MURS stands for Multi User Radio Service, and is one of the best kept secrets in personal and family radio communications. A3E and A2D emissions (AM voice and AM data) are limited to 8.0 kHz maximum bandwidth on all 5 MURS channels. Handheld radios broadcasting on MURS frequencies can experience a range of two miles to eight miles depending on terrain and obstructions, while MURS Base Stations can reach up to 20 miles. PL Tones (Private Line, a Motorola Trademark) are used to control repeaters, exclude foreign traffic and control remote sites thruout the Public Safety and business two-way world. Some users only appear during specific times of the day/week. Antenna height is limited in FCC rules and the highest point of the MURS antenna must not be 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. 6104 W Pioneer Pkwy Ste 212Arlington, TX 76013[email protected]. 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 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.

Motorola radios tend to have 154.57 and 154.6 hard-programmed for wideband FM mode (25 kHz channel or 20 kHz bandwidth). Notes (1) Shared FRS and GMRS simplex. 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. Even if a channel appears to be quiet with casual listening...that is often not the case. This can lead to interference issues when multiple stores are using MURS frequencies in a small area. MURS-based VHF systems range from simple handheld radios programmed with the MURS and FRS frequencies (for example, the Baofeng UV-5R and UV-82 series) to high powered mobile and base station simplex networks to simplex and duplex repeater networks. With CTCSS and DCS, there are literally hundreds of options and repeater access protection is possible even in urban areas with congested MURS and FRS/GMRS frequencies. Mostly obsolete as of September 28, 2017. 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. An additional benefit of MURS radio frequencies are the PL codes (Private Line codes) which are sub-audible tones that allow users to operate on the same channel without hearing chatter directed to other users. The ACS-CERT Communications Plan uses the Motorola FRS Channel Numbering Standard. The RMM and RDM radios should not be confused with the Motorola RDV. Set the correct CTCSS or DCS codes (aka PL see HAM Radio 101 – Intro to Repeaters) Press [MENU] 1 3 [MENU] Enter 1 7 9 9 ( remember my example is CTCSS TX tone 179.9) [MENU] [EXIT] 8.) 7.) The most common set of supported squelch tones is a set of 39 tones including all tones with Motorola PL codes, except for the tones 8Z, 9Z, and 0Z (zero-Z). RMV, RMU or RDU series radios (which require licenses to use).

These frequencies were moved from Part 90 to Part 95 and became a new Citizens Band Radio Service (CB) named the Multi-Use Radio Service (MURS). The 151 MHz channels can only be operated in narrow band mode. CB radios may transmit with more power than MURS units may, but communications range is highly dependent on channel congestion and atmospheric conditions. Murs & Co is an extension of my brand as an influencer @mursalison. Multi-Use Radio Service (MURS) is an unlicensed two-way radio service similar to CB but on VHF FM. License free, low cost, two-way communication. The MURS rules are more permissive regarding voice transmissions mixed with data (for example, the Dakota Alert systems) compared to other license-free bands. The Mount Jackson, VA MURS simplex repeater -, 151.8800 MHz MURS Channel 2 151.880 MHz 156.7 Hz CTCSS/PL - Richmond, Virginia (Richmond City, VA) -. The first 83 are the same across all Midland radios, but if you pick code 99 on your MXT105, most other radios will have to disable privacy codes in order to hear you.

Retevis RT-27V MURS VHF Equipment you need for wherever your adventures in life take you. Page 6: Safety This device complies with Part 15 of the FCC SAFETY Rules. The 2 watt power limit is comparable to the 4 watt / 25 watt power limits on the 26/27 MHz RC data frequencies. Old Business Radio Service frequency, heavily used by stores, construction sites, etc. It can be programmed with up to 128 channels. The Cross Mode field allows addressing more commercial modes of squelch operation, such as using different tones or codes for transmit and receive. Short range on-site paging and one-way voice driveway sensors are also found on the MURS channels. PL is short for “private line,” and is what Motorola, the company that developed the CTCSS system called it. By the way, you may hear CTCSS tones sometimes called PL tones. Others, like the MXT105, have 104. The Commission defines MURS as a private, two-way, short-distance voice or data communications service for personal or … What Is The Return Policy At Murseworld? Included in Part 95 of the FCC rules (Personal Radio Services) along with the more familiar services such as CB, FRS, GMRS, etc. The MURS rules specifically permit use of all 5 MURS channels for telemetry, data links or telecommand.

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. Most everyone has seen the small hand-held walkie-talkies that operate on the FRS (Family Radio Service), the best example of this are the small Motorola Talkabout Radios marketed towards family communication. Why Use PL Codes and Tones Why do we use CTCSS tones? ; Old FRS/GMRS Channels. There are 38 PL codes available to each of the five MURS frequencies, which makes for a combination of 190 different MURS channels. 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. Maximum transmitter output power is 2 watts. Maximum bandwidth on 151.8200 MHz, 151.8800 MHz and 151.9400 MHz is 11.25 kHz and maximum bandwidth on 154.5700 MHz and 154.6000 MHz is 20 kHz.
