Hum.... If it's operating illegally then I suppose they really couldn't complain if it got hijacked by local GMRS users. If they did the FCC might take more of an interest in it and ask a lot of questions they would rather not answer. Their other choice is to shut it down and apply for a legitimate business frequency and move it there.
And SDR dongle with the decoding software, or one of those D878UV's using the digital monitor function, will show you all the color codes, slot numbers, talk groups and user ID's on the repeater. While the D878UV might not be that great of a radio the digital monitor feature is one of it's very useful one's for getting info on unknown DMR traffic.
It's encrypted DMR. About all you can see with SDR are the headers at start of tx and they are using GPS tracking and reporting but can't see the data. It showed up 2 years or so ago and drove a really strong GMRS repeater off the frequency. A few other GMRS repeaters have tried using the frequency only to give up after a few weeks and move to another frequency.

You sure it's really operating illegally? Remember before the 2017 rule changes business could get a GMRS license. So long as the business has maintained their license, didn't let it expire, they can continue to renew it and operate LEGALLY. The only way to find out is locate the business in the FCC's database, assuming it exists, and if so is their license
It is not listed in the FCC database, at least by frequency. The local Motorola shop is one of those that filed a complaint. It has made .700 unusable in the area.
The City of Tampa does have a legacy license on .625 that ID's every 10 minutes but in 3 years I have yet to hear anyone use it. I have a list of all legacy licenses by zip code if anyone wants it.

And I believe that the FCC has issued some experimental waivers to some repeaters to allow them to test digital on GMRS, so we cannot immediately assume that a repeater with occasional digital users is in violation of.
I understand that. I don't know or even care if the P25 repeater has a waiver. It's used so infrequently and if you have tone on receive you won't hear P25 at all. It doesn't bug me but like I said, some folks go banana's the when hearing it for the first time.

Learn to live with it. In my area there is a business operating a illegal DMR repeater and has been for a few years. It's been reported to the FCC by numerous folks, yet it's still there.
The best repeater in the area is running a Motorola Quintar repeater that can work with analog or P25 digital. The info to use P25 is on their website if you have a P25 capable radio. 95% of all traffic is analog though. I hear P25 maybe a total a 5 minutes a month. It freaks out new users and the FCC rule hounds. For such a nice FREE repeater, it's a small annoyance I can live with.

Hey Guru's I'm currently in Cashiers, NC listening to gmrs channel 17 and am picking up chatter from Atlanta, GA. I don't understand how as I had received permission from repeaters in my area of Walhalla, SC trying to bridge the gap between the two but am unable to. How are they getting this far? is it a club?
The only way I've been able to connect from Cashiers to Walhalla is thru Business band repeaters on 461.7250 .
I gotta know how they are making the distance!
Probably a part of the North Georgia GMRS Network

While it is a nice feature to have two speaker ports on the KG-1000G, it would have been easier for everyone if there was only one port.
I wouldn't have bought a 1000G if there was only one speaker output. While the OP is wanting to merge both VFO (in Wouxun speak "Area") speaker outputs into one speaker, a lot of us want to have each them separated. For my base station I have a external speakers on ether side of my computer monitor and a different scan group setting on each side of the radio. I can quickly tell without looking what side of the radio is receiving based on what speaker is outputting. It's kinda like having two radios in one.

I'm using a mono Y adaptor
Here is an easy way to test the Y-adapter. If it is working on one side of the the radio, swap the speaker out cables on the radio and see if the side that was working stopped and the other side starts working.

My old Jeep is noisy. I added a Lido headrest speaker and used a 3.5mm "Y" adapter to connect the speaker to both out puts as directed in the manual. I only get output on the external speaker to area b, no matter how I have the speakers set on the radio (radio, mic, both)
What is going on with this radio?
If I had to guess you have a stereo to mono 3.5mm Y adapter. It needs to be a mono to mono or stereo to stereo 3.5mm adapter.

Our clinic has dropped its GMRS handhelds, so now we have a VXR-7000 sitting around. Is there a way to make the VXR-7000 use a ham frequency instead of the GMRS frequencies? When I try to create a channel with a frequency lower than 450.000 it reverts back to 450.000. I don't want to just throw this repeater out... Thanks. Don, KK7EV.
I'm pretty sure you can set up a VXR-7000 for 70cm ham band by accessing the repeater with the PC software in dealer mode (-d option). You can search here on how to do that.

This chart is inaccurate and is mostly confusing and contrary to the rules in Parts 95.567 and 95.1767 in respect to RF output power levels for both the FRS and GMRS radio services. The rules state that Channels 1-7 are regulated to 2 watts ERP for non-licensed FRS service and 5 watts ERP for licensed GMRS service. The left chart indicates channels 1-7 for both FRS & GMRS are regulated to a .5 watt and that is incorrect. The right chart indicates that Channels 8-14 are regulated to .5 watt ERP for FRS and that is correct, and 5 watts for GMRS and that is incorrect, all transmitter transmitting on these channels are regulated to a .5 watt ERP, regardless of the two radio services.
The left chart indicates that channels 15-22 are regulated to 2 watts ERP and that is correct.
Both charts indicates that the 462 (462.550, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, and 462.725) and 467 (467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700, and 467.725) Main Channels are regulated to 50 watts and that is correct, except for the 467 main channels, they are regulated to 15 watts for fixed class station operations.
The 50-watt output is not limited to the measurement of antenna ERP for the 462 & 467 main channels. The 50-watt output limit is the measurement of power out of the transmitter before the antenna and there is no limit of the ERP of the antenna.
I like the chart for how is visually displays the channels and frequencies, didn't even look (or care) about the power limit thing. I've got a similar chart for shipboard communications in kind of the same format, it's just the first one I've seen for GMRS.

I just saw a YouTube video on new aftermarket firmware for the H3 a hour or two ago. One of the things claimed is that it is programmable/firmware updateable via the USB-Type C port. He shows a video on how to do just that. I have no idea if it works on the GMRS locked version or not. The 3rd party firmware actually looks half decent.

Good to know on the lookup.
On the address, thing I notice the first one (that redirected) has a typo in it (mygRmrs dot come)...is that the address you entered that redirected? I have seen a number of pages that play off of misspellings of popular sites that will funnel into those scam/popups/malware type pages, but a little worrying that edge doesn't pick up on that where chrome does.
I was testing for the OP on the lookup issue and didn't want to log out of mygmrs in Chrome (to be honest, I don't remember my password but have a good idea - someday I need to remember to dump my saved passwords from Chrome before it's too late). I use MS Edge maybe a few times a year, more for testing if a site has problems in Chrome than anything else. I typed "mygmrs.com" directly in the address bar - didn't search for it when the scam site came up. I exited Edge, tried in Chrome and it was fine, went back to Edge and it worked fine. Like I said, most likely a issue on my side.
I'm just used to uBlock Origin in Chrome blocking such sites for years, killing the commercials on YouTube, etc. It's a shame Google killed it from the plugin store. It still works, but don't know how much longer.

This will be the key ^^^
If it requires being logged in to use the search, drop your callsign in the thread, OP, and one of us can look for you.
Can't remember your callsign either? FCC search to the rescue! https://wireless2.fcc.gov/UlsApp/UlsSearch/searchLicense.jsp
I just tired checking my callsign on the callsign lookup tool from another browser without being logged (or ever have been) into the site and it works just fine. It showed my username under my callsign.
BUT.... I only Microsoft Edge on rare occasion (what I used to test). I typed in mygrmrs.com in the address bar, it redirected me and brought up an obvious Windows security scam site. First one I've seen in years. I clip-boarded the redirected address and pasted it into Chrome, it blocked it as a malicious site. Tried mygmrs.com again in Edge and it worked fine. Probably a issue on my end but spooked me a bit.

Ok, I'm not an expert by any means of marine frequency allocations. But is what they are doing legal?
Yes... At least on 467.550 and 467.575 (the input freqs of GMRS repeaters 462.550 and 462.575) per ITU agreement. The sad part is they are allowed and encouraged to run a shipboard repeater output on those two GMRS repeater inputs but at a 10MHz lower split instead of +5MHz GMRS uses.

One of my area ham radio clubs (they also run a great GMRS repeater) runs an event every month at a local park. Every month is a different theme, one month is QRP and the next may be GMRS but they always encourage GMRS users to come out and participate and always have a GMRS station setup. A few months ago they held a fox hunt theme with three stations. One GMRS, one 2m and one 70cm at different locations. I was out of town but heard they had a lot of fun.

The way I hear family ID's on GMRS goes something like this:
First transmission: "(callsign) unit 1 to unit 2"
Second transmission (responding radio) "unit 2 go ahead"
Conversation between the to units but no ID since they know each other
Last transmission "(callsign) clear"
I don't think I've ever heard a family ID ever go on beyond 15 minutes.

Check out the Signal Identification Guide website at https://www.sigidwiki.com/wiki/Signal_Identification_Guide
In particular the DMR, NXDN and the different P25 modes. Sound examples are on the webpage.

Being new to this I could quite possibly be doing something wrong. I was scanning channels and picked up the conversation on repeater 21. I used the Wouxun software to program the repeater name and frequencies as RX 462.7000, TX 467.7000 with input tone.
You should have tone on output of 467.700 not the input. The input tone of the repeater is the output tone of your radio.

I did not explain myself well enough, thanks. I want to program a non-standard repeater split, not the +5 Mhz standard!!
The largest repeater in my area (462.575) has two receivers, primary on the standard +5 (467.575) and a secondary on 467.725. The repeater overlooks the port of Tampa and gets occasional interference on the primary input from ship traffic and they have shut it down. Unfortunately it confuses a lot of folks and a lot of radios (Midlands for example) don't support anything other than a +5MHz offset so they are unable to transmit to the repeater but receive it just fine. My Wouxun's (KG-1000 and KG-935) will allow for a different offset - as long as the TX offset is a GMRS frequency (including frequencies not assigned for repeater inputs like 467.6125) but a lot of radios don't.
If your radios have dual scan or priority watch, what you can try (as long as the TX frequency is a standard GMRS frequency) is setup TX on whatever you want and RX as a 2nd channel on the dual scan or your priority watch channel.

Keep in mind that maritime users ARE allowed (even digital!) on the GMRS repeater input frequencies of 467.550 and 467.575 per ITU (not FCC) regulations but not the outputs of 462.550 and 462.575. They may affect (as they do in my area) the input of a 550 or 575 repeater mixing in with legit traffic even if on a different tone causing a bit of chaos on the output.
Digital Signals on gmrs repeaters?

Not in this case. You can tell by the DMR headers it is running a Motorola system.
