I imposed this restriction for a few reasons: Depending on the skill level of the person wishing to join the network, it may take a lot of hand-holding to get them set up. Unfortunately a lot of people want something completely plug-and-play and that's impossible when you have different radios being used. If we allowed every individual to purchase a kit and had to spend time helping them get their audio levels right and open up the ports in their router, we'd have to charge way more money just to cover our support time. When you have hundreds of nodes trying to link together, you end up with problems with audio loops, poor audio quality, audio level problems, and too many people connecting and disconnecting during a net. This becomes very disruptive when nodes announce the connect and disconnect events, and this makes the net almost impossible to listen to. It goes against the spirit of GMRS and two-way radio in general. If you want to just sit at home and listen to the network, you don't need to use GMRS as an RF link. You'd be better off using a bluetooth speakerphone to your PC or just listen on your phone. I personally don't believe GMRS is meant as a personal hotspot service. Use the RF to cover a wide area, more than just your house. When it comes to expending the least amount of effort for the most amount of return, the best option is to prioritize high-level repeater systems for joining the network. If we have to spend an hour tuning audio for someone and their repeater covers maybe 50 users, that is much more efficient than having to spend 50 hours of effort to get the same people on the air each with their personal "hotspots". If the goal is to sell as many linking bundles as possible, then we'd want to allow simplex nodes on the network. However the goal is to build a robust network, and we really sell the bundles at-cost so we can easily add more repeaters to the network.

There is no forum access via the app. The Tapatalk app should be able to be used with this forum, however, plus there is a mobile web version of these forums when used on a mobile device.

Hey John, can you PM me the info as well? I had both but I think you've changed PLs over time. You can list the repeater as Member's Only so people know it's private.

Welcome! 1) The Midland radios have the ability to enable the 8 extra channels for repeater use. These will transmit on 467.xxx MHz and receive on 462.xxx MHz, whereas the simplex (direct) channels will transmit and receive on the same 462.xxx MHz frequency. In addition to the frequency a repeater transmits, there is also the CTCSS tone (also known as PL tone) which allows a repeater to selectively repeat transmissions from one group of users when others may be on the same shared frequency. On more advanced radios, you would set up a channel for each repeater in the radio's memory, where they would each be one of the 8 repeater channels (i.e. 462.550 MHz), but the CTCSS tone would vary for each repeater. On the Midlands, you need to manually change the tone to use a different repeater. So in the example above, you'd tune to channel 15R (repeater channel) and set the tone in the menu to whatever the local repeater on Channel 15 (462.550) requires. If you go to a new area where there is another repeater also on 462.550, you would stay on Channel 15 but change the tone to whatever that new repeater uses. 2) A repeater will extend the range a single radios has by many miles, depending on the height of the repeater in elevation. If two radios are nearby but suddenly cannot communicate due to the terrain or distance, a nearby repeater located in a tall spot (a tower, a tall building, or a mountain top) will allow those radios to communicate by retransmitting the signal at higher power and at a higher location. UHF frequencies are almost line-of-sight, where two stations can communicate if there is an unobstructed view between antennas. By putting the repeater antenna high up, it will be able to "see" a much larger area and thus extend the mobile units' coverage over the greater area it can "see" from its height. So a radio with a 1 mile range can suddenly get 15-30 mile range if there is a repeater in a good spot high above the average terrain height by having the repeater retransmit its signal at a higher power and elevation. Repeaters have a limit to their range based on this elevation, as the visual horizon distance changes with regard to height above the ground. Since the Earth is curved (flat-earthers will be disappointed), the further away you go from a station, you begin to curve below the horizon and eventually the Earth itself will block the signal. The only way around that is more height, and that's how satellites can have such wide coverage. They are essentially a repeater at an extreme altitude and thus they have visual line-of-sight to a much, much larger area than a tower on the ground could ever have.

Just a caution to be civil here. This thread has the potential to get political fast, and that's not okay here. For casual listening to the protesters, I have no issue with sharing that information. I do have a problem with using that information for nefarious purposes, however. Just like how it's okay to share information for monitoring police and the military within the confines of the law, but once you try to use it for nefarious purposes that goes out the window and becomes a problem here.

Travel Tone is when a repeater enables 141.3 Hz as an open tone for travelers to use when in the area. For example, you could tune your radio to each GMRS repeater channel with 141.3 as your tone, and the repeaters with a Travel Tone are open for temporary use without permission. Good for when you don't have time to program each repeater along your route. ORI stands for the Open Repeater Initiative which was created by Popular Wireless many years ago. It was a way to indicate a repeater is open for any licensed GMRS operator to use without having to ask the owner's permission. These repeaters you can just jump on and use as long as you follow GMRS rules and use your callsign.

Originally "Handie-Talkie" from the old Motorola terminology for a handheld radio (I believe they were the first to have one that "fit" in your hand, so they coined the term). Now HT is more of just a quick abbreviation for a handheld radio in general, many of us aren't thinking of "Handie-Talkie" unless we're REALLLLLY old.

CCR is a common one for "Cheap Chinese Radio" which includes Baofengs, Wouxuns, and such. I think having a list would be good!

For now, yes. We don't want simplex nodes right now because: 1. It kind of goes against the spirit of radio. If you're using a simplex node to just cover your house to talk over the Internet, you don't really need GMRS to do that. 2. Having one node per person adds a lot of complexity and load to the network. It's a lot more that can go wrong and then you have audio issues, announcements or IDs going off, and people connecting and disconnecting a lot. 3. We (mostly me) don't have the time to hold everyone's hand and set them up with a personal node. There's still a steep learning curve to setting up a node if you've never used Asterisk before, and it requires some comfort with running Linux commands. A lot of people don't have that experience and we just can't spend hours on each person for free setting them up. It's much easier to spend time on a single node that is on a repeater with good coverage so you're potentially linking many people together and not just one at his house. We're more interested in covering as many people as possible with as few nodes as possible to keep the overall quality of the network up and minimize problems. Lately we've started to have some growing pains during the National Net where the nodes aren't all cooperating, and trying to fix things with potentially hundreds of new nodes would just be a nightmare. Zello is one avenue I've explored as a way to tie into the network. Zello is a great app but it has several issues that make it hard to adapt to our network. Zello sends the audio to their central servers, then forwards on to the recipient in a non-realtime manner. This is great for ensuring the message got to the recipient and is fairly clear, but there is latency introduced in sending the audio to the client particularly on a poor connection. The problem is people end up doubling over one another. It's still a possibility but it would probably be a single node that people can choose to connect to, rather than many nodes.

So I heard the GMRS network test the other night. Pretty cool!
rdunajewski replied to Kamperdog's topic in General Discussion
Where were you when you heard it? I see you're also from NJ like WRAK968 and I. You may have been hearing his Little Egg Harbor machine or my Mercer County machine. We're working on one in Woodbury Heights as well. It's a network of over 50 repeaters across the US linked via Internet. Everyone is welcome, you just need to be in range of a repeater that is linked into the network. -
New Interfering (IX) Signals - "Baby Monitors" using GMRS/FRS
rdunajewski replied to intermod's topic in General Discussion
I seem to think Retevis has a type-accepted intercom very similar to the one WRAK968 posted. I was digging through the OET site and found it. If I have time I'll go look it up and post it here.- 44 replies

FRS frequency being transmitted on Repeater channel?
rdunajewski replied to Mikeam's question in Technical Discussion
I've seen shady radio shops set people up on FRS/GMRS frequencies illegally, if this is a random repeater you've found and not one you know personally. My favorite was a FedEx hub operating a repeater on the FRS frequencies with a range of like 15 miles or more to cover their warehouse. F-bombs day and night constantly, just shocking crap you'd hear. They thought they had a private channel, meanwhile they were splattering all over FRS. Needless to say the FCC paid them a visit and got them on business band literally overnight. They had a STA grant the very next day for a business pair and their FRS repeater went silent. Not sure if they were fined, but the visit was effective. -
Just tuned into National Net--intrigued, and have some questions!

Just tuned into National Net--intrigued, and have some questions!
rdunajewski replied to a topic in Guest Forum
Hey David, Welcome! You were most likely hearing the Bronx Zoo repeater in NYC. We run a network of repeaters which use Internet for linking them together. Every Sunday we hold a National GMRS Net with a given topic, and everyone who is checked-in is welcome to briefly have the floor in a round-table discussion. We stream our nets live on YouTube, and we also have most of our previous nets available on YouTube. The net grew to be pretty popular and it was taking over two hours most nights to get to everyone. Starting last week, we changed up how the net works so check-ins are handled in advance and we can jump right into discussion to shorten the length of the net considerably. Anyone with a valid GMRS license is allowed to participate, there are no membership requirements. You will need a repeater-capable radio (which the FRS radios you were listening on are not capable of), and a GMRS license. A license costs $70 and covers you and your immediate family for 10 years, making it a great option for backup emergency communications. If you're not familiar, a repeater is typically placed on a tower, building, or other tall place and contains a transmitter and receiver to boost the signals from handheld and mobile radios to increase the coverage range. By linking them together, you can get even further range which is how you're hearing people from across the country. To get a GMRS license if you're interested, you can follow the instructions posted here: https://beta.mygmrs.com/help/get-gmrs-license We also sell repeater-capable radios through our shop: https://shop.mygmrs.com/collections/repeater-capable -
That's true, the licensee is the one responsible. But consider they choose not to ID at all, you as the licensee would probably not be the target of the FCC. Instead, they would be for transmitting without a license (or, if the family members knew they were covered by your license, could be given a violation for transmitting without station identification). Long story short, just make sure they're capable of following the rules before you attach yourself to it. As long as you're confident they will take it as seriously as you do, it should not be a problem at all.

New to GMRS - How to Get Access to Use a Repeater
rdunajewski replied to gmarman's topic in General Discussion
Unfortunately all the Midland handheld radios are simplex only. They know there is demand for repeater-capable handhelds and they said it's something they eventually plan on doing, but they haven't announced any new models with that functionality yet. -
Technically? Yes! As the licensee, though, you'd probably be on the hook for any FCC violations (at least for the kids) but it's not so clear about the adults. As long as everyone is willing to follow the FCC rules when operating under your callsign, yes you can do that even though you won't be present.

Last one was from 2013, time to get with the times. I think this was from 2019. Getting warmer!

I just replied to your PM. Sorry if I missed your email, but didn't log into the forums until just now. I see your email has a typo (wrong callsign) so I just fixed it and emailed a password reset link to you. You should be able to reset it now.
-
Hi Joe, I think I was just emailing with you and you said you were able to register. Just checking if you're all set?
-
Glad you got it figured out!
-
Is that the only system you've tested with? Some repeaters don't encode the PL tone when they transmit the hang time, so you might see the green RX light but the radio will be muted. You should try talking with another radio directly on simplex to see if they are able to work together.

We're working on a new website and this will be one of the first "new" features once it's rolled out. There will be a voting system where people can indicate whether a given repeater is online or not. Using this information, we can get rid of the offline and outdated systems. Right now, we hide anything older than a year from the map page, but that's not perfect. There are systems that haven't been updated in a long time that are still on the air, and some that were listed more recently that are already gone. I think this voting system will be the better way to handle it unless someone has better suggestions. I think requiring someone to log in every year to update the listing is difficult to do, and risks hiding good stuff out there. We could also handle signal reports through this system so you can get feedback on where people are reaching it from and the signal quality.
