Hytera HR652 | Compact Radio Repeater

[Music] this is the haera HR 652 compact radio repeater in this video we're going to be talking about some of the features of the new hia HR 652 repeater as well as some of the different ways you can configure this repeater because there are a number of different ways you can configure it as well as some of the different options that are available for this radio repeater but before we get into that at a very high level I want to explain what a rep radio repeater is for those who might not know so a radio repeater uh very simply put is a piece of radio communications equipment that if configured properly and placed properly can greatly improve the range of your radio Communication System traditionally this is done by receiving signals on one frequency and then retransmitting them on another so you would take this radio repeater and you would put it at a location that's either centrally located or at a high elevation or both to all of your users and create wide area coverage what makes this radio repeater unique is that it is a compact field Deployable radio repeater uh with this radio repeater as we'll talk about you can mount antennas directly to the top of it and there's even a portable battery pack that can be attached to it um to use this thing in in a remote location um whereas a traditional radio repeater like a classic Radio repeater it looks like a computer server and it would be typically mounted in a server rack and then you'd have your antenna running out onto your rooftop or wherever your antenna might be so some of the basic features this is a 25 watt repeater it can do analog mode as well as digital DMR mode um and it can also do analog digital Auto switching analog digital Auto switching is where the repeater can um simultaneously listen for both analog and DMR or digital signals and then transmit either one of those types of signals and it can also do something called sfr or single frequency repeater mode and this is a DMR technology and if you remember as I mentioned a radio repeater traditionally works by receiving on one frequency and transmitting on another because of how mrr Works we're able to split a single frequency into two time slots time slot one and time slot two with a traditional repeater where uh we are receiving on one frequency and transmitting on another with with a sfr single frequency digital repeater we are receiving on one time slot and transmitting on another time slot but on the same frequency and this has some benefits that we'll talk about a little bit later on in the video um so the first thing that you're going to need to consider when deciding how to set up this sfr or sorry this uh HR 652 repeater is how you're going to power it um it comes from the box with the radio repeater and a DC wire harness this is a very basic wire harness it has two bare ends and it attaches from an aviation pin Aviation type pin right on the top of the repeater here just like that so that plugs into the top of the repeater and then with your bare wire ends you'd either run that to a third-party uh power supply like a variable power supply that you might buy on Amazon for like $60 and then just be sure to be feeding it the correct amount of power um or you could run this directly to a battery what you'll notice is this is obviously not a uh a you know you can't plug this into a wall outlet this is not a standard wall plug if if you do want to be able to plug it in directly to a wall hia offers a um a power supply which uses a standard wall plug and allows you to power the repeater directly off the wall as I mentioned this is an optional upgrade um and this is also what you would need if you want to charge the optional battery pack so the optional battery pack I'll show you how that goes on here the optional battery pack connects to the repeater just like that and this mainly has two functions the first function would be providing backup power so if you have kind of a traditional setup you're located in a building or anywhere else where you might be able to have Wall power let's say you've got your um either your power supplies I mentioned with the DC wi wire harness that's included or you have the the wall outlet like this guy right here and you have this thing plugged into the wall um but you want to ensure that in the event of a power outage you're able to maintain Communications with this battery pack in the event that there's a power outage the radio repeater is going to recognize that it's not receiving power um anymore and it's going to switch over to its its battery pack and then the other way that this might be valuable is if you want to do a remote setup so if you want to run this repeater on a Hilltop or on top of a mountain or anywhere else where you might not have um you might not have Wall power even like you know if you're a security company you're doing security at a concert venue uh anything like that this is something that you can do you can use to power the repeater remotely so the next thing that you're going to want to consider is how you're going to set this thing up with an antenna and with this there's a couple options what you have to consider is that uh without getting into too much detail of how how radio repeaters work you need to separate the receive and the transmit side and there's really two ways of doing this and uh and this is done so that you don't damage the radio repeater because what can happen is you can if you're if you're transmitting um let's say with two antennas one for receive one for transmit you can end up pumping all your transmit directly back into the radio repeater and damaging your your repeater so what we need to do is one of two things either have two adequately spaced antennas or use something called a duplexer now as you see you can mount an antenna directly to the top of the repeater just like that and and this is your transmit Port over here and then over here is your receive Port so you might be wondering well can I just run another antenna right here and the answer is it's not recommended we've talked to the high Terra um reps and this is just not nearly enough separation even at a low power output to ensure that you're not going to damage your radio repeater and that's not something that's that's um specific to this repeater that's all repeaters you you need to separate your transmit and you receive so as I mentioned you can do this either by having two antennas that are adequately spaced apart and depending on um how much power you're pushing and how far the separation is between your two frequencies is going to determine how um far apart those antennas can be to provide adequate isolation between the two but traditionally what people do is they use something called a duplexer and a dup duplexer is a piece of RF filtering equipment that you tie both your transmit side and your receive side into it and it provides filtering and then allows you to use a single antenna so that brings us to the next option for this radio repeater higher offers an internal duplexer that can be uh installed inside here and it would be tuned to the specific frequencies that you're going to use your receive uh frequency and your transmit frequency and it's going to go in here and it's going to maintain its small form factor because it's going to be installed directly into the into the repeater now you could go out and buy a mobile duplexer and you'd probably save a little bit of money that way um if you wanted to if you wanted to go that route and use your own duplexer you can do that but you're not going to get the small form factor that you're going to get by using the proprietary duplexer that mounts inside the repeater and then once that duplexer is installed you just use the single transmit port and you can run an antenna just like this um right on the repeater if you want to do it that way if you had this thing mounted in a building and and it's a more traditional type of install you could have your coax cable like this um running up to your rooftop wherever you have your antenna so you can still do that um and then you know as you see you could you know do a do a um a tripod mounted antenna something like this right here this is just a directional antenna on a tripod running their our coax to our repeater um the repeater does not come from high with an antenna however if you buy this from rang Communications we will provide you with a very basic antenna um that can screw onto the top just like this and you know if you do want something like a tripod mounted antenna we do those for people as well so you can reach out to us and we can get you set up with whatever you need now that brings me to another feature that I mentioned earlier which is sfr mode single frequency mode so single frequency mode uh one of the major benefits is that we don't need a duplexer and we don't need two antennas since we're only using a single frequency we don't have a frequency split one for transmit one for receive we're using a single frequency and instead of receiving on one frequency and transmitting on another we're receiving on one time slot of the one DMR time slot and then transmitting on the other DMR time slot so what this allows us to do is just run a single antenna with no duplexer so some of the benefit there is that you are going to get um you know a compact package without having to run a duplex or you're going to cut down on your weight you're going to save some money because you don't need to buy that duplexer uh FCC licensing can also be a little bit easier with sfr because as far as the FCC is concerned it's really a mobile radio um since it's only using a single frequency it's not not really treated as a repeater um some of the considerations with sfr isoss compatibility um this is one thing that you definitely want to consider um unlike traditional analog mode and digital mode which is a standard it's cross- compatible across Brands you could have Motorola equipment you could have uh um High Terra equipment and they can both talk on on a repeater on on standard digital DMR mode um you could even have you know somebody with a bow fying on analog and somebody with a hia not a problem in traditional mode with sfr it's a proprietary um type of technology and so to ensure that it works properly across all um all your radios we recommend sticking to one radio brand so in this case if you have a high teror radio you're doing sfr we recommend just stick with all high teror radios um to ensure that you don't have any cross- compatibility issues um now you might also wonder can I do both and the answer is yes as long as you feel comfortable taking um the duplex FX route so if if you're running a traditional analog or digital or uh mix mode Auto switching repeater and you have your duplexer that's in here and it's tuned to your frequencies um you can still do sfr you need the sfr license on the radio repeater and you could have you know Channel One be your your traditional repeater mode and then uh channel two could be your sfr mode but when you switch to that sfr mode you're going to need to remove that duplexer and um that's not that hard to do there just a couple screws and a couple connection points um so if you're comfortable doing that there's no problem you can run both sfr uh or you can have the option to run either sfr um or um traditional analog digital repeater mode uh if you don't know what you need um you can always reach out to us we are happy to help you we can get this thing set up for you with all of its programming uh we can kind of talk to you figure out what makes the most sense for your scenario um we'll get it programmed we'll get all your handhelds programm we'll send the whole system to you as a configured system ready to go out of the box um all right so I think what we're going to do now is we're going to head out into the field and do a quick demonstration on how this thing works uh we have an sfr license on here right now so we're going to be demonstrating sfr mode but for the purpose of this demonstration um it it it should really kind of just give you a general overview of how recuits work generally so we're going to head out there and and you'll get to see how this thing works selecting a good location is probably the number one factor that's going to impact the amount of range you're going to get with your radio repeater there are a lot of things that can impact the amount of range you're going to see out of a repeater including the power output of the repeater the sensitivity of the receiver and the gain of the antenna that you're using but the number one factor above all else is going to be the placement of the repeater what you want is something that has good line of sight to all your users so something that's either going to be centrally located or something that's going to be at a high elevation or both in this case we're on a Hilltop that has a good 360° field of view in all directions um in this case we are testing the hia HR 652 compact repeater we have it set up with the optional battery pack which allows us to run this thing remotely without any need for uh you know AC wall power um we we have a single frequency license on that that's an optional feature which allows us to use a single antenna and it allows us to do so without needing a duplexer so we're going to go ahead and get this thing set up we're going to go ahead and ratchet strap it to a tree and then we're going to run some tests all right so we've got the repeater ratchet strapped to a tree what we're going to do is we're going to head down the hill get in our cars and we've got somebody on the other side of this terrain and we're going to be talking on our radios in Simplex mode that's radio to radio with that other radio and we're going to keep driving until we lose contact with them which will tell us that the radios are out of range in direct mode at that point we'll switch over to the repeater Channel and if this thing's working properly they should be able to hear us all right so almost immediately after getting off that hill we lost direct communication on our Simplex Channel radio to radio with our other radio so we uh we headed down the hill we lost contact but then we kept driving we actually are all the way in another town now and we're going to go ahead and try on simplex and I doubt we'll be able to hear them uh and then we'll switch over to repeater mode and if everything's working properly they should be able to hear us I have the uh hia HR 782 radio that we're going to be testing with so we'll go ahead and try in direct mode first radio test 1 2 3 4 5 all right so it doesn't look like we're getting anything back on our direct mode we'll go ahead and switch to the repeater Channel they're also monitoring that one for us radio test 1 2 3 4 5 I hear you loud and clear on the repeat tannel great thank you we just tried to call you on Simplex were you able to hear us on that other channel I was not able to hear you on the other channel great thank you so as you'll see running through that repeater that worked out very well uh we were using our sfr channel uh we were actually using AES as well aes256 with multi multi- key encryption um if you guys need any radio communications equipment handhelds or repeaters you know where to find us
