I believe there is not a 5 watt regulatory limit on handheld portable GMRS stations on either the 462 main channels or 467 MHz main channels.
Yep, I tend to agree with Sshannon on the power limit on Handhelds. There are few GMRS FCC Part 95 E portable that have been tested and put out 6 to 8 watts, but I don't remember the manufacture. I know that it's not Motorola or Midland. It was one of cheap Chinese radios. Some of those radios have good reviews, but overall nothing beats the Big guys, Icom, Kenwood or Motorola.

I'm going to express my thoughts about the part 95 rulings.
To start off, when I applied for my GMRS license, I requested a copy of the rules so I could have em on hand in my laptop. How ever, the handheld transceiver regard to limited power on it said 5 watts. Others today are arguing that truth.
Secondly, people are saying that they have the rights to use amplifiers with the GMRS mobile, base and handheld. I'm told that nobody can use a amplifier. The copy of the part 95 rules was updated December 22, 2023.
Either way I'm complying with the rules and IMHO I believe that the FCC should crack down on this issue.

I guess there are some rules and regulations within FCC Part 95E that can be confusing. On the other using a 5-watt HT could be connected to an amp, providing you're only using channels 15 through 30 and not exceeding 50 watts. Channels 01 through 07 may not exceed 5-watts. Of course, most handhelds that has the full 30 channels, won't be so easy to use, because channel 08 through 14 is restricted to a half watt and must have permanent antenna.

Why does the FCC allow people to see name and address with the call sign look up? It seems to me it's a violation of personal privacy. I know a governor got in trouble for releasing the names and addresses of CCW holders so how can the FCC get away with it. They could at the very least block your home address and just show name and maybe city and state but the home address shouldn't be posted.
What do y'all think? How can we make them change this?
According to my knowledge, the FCC gives individuals an option, to use Physical Address or a POB. As far as other people seeing Names. That one, is over my pay grade.

I really enjoy both of my BTECH GMRS PROs, but I wish BTECH would have included the ability to monitor digital systems. I realize the primary use for FRS / GMRS simplex and repeaters. However, I do enjoy the ability to monitor Railroads and Walmart associates, but sooner or the Class 1 RRs will be switching over to IDAS/NXDN and unless I want to keep monitoring Railroads, I'll have to carry to different radios again.

Assuming that you know for sure that there's no GMRS repeaters in your general vicinity. Yeh, I would put one up, even if you discover there, are repeaters in the vicinity that you weren't aware of before. I would still put up a GMRS repeater, because you may want to help out community while keeping the lines of communications up when others are down. One of a few differences between Amateur Radio and GMRS. To put Amateur Radio Repeater, requires frequency coordination and since GMRS has only 8 repeater pairs, choose a pair and play ball.

It wasn’t a waste of my time. As I answered above I’ve never seen any issues with my wife’s mobility scooter.
Yep, I got it. I just put that particular question on the table, because I read my owner's manual, I was curious to know why the manufacture emphasize Don't use Two Way Radios on scooters when I haven't had any issues. Doesn't really say anything about the use of cellular phones, even with a Bluetooth hands free device. I'm glad to hear that you haven't experience any issues with your wife's mobility scooter. I can only what MTD is printing in their for Electric Lawn Tractors and industrial mowers.
Thank you

Maybe I have already answered my question. Although I haven't any issues so far, I just wanted to see if anyone else had issues with using a 2-way radio or Cell Phone while operating a Mobility Scooter. I guess manufactures don't really do too much on the test stage when it comes to Activities or Tasks that user of the scooter is doing. My only experience as far as RFI while operating scooter is, a few retail stores RF anti-theft alarm. Well I hope I didn't waste anyone's time with an odd question.

That's a very good question.
Lately the auto manufactures want to eliminate AM radios from their vehicles. I strongly suspect there is much more to it than a simple cost cutting measure. I'm even more suspicious when an EV is involved.
My professional work experience involves designing high power switching inverters for metal heating at high frequency. I know first hand just how much electrical RF trash these things generate. I also consult with a buddy who does work over the years on EV motor drives, very similar in design principle to what I do. In his case they have to do extensive EMC, electromagnetic compatibility, testing.
The AM radios are amplitude modulated receivers in the frequency range of 550KHz to 1600KHz. Some of the EV motor drives operate up to 150KHz in some cases. The harmonics from the switching waveforms can easily end up in the AM radio broadcast band. I think the manufactures just want to eliminate the AM radio option rather than spending gobs of money trying to shield the motor drive inverter electronics so it doesn't trash the radio in the dash. If it's not there then there is no complaints they have to deal with fixing.
Thank you for giving me an answer! I was just trying figure out you typical Power Wheelchair or Mobility Scooter would issues with the use of Two-Way Radios.
The majority of Airports or Railroad Terminals use Terminal Carts, which are Electric Vehicles. Of course, the operator uses their 2-way radio. However, I'm not sure if I have facts right when it comes to a two-way radio while moving. Does it effect, all electric vehicles or only wheelchairs and mobility scooters??
Like I said in my question, I know that don't have any issues with talking and moving at the same time. I wouldn't use an old AM CB, because AM would definitely pick up motor RF and add hum.
If I'm rambling on, please shut me up. I apologize for sounding like why I asked this question in the first place. I

Specking from someone who uses a Mobility Scooter and has a bit of knowledge of RF and RFI, but I tend to ask how my experience is different than the manufactures.
I been using Hand Held Transceivers while driving my scooter for years without RFI to the motors. Of course, Manufactures warn owners don't 2 - way radios, because the RF from the radio can effect. Individuals use their Cell Phones while driving, Of course, they're not driving on streets and interstates like regular vehicles. then while crossing heavy traffic streets, I guess no one should holding anything, but the Tiller. I never had any issues that caused malfunction to the motors on any scooter that I drove.

Would it be legal to use MURS (with correct band width an power output) to link two GMRS repeaters? Opinions?

I just reviewed my reply and sounds like I've been either have been drinking or my mind was on a coffee break. Of course, questions such as this one is asked once in a while. As for the question posted by gscanter 15 Feb of 2023. What I meant to say, according to the FCC's Rules and Regulations. The short answer would be a Big No, because the FCC intended for MURS to be used for multipurpose, either for commercial use or non-commercial use. According to the FCC's Part 95 J, it is forbidding to crossband MURS with GMRS simplex or repeater. However, there have been individuals who have set up temporary crossband simplex systems using MURS and GMRS channels, which still violates Rules & Regulations.

A while back I posted something about a Shortline Tourist Railroad utilizing FRS for communications. Of course, I assume that the office staff concession staff use it, not the Train Crews. Although Shortline RR operate differently than Class One Railroads. I notice the Turtle Creek RR in Pennsylvania listed 462.5625 w / PL 67.0. For the majority of those with less knowledge of FCC Rules & Regulations, I'll bet they have interference with just anyone who use that same channel to talk to their family members on board train or around the railroad property.
Happy New Year !

There's post on just about everything that FRS Radios can be used for, but I haven't read about FRS Radios in the world model railroading. Some years ago, my friend took up to the NYMES and I noticed the club members were communicating using FRS. I wish I had scanner to pick up the comms, I imagine they were operating prototypically, because many model railroading clubs try to operate realistically as possible. Right down to using NORAC RULES and FRA RULES.
There has to some members on this forum who not only into GMRS, but as model railroading enthusiasts. I just see my Jim and I if FRS was available back in the late 80's early 90's, we would have a ball. Because as a Rail Fan, the overhead catenary was murder on AM CB. We attempted using 49mhz, but the transmitting power and too obstacles to block the line of site.

Hope everyone enjoyed their Holidays. whether it's Christmas or Hanukkah. I sure hope everyone had plenty of time to reconnect with Family and Friends. Knowing with the FRS/GMRS radios, I noticed they're becoming popular with model railroad clubs. Of course, I rather use MURS for model railroad, since the prototype operates in the VHF spectrum.
Well Happy Holidays Again!

I shouldn't have said who cares whether the radio is typed accepted or not. To me, it just seems odd when older commercial part 90 radios can't be repurposed for GMRS. Amateur Radio Operators snatch up those radios like toilet paper at HAM FESTS. Then again, those recently new FCC Part 95 E. Rados are easier to program on the fly. With Kenwood or Motorola, programming software and cables aren't easy to obtain, unless you know where to go.
Happy Holidays to All !

My True Opinion on the BTECH GMRS PRO. What can I say, the GMRS PRO? This Radio has its pros and cons just as all radios. Yes, I do sincerely believe the GMRS PRO is an excellent tool that is useful for any application The ability to monitor other radio services is a plus, especially when there's a Public Service Events or a Disaster Relief Operations. Let's face it, in a SHTF, you going to want to know if your message is being relayed, because not everyone has an Amateur Radio License. You going to want to monitor Amateur Repeaters to receive information even when you don't need to relay a message. You can receive the message intended for you before the operation who you communicate can relayed the message to you.
As far as for Railroad enthusiast, it great now since the majority of Class 1 Railroads haven't switched over to IDAS/NXDN yet. There may be Railroad enthusiast GMRS clubs out there that take advantage of repeaters and simplex channels to talk while watching rail action for different locations. Of course, the same thing on the Amateur Radio Frequencies. I guess have a radio to monitor and keep taps on trains with fellow railfans makes GMRS or Ham a Great Hobby.
If BTECH came with a GMRS PRO Plus Digital Receive for NXDN and DMR, I would purchase one.

Wow! OVER 20 years!? I am very impressed!
I know you could care less about how long someone has been licensed. I probable sound like more like confused HAM instead of just a Sad Ham. My new year's resolution for 2024 should be to research topics before for forming an intelligent opinion. Hope you keep making good videos for YouTube, because in a way you remind me of what uncle Ray use to say. Don't give me S**T, just show it.

Because they are so close to the repeater input frequencies. It's to minimize potential interference with repeaters.
(c) 467 MHz main channels. Only mobile, hand-held portable, control and fixed stations may transmit on these 8 channels. Mobile, hand-held portable and control stations may transmit on these channels only when communicating through a repeater station or making brief test transmissions in accordance with § 95.319(c). The channel center frequencies are: 467.5500, 467.5750, 467.6000, 467.6250, 467.6500, 467.6750, 467.7000, and 467.7250 MHz.
(d) 467 MHz interstitial channels. Only hand-held portable units may transmit on these 7 channels. The channel center frequencies are: 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, and 467.7125 MHz.
They are only .0125 MHz away from the repeater inputs.
That makes sense now! Happy Holidays

Hello, I am a GMRS newbie, only having my license for 6 days. What is the purpose of channels 8-14 being they are only 1/2 watt? Makes no sense to me, seems useless. What kind of range can one even get on 1/2-watt channels? Another question, more out of curiosity, would someone still have to provide their caller ID if they were on those channels?
That question of yours about channel 8 through 14 makes sense. I read the FCC Part 95 subpart A, B, & E and I still don't see the reason for half watt on channels 8 to 14. I had both my Amateur and GMRS for 20 years. I know many other licensees would say I wonder how Adam was able pass an exam and still come with comments that don't makes sense. I apologize for sounding uneducated, but I able to leave my cents.
Happy Holidays to All !

Comparing services in UHF HAM vs GMRS. Both services have their pros and cons, but each service gets the same job done. True an Amateur Radio Licenses only authorizes the person who passed his or her exam and GMRS licenses authorizes the entire Family. A CB would do just about the same as GMRS on simplex and even about the same with the audio quality, now that FM is legal on 11m Band. In a real SHTF, the majority of GMRS repeaters, like Ham repeaters will be down or in service for BUCC, with the Local ARES or CERT groups. So, using any repeater, whether Amateur or GMRS will be like trying use a Landline or Cellular.

Looking at getting a mobile radio to install in my truck, leaning on Btech from talking to a few others but haven't decided on what model. Any recommendations are appreciated
If I were looking for a good GMRS mobile, I would look at the used or new old stock commercial radios, such as Motorola CDM 1250 or Kenwood TK-series. These radios may not be typed accepted for GMRS, but they can easily be modified for GMRS. Don't get me wrong, BTECH WOUXUN and MIDLAND have good radios, but ICOM KENWOOD MOTOROLA and VERTEX also make excellent uhf mobile radios for GMRS and other bands.
Who really cares if the Radio is Part 90 or Part 95 E? As long the radio properly tuned for the GMRS, the FCC wouldn't object individuals using old Part 90 Radios.

Where are the NW Ga repeaters? I’m trying to become a member!
I'm not sure where the NW Georgia Repeater area, but I would keep asking around. I'm not too sure about certain GMRS repeaters my general vicinity, I know I have permission to use them, but only one I am not sure if I can get on the National Net.

I've caught some very sporadic DMR traffic on channel 18 by me. It was a few transmissions during the day lasting a few seconds each. I haven't heard it in many months. I suspect either somebody miss programmed a radio, or did so deliberately. In any case it stopped and I suspect the local FCC might have had a hand in ending it.
There was a YouTube Video where 2 individuals were using an FRS channel in DMR format. Of course, I have to admit that sometimes I test DMR Radio using an FRS channel. I forget the manufactures, but there is DMR FRS radio out there.

This Topic of using FCC part 90 equipment on 95 A service seems like a never-ending saga. I'm guilty of using Motorola Maxtacs and HT 1000s on GMRS prior to the recent update in 2017 taking GMRS from Part 95A to Part 95 E. Of course, someone who just get their GMRS License will tell me the GMRS was never Part 95 A. I know I probably right about that. I mean someone disagreeing from about GMRS use to be Part 95A. I wonder why the FCC changed it from Part A to E. FRS is still found in Part 95 B...
I apologize in advance for rambling on nonsense, but those same folks, sound like hall monitors. I mean when it comes to using used or new old stock radio that are part 90 certified for GMRS.

Hey All,
Just joined the group and looking to learn as much as I can. Call sign WRZQ354, just picked up 2 Baofeng UV-9G. Configured a few things in Chirp. This is a little more confusing than I thought it would be, but I am fairly technical and hope to be up to speed soon. I plan on looking at the repeater map here and hopefully find permissions and willing sole for a radio check.
One question I do have is when talking just between these 2 radios for family, do I need to program the channel for a tone or squelch or can I do without. I guess if i do use a tone I would want to program each radio with that programmed as a favorite(not sure if that is the right term)????
Glad I found this group.
Thanks All
Murph
Hope you and your family make use of your GMRS license, because you'll want to get accustomed to using radios, especially when cellular service and land lines are down. Not Just during crisis, because even normal conditions, a Cellular Phone will not work due to lack of towers. On High Power Channel on simplex you can expect a range from 3 miles to 5 miles on an HT and about 8 to 10 miles even more on Mobiles. That's depending on your surroundings and the antenna being used.
Take Care!
Don't stop asking questions, because that add tools to your Comm Plan.

I have to admit that I was wrong about antenna requirements for GMRS. According to my knowledge, the BTECH GMRS PRO was supposed to have a permanent antenna, due its data capability. Maybe I'm still wrong and should get out the Hobby Amateur Radio and GMRS if I seem to be wrong all the time.
