How to determine if your radio can be used on MURS

5 Upvotes

Per 47 C.F.R. 95 Subpart J - Multi-Use Radio Service:

§ 95.2761 MURS transmitter certification.

(a) Each MURS transmitter (a transmitter that operates or is intended to operate in MURS) must be certified in accordance with this subpart and part 2 of this chapter.

(b) A grant of equipment certification will not be issued for any MURS transmitter type that fails to comply with all of the applicable rules in this subpart.

(c) A grant of equipment certification will not be issued for MURS transmitters capable of operating under both this subpart (MURS) and under any other subparts of this chapter (except part 15).

To search if your radio has been certified for MURS, go to this FCC Website and enter:

  • Grantee Code
  • Product Code
  • Set Application Status to Granted
  • Set Rule Parts to 95J

If there is a record for your device, it is certified. If there is not, you are always welcome to listen to MURS frequencies, you just are not permitted to transmit.

MURS is not unlicensed! It is licensed by rule!

19 Upvotes

"MURS is licensed by rule. This means an individual license is not required for an entity to operate a MURS transmitter if it is not a representative of a foreign government and if it uses the transmitter in accordance with the MURS rules outlined in 47 C.F.R. Part 95 Subpart J." -FCC Website

Licensing "by rule" means you are authorized to transmit as long as you do not violate any of the rules. As long as:

  • Transmitter power output is limited to 2 watts.
  • The highest point of any MURS antenna must not be more than 18.3 meters (60 feet) above the ground or 6.10 meters (20.0 feet) above the highest point of the structure to which it is mounted, whichever is higher.
  • Transmitting on MURS frequencies is not allowed while aboard aircraft in flight.
  • When transmitting in Puerto Rico, Desecheo, Mona, Vieques, and Culebra, care must be taken to not interfere with the Arecibo Observatory.
  • Devices that use MURS must be specially labeled and certified.
  • You do not interfere with any current user of the frequency (especially legacy part 90 licensed) [Listen before transmit]

MURS antenna booster

4 Upvotes

Hey guys I'm very new to radio of any kind. My boss recently gave my team and I a set of 6 Retevis RB17V radios. They work pretty good, but I'm looking for a way to improve the range of them. We exclusively use them in our cars so a vehicle mounted antenna is definitely an option. I have done some Googleing and have seen a lot of different options with different frequencies and things. I believe most of them are geared more towards HAM radio though, or CB. I figured talking to some experienced people who have possibly already dealt with this problem would probably be a smart play. So any information would be appreciated. Thanks!

VHF marine antenna

2 Upvotes

There seems to be a pretty small selection of MURS specific gear out there, since both marine radio and MURS are VHF, could I just set my sights on a well rated marine VHF antenna instead of all these glorified dual band antennas? From my little knowledge of radios something tuned to only one band would perform better...?

Trying to get signal in and out of a metal building and not spend hundreds on an antenna 🥲

TLDR: hooking a murs certified radio to a VHF marine antenna, will it work well?

Radio over IP via MURS

2 Upvotes

Based on the very sparse amount of information outside of going lawyer mode, it appears this is allowed...?

I am thinking of piping MURS into mumble to allow for long range MURS communication.

Would this count as a repeater though? It's not being repeated via MURS, just IP.

Help buying my first MURS radio!

5 Upvotes

Hi!

I'm interested in slowly getting into HAM. I only own a Baofeng right now, and since I'm not licensed I can only listen.

That being said, right now I'm looking for a solution that doesn't require anybody involved to get a license (even if it's only GMRS). Hence why I'm here!

Here are the names I've seen (in no specific order):

There are honorable mentions (RB17B, RT21V, Wouxun KG-805M MURS, ...) but it's even harder to find relevant information on these.

My first question is: is there any reason I would want to buy the Icom and spend ×4 on it?

When it comes to the MU-5 vs. RT47V, it sounds like to me the main differences are:

  • RT47V is waterproof
  • RT47V is "fool proof" when it comes to using it (given the lack of controls)
  • MU-5 receives other signals on top of MURS
  • MU-5 is "programmable" on the field
  • MU-5 doesn't require a cable to do basic programing

They otherwise look very similar. Anything I missed?

Thanks in advance for your help!

Wide band range building to building

2 Upvotes

I wanted to give a data point that wide band on channel 4/5 as permitted does not have close to the same range as narrow band on ch1-3.

This is probably obvious facts for the hams, but I cannot find a good guide that says whether wide or narrow performance is better in VHF, so this is my findings going across a fairly large property with one building being one with metal siding, essentially being a Faraday cage.

MURS Reigns Supreme

7 Upvotes

Sure, you can do a lot with both ham radio and GMRS, and I've been licensed and used both for decades. But with MURS I don't have to use a Callsign that will tell listeners instantly who and where I am. So that's what my family uses most of the time. GMRS would be much better is it also had VHF Frequencies but I'll stick with MURS for family communication and adventuring.

Wide Band vs narrow

4 Upvotes

Is there a good guide which discusses when to use the green / blue channels vs the narrow band channels?

Very new to MURS, trying to properly implement it as safety/security radios at my church campus consisting of three buildings fairly well spaced apart.

As I understand it the closer we get to UHF the better range indoor will be? MURS data really seems to not be as proficient as GMRS, etc. Ugh how nice it would be if business GMRS licenses still existed, having 30 volunteers each get an individual license would be a mess to properly adhere to FCC laws...

Amazon fire stick giving off interference at 151.820mhz?

2 Upvotes

I enjoy listening to my radio in scan mode, and often have it running in the background. Everytime I interact with my fire stick the aforementioned frequency (which is normally used by the local Sam's club) lights up with static until I disconnect the fire stick from the network or return it to standby mode. Anybody have any ideas what specifically is causing this?

Can Frequencies From Other Radio Services Be In A MURS Radio?

I have read that the FCC prohibits GMRS radios from having frequencies from other radio services in it.

Can a MURS radio legally have frequencies from other radio services in it?

Looking for 2.5mm earbuds

0 Upvotes

Short version: Does anyone know of good, 2.5mm, earbuds that can be used listen-only with a Retivis RT27V radio?

Long version: I'm part of a volunteer church security team, and we're planning to start using Retevis RT27V MURS radios so that the guy watching the security cameras can easily direct responders (while dialing 9-1-1 and still watching the cameras) instead of having the guy watching the cameras have be the first responder (which would potentially delay the call to 9-1-1).

Being all volunteers, I need to make things easy or guys won't bother. I picked up a 10-pack of Retevis earpieces, but those are just too complicated with guys needing to clip them on in multiple places. I need something where the responders can just grab a radio, throw the radio on their belt or in a pocket, put in an earbud in, and sit down to enjoy church service with their families. If it's complicated, they won't do it.

I'm having trouble finding 2.5mm earbuds. The team is initially going to try with 2.5mm to 3.5mm adapters but it seems like those are just an extra connection that could come loose.

It's probably better if they aren't the clear "secret agent looking" earbuds just so it looks like we're listening to music during the service instead of looking like we're a security team.

Would a Motorola RMM2050 be a good radio for riding quads if I got a murs outdoor antenna and maybe an external antenna for the radio? How much range do you think I could get? It’s mostly an open field.

I am looking for a MURS radio, and came across these two. Any reason for the BTECH V2 to be double the price or is the radioddity just fine? I can't get a solid answer since it seems like MURS is not too popular.

Anyone with experience know a difference between the V10MR and V3MR? As far as I can see they are essentially the same radio, with the V3MR being newer, slightly smaller, and having a bigger battery.

It’s a great, sturdy little radio. Weather band and broadcast FM make it even more versatile.

WARNING: Retevis RB27V illegal for MURS usage - false advertising

5 Upvotes

Retevis advertises and sells the RB27V for MURS usage on Amazon. At $60 for for this seems to be an awesome deal. It even has the FCC symbol and shows 2ASNSRB27V as the FCC ID. So everything looks great.

Unfortunately no. The FCC database does not have the FCC ID in their database. I checked with Retevis and they acknowledged that this radio isn't allowed on MURS.

Top-Tier MURS Handhelds: Icom V10MR vs. Motorola RMM2050 vs. (?)

4 Upvotes

Hello!

1) What is the best not-made-in-China handheld MURS transceiver?

2) I have my list narrowed down to the Icom V10MR vs. Motorola RMM2050, but if there is something with better receive sensitivity specs/more durable...I want to know about it!

3) I would also like to know whether the Icom or the Motorola has the more durable antenna mount?

a) The Motorola has an SMA male

b) The Icom has a J-type

➡ Is one of these more durable...than the other...?

4) There *do* seem to be aftermarket antennas available for the SMA style:

Link Two
