What are the 5 MURS frequencies?

Can anyone use MURS frequencies?

No licenses are required or issued for MURS within the United States. Any person is authorized to use the MURS frequencies given that it: Is not a foreign government or a representative of a foreign government.

What are the unlicensed frequency bands?

The US Federal Communications Commission (FCC) has three primary frequency bands designated for unlicensed operation. Unlicensed means the operator of the radios does not need to file directly with the FCC to use the radio. The three frequency bands used for this in the U.S. are the 900 MHz, 2.4 GHz and 5.8 GHz.

Which is better GMRS or MURS?

GMRS operation requires an FCC license. 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.

How far can a MURS radio transmit?

These MURS intercoms can transmit up to several miles, and perhaps more with an external antenna depending on the terrain and height of an antenna (can be up to 60 feet above the ground). One benefit of VHF wireless radios is that battery life is almost always better than for similar UHF units.

What MURS channel does Walmart use?

MURS channels 4 and 5 usually serve Walmart as well as Target. Five MURS frequencies can be found at this radio.

Can a Baofeng talk on MURS?

You can use a Baofeng UV-5R walkie-talkie to listen to any GMRS, FRS, or MURS radio but you will need to convert the channel number of the GMRS/FRS/MURS radio into a frequency that you can enter into your UV-5R. See the video at the bottom for the steps.

What are U.S. calling frequencies?

Across all of North America, the National Simplex Frequency (also referred to as the calling frequency) is 146.52 MHz. In areas that use 15-kHz channels, the adjacent channels are 146.535, 146.550, 146.565 MHz, etc.

What is Murs blue dot?

The MURS band consists of 5 MURS frequencies which were previously part of the Business Band, known formally as LMR (Land Mobile Radio service), and two of which were known as the “Color Dot' frequencies (Blue Dot & Green Dot).

How far will a 100 watt FM transmitter reach?

If an ERP of 100 Watt is used, it is very likely that 20 kilometers of range will be reached because a 100 Watt ERP is able to propagate a strong signal as far as 20 kilometers. If an ERP of 1000 Watt is used, it is very probable that the signal will reach 20 kilometers, and it will also penetrate eventual obstacles.

How far can a 10 watt radio transmit?

Thus the typical ranges with around 400 MHz frequency range with 1 W transmitter power are up to ~30 kilometers and up to ~80 kilometers with 10 W transmitter power.

Are MURS radios good?

MURS radios are a great way to keep up short-range communications when the cell-phone network goes down. With MURS you can call your neighbors for help, or keep up the communications while patrolling your area. MURS radios are simple to use. Just pick a channel and you're set.

Can CB talk to GMRS?

FRS and GMRS radios are not cross compatible with other types of consumer radios. CB radios operate on the 11 meter AM band, and have their own channel and frequency assignments.

How far will a GMRS radio reach?

Typically though, most GMRS radios use between 1 and 5 watts of power. Their range is a bit better than FRS radios, with typical hand-held devices being somewhere in the 1-2 mile window. Some mobile units with higher antennas can have a range up to 5 miles.

Which is better CB or GMRS?

While VHF radio waves – including CB – typically travel farther in rural settings, GMRS's power advantage overcomes UHF's slight range disadvantages to give longer range in most scenarios. GMRS may work better in wooded areas, since UHF radio waves can easily travel through small spaces.

What radio frequency do walkie talkies use?

Two-way radios (or walkie-talkies) generally operate in the 136 MHz to 900 MHz frequency range, as defined by the FCC. This is an overview of the various services and bands of frequencies. For a complete guide to all the officially assigned frequencies, you can refer to the FCC Online Table of Frequency Allocations.

Which are the free radio frequency bands used for Wi-Fi?

WLAN Frequency Bands: The 802.11 working group currently documents use in five distinct frequency ranges: 2.4 GHz, 3.6 GHz, 4.9 GHz, 5 GHz, and 5.9 GHz bands. Each range is divided into a multitude of channels.
