.600 MHz and 154.570 MHz back when licenses were required have continued to use these frequencies after they were made license-free. Operation is subject to the condition that this device does … If so, we’d love to have you as a Crew Leader by joining our annual membership! CTCSS and DCS (PL and DPL) are user-programmable for each channel. Each of the five frequencies can not only transmit voice, but also data. Transmit code is taken from the DTCS Code column, receive code from the DTCS Rx Code column. This is true of CB and of MURS radios – indeed, with MURS there are both channel numbers (1 … Vehicle-to-vehicle MURS communications will probably be comparable and possibly quite superior to that available in the CB service. Due to the favorable propagation characteristics of the 150 MHz VHF band, telemetry systems using MURS are sometimes used as an alternative to unlicensed 26 MHz/27 MHz telemetry systems. They should make note of any/all activity heard on the channel, with special attention paid towards the CTCSS/DCS (PL/DPL) tone squelch tones or codes in use. MURS communications will not suffer from the kind of long-range “skip” interference frequently encountered on CB radio at 27 MHz. Short range on-site paging and one-way voice driveway sensors are also found on the MURS channels. PL Tone Std. Like Kenwood, CTCSS is referred to as QT and DCS is referred to as DQT. Wal-Mart has a habit of using 154.57 and 154.6 with carrier squelch (CSQ), even in radio congested environments like large shopping malls and urban or suburban areas. This can lead to interference issues when multiple stores are using MURS frequencies in a small area. Store-and-forward packet operation is explicitly prohibited. FRS users may also use channel 1 as the "default" channel or de facto calling channel, while higher power GMRS users officially use 462.675 [141.3 Hz CTCSS/PL]. 7.) This page has been accessed 46,582 times. Someone scanning the MURS frequencies will often hear short data bursts (often just breaking the radio's squelch). (MURS is an important part). CB communications can also be significantly degraded by noise from vehicle ignition systems and from other man-made sources. Short distance voice and data service for use by the general public for personal and business communications. Technically this means they're "grandfathered" users and enjoy primary status on the frequency - although this is murky in the FCC rules. It is an important distinction to understand while organizing people with different brand MURS radios. Some CB and ham radio operators also use the MURS frequencies due to favorable propagation characteristics, often with high power. Depending on the surrounding terrain, MURS units connected to roof-mounted antennas might even outperform full-power (50 watt) GMRS mobile units, although the GMRS units should have a greater range in open terrain. Radios used by Wal-Mart, for example, transmit 20K0F3E emission on 154.57 MHz and 154.6 MHz but transmit 11K0F3E on 151.82 MHz, 151.88 MHz and 151.94 MHz. Reading Frequency Values Reading CTCSS/DPL Values The Frequency value is only one digit as RDM When reading the values for CTCSS/PL Codes Series MURS Two-Way radios have 5 the radio signals the digit codes each time the predefined frequencies. Technology for understanding the digital world and mitigating electronic threats. Sometimes multiple systems can be heard on the same frequency during favorable band conditions and depending on the height of the receiving (and transmitting) antennas. Business-Exclusive Frequencies: Operates on 5 MURS FCC license free frequencies and features 219 PL/DPL codes, including 6 customizable codes to help ensure a clear signal. You may connect a MURS radio to an external or exterior antenna. 7 0 0. The best example of this are the driveway alarms which transmit a signal via MURS when the IR sensor is tripped. See the FRS and GMRS pages for more information. While this is not encryption, anyone not operating with the same PL code won’t hear your conversation. Default Channels Frequencies (programmed in order to talk to the old Wal-Mart VHF XTN series XV2600 or CP100 series radios), Default Channels Frequencies - Wal-Mart MURS Plan (see above as well), Note, there are 2 and 8 channel versions of the TK-2200 series and TK-3200 series radios, Baofeng Baofeng Tech BTECH MURS-V1 VHF MURS FCC Approved Portable Walkie Talkie MURS Radio.
