Analog radio is awesome, but digital has it's points. Isaac and David discuss how to program DMR radios and why you might want a business license over an amateur license.
I agree with you on nothing is illegal as long as you pay the fee. I’ve said it a hundred times. SBR’s, SBS’s, full auto and suppressors aren’t illegal as long as you pay the extortion fee to the ATF. If they’re illegal they should be illegal, we shouldn’t have to pay a “tax” to exercise our rights.
FYI: US Army uses HF radios has the E in their PACE plan (Primary, Alternate, Contingency, Emergency) due to the fact that they are highly resistant to jamming and very versatile (Voice and Data) I would love to see TrexArms work through and publish their PACE plan. Show us what right looks like for civilians and establish best practices.
That would be AWESOME, and is much needed for those of us that are serious about establishing solid communications but lack the experience and knowhow.
your comment is exactly why people like you need to have a license to operate. You are talking about a situation where there is a puclib emergency or natural disaster. when you dont need a license. and even so when power is down and the emergency generators have run out of gas on a repeater or cell tower. HF is low frequency and not everyone has an HF radio and HF radios are usually large and heavy
This is perfect. We just had a sever ice storm in Oklahoma that has left 300000 people without power. It’s been a great opportunity to test my teams coms plan.
I love the way you guys produce content. Please keep more videos coming from all ends of the spectrum. From guns to radios to gear and everything else.
Recently picked up the Anytone AT-D878UVii plus and it is by far the best radio I have ever owned. It does DMR very well, does APRS RX and TX for both DMR and Analog, the reach and clarity of dtx and Rx are fantastic, long battery life, and fairly durable. I have come to realize that there is no perfect radio that will do everything you need it to. Where it shines in one important area, it will lack in another. This is the closest I have found to the "perfect" SHTF 2m, 70cm, and DMR HT. It's biggest short coming is that it isn't ipx7 rated. It is IP-54 water and dust resistant, in addition to having a pretty durable case. Just from my personal experience, if anyone is looking for a quality HT that won't break the bank the 878 uvii plus is a fantastic option.
I agree with you on the Anytone. 2nd place for best budget do all SHTF radio right now is the TYT MD-UV390 Plus GPS. 100ish bucks for a dual band, ip67 rated DMR/analog HT that can be firmware-flashed to unlock a bunch of features.. Its got a loud speaker, mic gain adjustment, and a bright screen and feels like a commercial radio (it really is one) Can do digital simplex and can handle 256 AES encryption (as of Sep 2023) as well as digital messaging and GPS coords. There are a lot of quirks with this radio but it is a super solid piece of kit once you flash it to MD380 tools or GD77.
@@krevo81 what kind of quirks? I'm gonna look into it. Currently looking for a good speaker mic for the anytone. Looking at either the powerwerx or the impact platinum series. Want something that can handle the elements but also not suck at it's primary job or randomly just cut out
Quirks such as being a Chinese clone of MotoTRBO (which is already a pain to program via CPS) They are just kinda weird with the standard firmware (no screen dim, volume on low isn't low enough, not superhet like their single band predecessors, etc) Otherwise they are super-rugged from my experience and ip67 rated so I deal with the quirks and flash them over to one of many improved firmwares that open up a lot of features@@collinjones311
After the 2011 9.0 earthquake in Japan, wireless data and voice Internet were down. No GPS navigation with google maps or other online maps either. I had my family, including kids in strollers, and our train in Tokyo stopped running. Navigation, communication and transportation were very difficult. We walked far through throngs of people and traffic was stopped. *Never imagine that google maps is a valid option when navigation is critical.*
The only issue with DMR radios is if someone doesn't want you on their repeater, they can "kill" your radio, making your radio non-functional, forcing you to factory reset it. People have been abusing this feature by setting up public repeaters, then when anyone but their friends use the repeater, they do the "kill" command. D-STAR and Fusion are so much better.
you can shut this feature off in most radios, the proper way is for the repeater owner to just not allow you access. first thing i did when i got my radio was turning off all remote /OTA stuff like that
Just get two radios and and "revive" the dead one with your working one if you can't disable it in the CPS. I don't know how well that works with Motorola's but with the Chinese ones, they don't seem to care which radio the revive command comes from so long as it has the correct radio ID.
@@nicksanjay3902 that would be stupid in a shtf situation. Someone using the repeater isn't harming you or your repeater in anyway. It just allows them to be able to transmit a message. Only reason I could see it being an issue is if someone is they are causing interference to specifically tie up the repeater
@@collinjones311 That is true, but what about a hostige group attempting to use your repeater to relay their own messagers in a SHTF scenario? In that case I would love to SIGINT them first and shut them out of their means of comms second.
When I was in Afghanistan, a lot of the troops used personal GMRS radios to talk to each other on the base. The Taliban was able to listen in and figure out when the radio chatter increased significantly that a VIP was about to visit and they would increase their rocket attacks. The chain of command finally put an end to it.
You do not have to be and expert to know that when radio chatter increased something is going down. I have managed oil rigs all over Asia on multinational projects and I could tell that some shit is going down just by listening to the radio with zero knowledge of the language. Saying on the radio that you have oil spill would get you banned in Russia or Canada since government would listen in on our radios. It is not a spill but loss of primary containment.
friend of mine had a 50ft tower built and used as an antenna that we hooked to a CB And an amp and we chatted to russians mexicans french it was crazy how far away the signal went
I don’t for one moment believe cb is totally dead bcuz as soon as things go sideways tens of thousands of cb and antennas will go right back up that have sat in basements for 20-30 years. That said they suck as hand held radios but any am with side band will be very important
I think you are talking about the store and forward feature with the pd900 series radios. They are developing a tier 3 dmr standard that divides the bandwidth into 3 time slots. Hytera also does ip site connect as well as full on tdma for office settings. You can send texts, email, and even voice to text via the IP connect option. They even offer a phone call to radio connection depending on how much you want to pay. Let's say you have your facility trained to prevent an active shooter, or imminent threat plan and need to quickly and easily sound the alarm, you can text a code to a computer/repeater, and have that trigger all sorts of previously set up actions.
Solid video covering valuable info. If you have your code plug setup. In CPS go to menu and enable fpp. At least on the keypad models like the PD872. You can then edit or change channels from settings in the radio. Good to setup a fpp analog and fpp digital zone. Or you can do it in one. Kind of a game changer for on the fly. Keep up the good work!
Very interesting results. In my time in the Army using Digital and Analog Radio Communications (on the same radio transceiver), we always got farther range with Analog Voice communications, followed by Encrypted Voice, and lastly Digital Data. Makes me think what Hyterra seems to have got right that L3/Harris, etc all haven't been able to.
Been using baofengs for years. Cheap, easy, tough, and effective. We get close to a mile to two miles on a good day. Add some ear peice mikes, some push to talks, and some floppy antenna its pretty good combo!
you should have rob braxman on your show to talk about cyber security free speech and general 1st amendment stuff. big advocate with alot of content and expertise.
For non professional use , the 27 mhz am side provides greater range and ease of use for grid down , apocalypse stuff. Pretty easy to set up home base stations and mobile units , to get 5 , 10 , 15 miles and more . And it doesn't even really work on line of sight. Mobile to mobile not as good , but mobile to base is good. Base to base is maximum range. Lot of white noise junk during the day , but night coms are great.
@@MHLivestreams : …but you don’t have the range of transmission, or reach the 10 meter band does (CB is in that band-and anyone can have a “Children’s Band” radio ;)
Very informative presentation! To the degree that survivable comms are still of interest to you, could I suggest that you make a video about how to hook up Winlink on 20 meters? I think this is the most practical solution for non-local communications in times of distress. It assumes a general amateur radio license which I have but not that hard to pass the test. For what it is worth I have all the equipment including quarter wave dipole antenna just not that easy to put it all together. Thank you.
Always helpful info. Love the comms talks please keep doing them! Very palatable information for the technology challenged basement operators out here!
VHF and UHF can reach quite a long distance with just 5w of power if you have line of sight and a good antenna. Check out a 2m/70cm roll up J pole antenna for field/go-bag use.
i've hacked up a couple of cheap Chinese 70cm - 2m mag mount antennas, made it onto a vertical dipole type of thing, and mounted it on a 20ft tube (insulated from the tubing.) on the chimney, Works great with half inch low loss coaxial cable.
Trying to learn anything about this is daunting to say the least! The only info I could find in my country was, you can import radios unless you get a amateur license in 2015 11 people wrote an exam for a license 4, passed and the "hobby was dying".
Motorola DTR radios are license free UHF radios that do FHSS and have a key for your groups so that they are difficult to monitor. They can be "found" but FHSS makes DF'ing more difficult. Yes you can "see" the conversation with an SDR but doing direction finding is still a bit more difficult. They are Mil-Spec with regard to water, dust and vibration but the case is a plastic body and they have a Moto plug for headsets. What I would love to do is design an aluminum case for the internals and alter the boards to have a NATO connector so you can use higher end PTT devices. I have often thought of reaching out to Motorola to see if they would produce a limited run like that in OD green.
Love my DTR410 for neighbors on Public channels. The family has DTR550’s with private group calls and direct text messaging. The Dads and Tac teams then have full DTR650’s in manager modes and use private, digital frequency hopping spread spectrum. Excellent license free push to talk coms … with repeaters if you wanted. Texting and paging is awesome…
38:07 color code can be used as a pseudo encryption, color code on digital mode makes it harder to listen in to people. I am not an absolute radio expert, just a ham gen class, working on extra, with a krakensdr coming in for radio direction finding. When I get the kraken I can come on some time and teach how to use it for absolute dummies, it is a $400 sdr that autocalibrates and overlays the enemy positions on a map. Dragon OS is also good for things like this which can be ran on a cheap raspi pi computer.
Ever try programming the PF1 or PF2 to allow a promiscuous listening mode on your Anytone I have a Alinco for ham radio use very similar radio and fyi same Color Code is preferred for repeater use what this function does is makes sure that radio ignores DMR frequencies with out the programed code plus gives you a little more range in theory p.s.Love the show
Color code is to dmr what ctcss and DPS codes are to frs but that actually work. Think of it like a way to lock radios to that specific color code and not allowing a 1cc radio Joe blow learning dmr, to transmit to the 4cc repeater that is priority for emergency services.
I love the Hytera radios. I have UHF MD 782, VHF MD 782, UHF PD 782, VHF PD 782. They are front panel programmable. The MD series requires the DTMF mic to FPP. Great radios.
getting my tech license was the easy part, but went for my general but was using an outdated practice test app... failed 3 times and just said, well HF is expensive anyway haha now im more into SDR and trunk decoding for p25 and airband listening since i live near an airport, and yep a spaceforce base, good ol Buckly, they have the massive dome sats for SIGINT like there in Pine Gap you can see them from the rd and google maps if you look around Aurora, I want to get a better SDR so i can see what kind of signals they are using, i know they use like in the GHZ with the MILSAT things, but it be cool to figure out how to use RF to make a radar almost like ADS/b but for ballistic missiles or something you can make a mobile SIGINT / COMINT rig with a dual RTLSDR rig with a tablet and SDRangle its pretty dope
Great video! Great info! David really doesn't like you cutting him off. He is the technical expert so you should defer to him on all the tech talk. The looks he give you when you cut him off make me want to warn you to lock up all the toys that use ammo.
DStar n System Fusion are open if you have a radio that supports it from my understanding. DMR is probably popular since it’s been out longer. But isn’t easy to program. They really are talking about things that they don’t know much about. I’ve seen a guy hit a repeater from a HandHeld talk to someone in Washington State via repeater. echo link or something like that.
To link your repeater to other repeaters to extend your comms over a bigger area, you can use WiFi P2P links or private fiber optic runs, that way your repeaters are linked on a dedicates network and if far more robust as you control it.
So it's like a cooperative of amateur radio hobbyists who maintain repeaters/network that pass signals to cover larger geographic areas? Am I getting that right, on a very basic level?
Licensed HAMs have access to repeaters and depending on what repeaters you are near, you can talk globally. Example is the winsystem www.winsystem.org/
You all are my new favorite video to watch I’m a retired EE and had fires arms over 15 yr ago and got away from it.. recently my brothers and I decided to start training heavy for ...emergencies plus let’s say lol... I have over 40 yr of MMA, as well as owned and operated a MMA SCHOOL FOR 20 years in addition to the EE for the DOD, and I closed the school too focus on family . I have two kids wife granddaughter and a large Italian family of siblings and cousins ,,,LoL. And I get the task of leading teaching and research... and as you can assume I found you on UA-cam.....all that was said so I can just say we love you LOL. We all think everything you do is of the best. Quality of tutelage and format and I am so happy to have you...
I went land mobile in a stealth RV with a 3-inch lift and A/T tires. Installed an Icom 7100 (mobile) and Icom IC-705 (backpack) as well as a smattering of analog and DMR HTs. They literally can't turn off my water or sewer. I go full-bore a-hole if I like and just dump my black tank in a field somewhere in the back-country. I can literally hike in to just about anywhere and transmit both voice and data, to include pictures if needed.
You could always use SOCIETY, which is a decentralized encrypted communication app I’m working on at my company. It runs over your cell but can both tunnel and run peer to peer over your own network. Which means as long as you have local network infrastructure you can communicate.
Timothy has some fantastically high mountains one is called baldy mountain on the border with North Carolina and it's one of the highest peaks in that particular region and there's some other ones around there that are the best famous which a repeater could be placed in the top of a tree.
motorola and Harris are the two big competing factions. Those two usually get the law enforcement, public safety sectors or military sales. There are other smaller brands like Kenwood, ivc, midland etc.
Motorola is the gold standard for commercial radios and Kenwood as well as ICOM. Harris is a pos, nobody at work likes them and had better luck with ge radios
@@mikemcdonald5147 Harris radios did a p25 system for us and it can't handle the radio traffic and went down several times. And after hurricane Irene we had no coms for several hours
GMRS can have removable anttenas. But that is cool if FRS 8-14 went up from 0.5 watt. That's way better and GMRS would be able to have access to those low power frequencies
@1:07:54 No, you can not legally use a UV-5R legally on any of the PRS or business bands. Only radios with a Part 95 grant can be used on FRS/GMRS/MURS regardless if they meet the power and bandwidth requirements. Only radios with a Part 90 grant can be used on business(LMR) frequencies legally and since the UV-5R is front panel programmable and capable of wideband operation it will never get a Part 90 grant.
“Broadcasting” is reserved for licensed mass-media transmissions. I get what you mean, get the word out far and wide-but “Transmit” is more accurate a description
Okay. You can't just install a repeater. Yes you can. Don't. You need a frequency pair. That pair should be approved by the Frequency Coordinator in your area to avoid messing with other repeaters near by. And repeaters can be linked... extending their range remarkably.
@@SteelWolf13 You are surely right - you typically need two radios (one for tx and the other rx for offset), a controller and a duplexer. So yeah, you build a repeater. I was referring to 17:09 when he grabs a Hytera repeater. But my remark was specifically for a normal amateur radio repeater, commonly 2 meter or 70 cm. A frequency coordinator (an designated person) has a listing of repeaters, their range to each other and the frequency pairs (for tx and rx) and also the power out in watts. It's up to them to ensure mathematically (a little RF physics) that the combinations of these parameters work well across a certain territory. Not doing so can cause sporadic emissions and interference. A crossband repeater like you mention, such as the iCom 5100 mobile unit just has about 50 watts I believe. And although it can do some neat stuff, it's not a tower-based repeater at all. You can jury-rig your own crossband repeater with two baofeng 4 watt radios by cross-connecting the audio in/out ports and enabling the vox mode. Kind of a goofy thing to do, but it will work for short range if you want to convert from vhf to uhf or the other way. : ) If you were to install a tower repeater without talking it out with the frequency coordinator you might get into an argument from legitimate repeater stations nearby when they find out. And they will of course. Usually you don't just arbitrarily choose your own frequencies. They are assigned to you through a process. To find your local coordinator's contact information, just ask a nearby HAM radio club and speak to one of the officers.
@@skm9420 So. My comment was for general knowledge and not directed at T.Rex. I'm simply adding to the conversation. Not putting anyone down or making a correction. I could care less if these fellas put up a repeater with totally off the wall configs. But so that other folks interested in the detail I decided to mention it. Nothing beyond and zero emotion on the topic. Cheers.
Motorola radios are absolutely awesome! But as a company their policy and behavior sucks! I have multiple motos and man they are built like tanks and have excellent quality control. The thing to remember is what they said here. They are hard to program and the customer service for individuals sucks.
Hej, thanks a lot for explaining how it works. Any idea, what kind of stationary radio and antenna would I need to use HAM from Europe or US to Australia. Thanks. V.
This will probably get lost in the comments, but I wanted to get your opinion on a g34 length slide on a pf940 cL (19 length grip) with Rmr and Surefire x300 or TLR-1HL as possible do it all build. I’ve been thinking about this for a while, and am a taller guy. Are there any angles I may not possibly be considering?
Let’s say you have a security company or you’re a private investigator, is there a company where you can pay a subscription to and be licensed to dispatch emergency services to your location on a commercial use walkie?
The shooting club, mma gym or even church might be good starting points. Joining an ambulance, rescue, police or firefighter volunteer program might also work.
Instead of the dual band baofengs, I'd hand out GMRS radios with no button programing. We have good repeaters where I live that extend your range by 10X. Or something like a Quensheng programed to GMRS.
If someone is going to spend $1,000 to $2,000 on an AR, or $500/$600 on a handgun, why go so cheap on radios? For the price of a decent red-dot, you can get a reliable mobile radio with cross-band capability. For the price of a weapons light, you can get a quality HT and an upgraded antenna for the price of a magazine. Extra batteries for the price of iron sights. Also, seek out an amateur radio operator for usage tips, or tons of YT videos. Finally, for too many reasons to mention here, I don't rely on DMR radios for emergency purposes. I have several AnyTone 878 DMR radios - great radios! - but I rely on tried and true analog with cross band mobiles for emergency comms when we have snow storms, power outages, cell towers down, etc.
You aren't using any top secret frequencies. We all have the same bands and pot of frequencies to choose from. Business band, MURS, frs, GMRS, ham, etc. The thing that helps us all is the talk groups, color codes, which slot to use, encryption which we can use illegally or legally depending on what band you are on, etc.
Im learning this an am in a society about to take an exam. I hold two passports legally. Im a US / Swiss citizen. Since, the US and Switzerland aren't or dont have big ideological differences...not an issue with the US at the moment. Its an interpretation that changed 35 or 40 years ago. But, I'm having to take a much harder test and you have rights that are profound on the ability to use and have amature radios as long as you dont disturb the other spectrums with RFI or casue other people health or safety issues but even HOA rules are on shaky ground sort of like my dual nationality. My first biss here born in Florida and me born be Eastern Kentucky no less and how I ended up here is a heck of a story but I'm a hillbilly. Then, I spent most of my young life in the Rockies, graduating from a small college in Helena Montana bedore going to law school back in Louisville, KY. I left for Switzerland (married a Swiss woman and had children) at graduation and have seen the whole dang world at this point. You all are right to be concerned as you live in such a "sheltered" environment from all I have seen in my life. "It's a big bad world out there" has a basis in reality more than you would ever know without having lived and seen rhe world for more than one year and in places like Indonesia, India, Nepal, Malaysia, the while Andian mountain chain from the top to the tip of S.America, Philippines, Singapore, Homg Kong, Thailand, Vietnam, Borneo, all of Europe, every single U.S. State, all rhe Canadian Provinces, Polynesian (Cook, Islands, Fiji, Easter Island, Vanuatu), Caribbean so...a lot of places snd those are places I have spent more than two months and up to multiple years (Switzerland since 2000 with two trips back to be a criminal prosecutor in Libby Montana and an Assistant Attorney General in Kentucky). I live within the range of Iskandar missiles from Belarus. That is disturbing. Granted there are enough nuclear fallout shelters here for every citizen and all males save conscientious objectors must serve in the Swiss Army. Some women, more and more are also joining out of a desire to be equals. The objectors must do community service or must serve in the Civil Defense organization. They are "like" unarmed federal agent when serving and ran our vaccine efforts as well as keep peace, maintain infrastructure, and do disaster relief as do our Army who are observers and do not carry arms outside of the country. But, its common for you to see every weekend and innthe the summer, young men carrying thier SIG 550s around to and from service wearing thier uniforms. Living in Bern, the capitol, you see them often. Baring nuclear war, you would be an idiot to try and invade this nightmare of a geographic fortress. Hence the name "Fortress Switzerland" and imahine all these high mountain villages each where all the young men are waiting for you and every picturesque chalet is a snipers den. The land is teraformed from the two WWs and Tank traps are already dug into to the terrain. The cement barriers like the dragons teeth but much bigger and harder to move are still there. The vallies are steep and narrow. A well placed charge would seal off large sections of the country with long hidden tunnels connecting them that only a few know them all. There are whole cities of fully stocked battalion level C2 areas all over the place and austere operations are already built into the road infrastructure. You can see barriers that can be put in place and then the road is a is a is a runway.
hah, way to thread the legal needle. Yeah, you CAN hit those freq bands and under the legal power rating, programmable, but it isn't 'type approved' so bad dog, no biscuit. But it will totally work. And btw in an actual disaster / emergency the ham transmit license rules don't apply. Question is who defines the emergency.
100% accurate. But anyone who has ever listened to 80m can tell you that FCC rules are rarely enforced, and 5 watt HTs are nowhere on FCCs radar. Literally almost zero enforcement. I don't encourage people to break the law, but the FCC ain't coming for the baofeng commandos.
The Xiegu G90 is 20w, not 10watt as stated. The radio includes an antenna tuner. As for "gigantic" antennas, I use a 4.5 feet home made Magnetic loop and it allows me to talk half the world. You will not find a better radio as this price.
It seems to be solid. I have yet to find a radio that is the perfect radio. Trying to find something that is durable, long battery life, versatile, and has a quality tx and Rx is near impossible. You will generally find a couple of those specs but missing something else that is important. The closer you get to finding all of them, the more expensive it gets and they still have random issues, just a bit more few and far between. I just picked up the d878 uvii plus and seems like it will be solid. Ip54 so not crazy, but got a case and better than no up rating, long battery life,and from what I hear sounds great on tx and Rx. That will be my main radio with a baofeng and maybe an hf radio or 2nd baofeng.
I need clear Radio communication with a maximum clear talk range out to about 8-10 miles... what's the best set up for that ?? I need it for within City use as well as a outdoor Woods /field use.. and indoor outdoor etc.. Best case scenario for that can u offer a decent Kit?
I have a 10 watt handy talkie and I can talk to friends 10 miles out with no repeater. I would not use commercial radios because they are not very powerful and don’t have a lot of reach. If you’re using DMR you’re registering it first with the FCC and if SHTF then the FCC knows where to go to confiscate radios. Only buy Analog not DMR. Also if power goes out the features and advantages that DMR has over Analog goes out the window.
When using simplex the timeslot doesn't matter. You can program TS1 on one radio and TS2 on the other, and as long as they have the correct frequency and talkgroup they will talk. Timeslots are only relevant when using a repeater. Pseudotrunk is a function of the subscriber, NOT the repeater. You can use pseudotrunk Hytera radios on a Motorola repeater.
All pretty basic stuff.... what repeaters work with DMR MotoTurbo2 AES-256 encryption? Only ones i can find are Motorolla which are a gigantic PITA to program and are extremely expensive, or BridgeComm Systems. Any other suggestions?
How about SAMCOM 5 watt 2-way Ham Radio? It’s sold on Amazon as “out of the box pre-programmed”. You can download their software and program them but don’t have to if you don’t want to customize
I would check out Ham Radio Crash Course or Ham Radio 2.0 for that answer. Not sure if you're a HAM or not but they are both great resources for information beyond T.Rex Arms basic videos.
I agree with you on nothing is illegal as long as you pay the fee. I’ve said it a hundred times. SBR’s, SBS’s, full auto and suppressors aren’t illegal as long as you pay the extortion fee to the ATF. If they’re illegal they should be illegal, we shouldn’t have to pay a “tax” to exercise our rights.

Recently picked up the Anytone AT-D878UVii plus and it is by far the best radio I have ever owned. It does DMR very well, does APRS RX and TX for both DMR and Analog, the reach and clarity of dtx and Rx are fantastic, long battery life, and fairly durable.
I have come to realize that there is no perfect radio that will do everything you need it to. Where it shines in one important area, it will lack in another. This is the closest I have found to the "perfect" SHTF 2m, 70cm, and DMR HT. It's biggest short coming is that it isn't ipx7 rated. It is IP-54 water and dust resistant, in addition to having a pretty durable case.
Just from my personal experience, if anyone is looking for a quality HT that won't break the bank the 878 uvii plus is a fantastic option.
Absolutely love mine. It's my primary (and favorite) HT and all the 'Fengs have been collecting dust for a while.
I agree with you on the Anytone. 2nd place for best budget do all SHTF radio right now is the TYT MD-UV390 Plus GPS. 100ish bucks for a dual band, ip67 rated DMR/analog HT that can be firmware-flashed to unlock a bunch of features.. Its got a loud speaker, mic gain adjustment, and a bright screen and feels like a commercial radio (it really is one) Can do digital simplex and can handle 256 AES encryption (as of Sep 2023) as well as digital messaging and GPS coords. There are a lot of quirks with this radio but it is a super solid piece of kit once you flash it to MD380 tools or GD77.
@@krevo81 what kind of quirks? I'm gonna look into it. Currently looking for a good speaker mic for the anytone. Looking at either the powerwerx or the impact platinum series. Want something that can handle the elements but also not suck at it's primary job or randomly just cut out
Quirks such as being a Chinese clone of MotoTRBO (which is already a pain to program via CPS) They are just kinda weird with the standard firmware (no screen dim, volume on low isn't low enough, not superhet like their single band predecessors, etc) Otherwise they are super-rugged from my experience and ip67 rated so I deal with the quirks and flash them over to one of many improved firmwares that open up a lot of features@@collinjones311
After the 2011 9.0 earthquake in Japan, wireless data and voice Internet were down. No GPS navigation with google maps or other online maps either. I had my family, including kids in strollers, and our train in Tokyo stopped running. Navigation, communication and transportation were very difficult. We walked far through throngs of people and traffic was stopped. *Never imagine that google maps is a valid option when navigation is critical.*
There's offline maps tho
I love comms videos from trex!!
The only issue with DMR radios is if someone doesn't want you on their repeater, they can "kill" your radio, making your radio non-functional, forcing you to factory reset it. People have been abusing this feature by setting up public repeaters, then when anyone but their friends use the repeater, they do the "kill" command. D-STAR and Fusion are so much better.
I would want that in a SHTF scenario, if i owned the repeater at least...
you can shut this feature off in most radios, the proper way is for the repeater owner to just not allow you access. first thing i did when i got my radio was turning off all remote /OTA stuff like that
Just get two radios and and "revive" the dead one with your working one if you can't disable it in the CPS. I don't know how well that works with Motorola's but with the Chinese ones, they don't seem to care which radio the revive command comes from so long as it has the correct radio ID.
@@nicksanjay3902 that would be stupid in a shtf situation. Someone using the repeater isn't harming you or your repeater in anyway. It just allows them to be able to transmit a message. Only reason I could see it being an issue is if someone is they are causing interference to specifically tie up the repeater
@@collinjones311 That is true, but what about a hostige group attempting to use your repeater to relay their own messagers in a SHTF scenario? In that case I would love to SIGINT them first and shut them out of their means of comms second.
Thank you for all that you guys do. Keep informing the masses.
When I was in Afghanistan, a lot of the troops used personal GMRS radios to talk to each other on the base. The Taliban was able to listen in and figure out when the radio chatter increased significantly that a VIP was about to visit and they would increase their rocket attacks. The chain of command finally put an end to it.
You do not have to be and expert to know that when radio chatter increased something is going down. I have managed oil rigs all over Asia on multinational projects and I could tell that some shit is going down just by listening to the radio with zero knowledge of the language.
Saying on the radio that you have oil spill would get you banned in Russia or Canada since government would listen in on our radios. It is not a spill but loss of primary containment.
People should be publicly flogged for breaches like that.
This is my new favorite Live intro.
Yes
'UA-cam is having problems'
'Bla bla bla censorship bla bla'
And we're live! Haha it was a good moment
friend of mine had a 50ft tower built and used as an antenna that we hooked to a CB And an amp and we chatted to russians mexicans french it was crazy how far away the signal went
Yeah it’s awesome I used to talk skip all the time
I don’t for one moment believe cb is totally dead bcuz as soon as things go sideways tens of thousands of cb and antennas will go right back up that have sat in basements for 20-30 years. That said they suck as hand held radios but any am with side band will be very important
@@Burns14223375 Yes, I totally agree
I think you are talking about the store and forward feature with the pd900 series radios. They are developing a tier 3 dmr standard that divides the bandwidth into 3 time slots. Hytera also does ip site connect as well as full on tdma for office settings. You can send texts, email, and even voice to text via the IP connect option. They even offer a phone call to radio connection depending on how much you want to pay.
Let's say you have your facility trained to prevent an active shooter, or imminent threat plan and need to quickly and easily sound the alarm, you can text a code to a computer/repeater, and have that trigger all sorts of previously set up actions.
Radio is wonderful isn't it
Solid video covering valuable info. If you have your code plug setup. In CPS go to menu and enable fpp. At least on the keypad models like the PD872. You can then edit or change channels from settings in the radio. Good to setup a fpp analog and fpp digital zone. Or you can do it in one. Kind of a game changer for on the fly. Keep up the good work!
Very interesting results. In my time in the Army using Digital and Analog Radio Communications (on the same radio transceiver), we always got farther range with Analog Voice communications, followed by Encrypted Voice, and lastly Digital Data. Makes me think what Hyterra seems to have got right that L3/Harris, etc all haven't been able to.
Freq. Usage. Power. Location
Those were always already taken into account, as well as retransmit sites in support.
Been using baofengs for years.
Cheap, easy, tough, and effective.
We get close to a mile to two miles on a good day.
Add some ear peice mikes, some push to talks, and some floppy antenna its pretty good combo!
Whats a good cheap floppy antenna?
What are your thoughts on the walkers razor walkie talkie attachment since the baofengs are also roughly the same range?
you should have rob braxman on your show to talk about cyber security free speech and general 1st amendment stuff. big advocate with alot of content and expertise.
Use this
For non professional use , the 27 mhz am side provides greater range and ease of use for grid down , apocalypse stuff.
Pretty easy to set up home base stations and mobile units , to get 5 , 10 , 15 miles and more . And it doesn't even really work on line of sight.
Mobile to mobile not as good , but mobile to base is good. Base to base is maximum range.
Lot of white noise junk during the day , but night coms are great.
digital channels are totally quiet and 'secret' - no unwanted visitors on your channels of choice
@@MHLivestreams : …but you don’t have the range of transmission, or reach the 10 meter band does (CB is in that band-and anyone can have a “Children’s Band” radio ;)
We have GMRS repeaters in north Phoenix that cover 100 miles. Two major networks are now linked multistate. Times have changed.
Very informative presentation! To the degree that survivable comms are still of interest to you, could I suggest that you make a video about how to hook up Winlink on 20 meters? I think this is the most practical solution for non-local communications in times of distress. It assumes a general amateur radio license which I have but not that hard to pass the test. For what it is worth I have all the equipment including quarter wave dipole antenna just not that easy to put it all together. Thank you.
3:20 that Phantom Menace reference went way over their heads lmao
Always helpful info. Love the comms talks please keep doing them! Very palatable information for the technology challenged basement operators out here!
VHF and UHF can reach quite a long distance with just 5w of power if you have line of sight and a good antenna. Check out a 2m/70cm roll up J pole antenna for field/go-bag use.
i've hacked up a couple of cheap Chinese 70cm - 2m mag mount antennas, made it onto a vertical dipole type of thing, and mounted it on a 20ft tube (insulated from the tubing.) on the chimney, Works great with half inch low loss coaxial cable.
Trying to learn anything about this is daunting to say the least! The only info I could find in my country was, you can import radios unless you get a amateur license in 2015 11 people wrote an exam for a license 4, passed and the "hobby was dying".
Motorola DTR radios are license free UHF radios that do FHSS and have a key for your groups so that they are difficult to monitor. They can be "found" but FHSS makes DF'ing more difficult. Yes you can "see" the conversation with an SDR but doing direction finding is still a bit more difficult. They are Mil-Spec with regard to water, dust and vibration but the case is a plastic body and they have a Moto plug for headsets. What I would love to do is design an aluminum case for the internals and alter the boards to have a NATO connector so you can use higher end PTT devices. I have often thought of reaching out to Motorola to see if they would produce a limited run like that in OD green.
Love my DTR410 for neighbors on Public channels. The family has DTR550’s with private group calls and direct text messaging. The Dads and Tac teams then have full DTR650’s in manager modes and use private, digital frequency hopping spread spectrum.
Excellent license free push to talk coms … with repeaters if you wanted. Texting and paging is awesome…
It's amazing to me that there seems to be very little HAM / Tactical community cross over.
Please look into boosting the audio. Thanks.👂👍
I love ❤️ Your stuff…. I stand United with You in Your views and fight with You… back to back against tyranny 🇺🇸
38:07 color code can be used as a pseudo encryption, color code on digital mode makes it harder to listen in to people. I am not an absolute radio expert, just a ham gen class, working on extra, with a krakensdr coming in for radio direction finding. When I get the kraken I can come on some time and teach how to use it for absolute dummies, it is a $400 sdr that autocalibrates and overlays the enemy positions on a map. Dragon OS is also good for things like this which can be ran on a cheap raspi pi computer.
Ever try programming the PF1 or PF2 to allow a promiscuous listening mode on your Anytone I have a Alinco for ham radio use very similar radio and fyi same Color Code is preferred for repeater use what this function does is makes sure that radio ignores DMR frequencies with out the programed code plus gives you a little more range in theory p.s.Love the show
Color code is to dmr what ctcss and DPS codes are to frs but that actually work.
Think of it like a way to lock radios to that specific color code and not allowing a 1cc radio Joe blow learning dmr, to transmit to the 4cc repeater that is priority for emergency services.
you mean the state gets the priority.
I love the Hytera radios. I have UHF MD 782, VHF MD 782, UHF PD 782, VHF PD 782. They are front panel programmable. The MD series requires the DTMF mic to FPP. Great radios.
What’s the range on the pd782 ?
getting my tech license was the easy part, but went for my general but was using an outdated practice test app... failed 3 times and just said, well HF is expensive anyway haha now im more into SDR and trunk decoding for p25 and airband listening since i live near an airport, and yep a spaceforce base, good ol Buckly, they have the massive dome sats for SIGINT like there in Pine Gap you can see them from the rd and google maps if you look around Aurora, I want to get a better SDR so i can see what kind of signals they are using, i know they use like in the GHZ with the MILSAT things, but it be cool to figure out how to use RF to make a radar almost like ADS/b but for ballistic missiles or something
you can make a mobile SIGINT / COMINT rig with a dual RTLSDR rig with a tablet and SDRangle its pretty dope
You should sell radios online and offer local programming
Great video!
Great info!
David really doesn't like you cutting him off. He is the technical expert so you should defer to him on all the tech talk.
The looks he give you when you cut him off make me want to warn you to lock up all the toys that use ammo.
Hi Guys - appreciate the videos and insights. Question: why did you choose DMR over DStar?
DStar n System Fusion are open if you have a radio that supports it from my understanding. DMR is probably popular since it’s been out longer. But isn’t easy to program.
They really are talking about things that they don’t know much about. I’ve seen a guy hit a repeater from a HandHeld talk to someone in Washington State via repeater. echo link or something like that.
DMR is the worst of the digital modes honestly.
You guys have said SOOOO much in your introduction about our three or four letter agencies, who really are affective, should be abolished.
To link your repeater to other repeaters to extend your comms over a bigger area, you can use WiFi P2P links or private fiber optic runs, that way your repeaters are linked on a dedicates network and if far more robust as you control it.
Doesn't that make you dependant on other tech?
@@walterp380 Yes on network equipment, but not on other people's network / Internet. If you set it up properly the first time, it will last
So it's like a cooperative of amateur radio hobbyists who maintain repeaters/network that pass signals to cover larger geographic areas? Am I getting that right, on a very basic level?
I watched a demo of bao feng where the guy talked coast to coast using repeaters. He was licensed to have access to repeaters
Licensed HAMs have access to repeaters and depending on what repeaters you are near, you can talk globally. Example is the winsystem www.winsystem.org/

I went land mobile in a stealth RV with a 3-inch lift and A/T tires. Installed an Icom 7100 (mobile) and Icom IC-705 (backpack) as well as a smattering of analog and DMR HTs.
They literally can't turn off my water or sewer. I go full-bore a-hole if I like and just dump my black tank in a field somewhere in the back-country.
I can literally hike in to just about anywhere and transmit both voice and data, to include pictures if needed.
You could always use SOCIETY, which is a decentralized encrypted communication app I’m working on at my company. It runs over your cell but can both tunnel and run peer to peer over your own network. Which means as long as you have local network infrastructure you can communicate.
Timothy has some fantastically high mountains one is called baldy mountain on the border with North Carolina and it's one of the highest peaks in that particular region and there's some other ones around there that are the best famous which a repeater could be placed in the top of a tree.

You only need a duplexer if you run one antenna for TX and RX. Two antennas can be used. It's a cost and space consideration.

motorola and Harris are the two big competing factions. Those two usually get the law enforcement, public safety sectors or military sales. There are other smaller brands like Kenwood, ivc, midland etc.
Motorola is the gold standard for commercial radios and Kenwood as well as ICOM. Harris is a pos, nobody at work likes them and had better luck with ge radios

God bless you all. Thanks for the info!
GMRS can have removable anttenas. But that is cool if FRS 8-14 went up from 0.5 watt. That's way better and GMRS would be able to have access to those low power frequencies
I love it. You Botkins look all alike just like me and my brothers!
@1:07:54 No, you can not legally use a UV-5R legally on any of the PRS or business bands. Only radios with a Part 95 grant can be used on FRS/GMRS/MURS regardless if they meet the power and bandwidth requirements. Only radios with a Part 90 grant can be used on business(LMR) frequencies legally and since the UV-5R is front panel programmable and capable of wideband operation it will never get a Part 90 grant.
Thanks for the info! Can anyone recommend any other resources? Books or classes to learn more? Thanks
“Broadcasting” is reserved for licensed mass-media transmissions. I get what you mean, get the word out far and wide-but “Transmit” is more accurate a description
Okay. You can't just install a repeater. Yes you can. Don't. You need a frequency pair. That pair should be approved by the Frequency Coordinator in your area to avoid messing with other repeaters near by. And repeaters can be linked... extending their range remarkably.
I've yet to find a "repeater in a box" solution. I don't consider an Crossband radio a repeater.
@@SteelWolf13 You are surely right - you typically need two radios (one for tx and the other rx for offset), a controller and a duplexer. So yeah, you build a repeater. I was referring to 17:09 when he grabs a Hytera repeater. But my remark was specifically for a normal amateur radio repeater, commonly 2 meter or 70 cm. A frequency coordinator (an designated person) has a listing of repeaters, their range to each other and the frequency pairs (for tx and rx) and also the power out in watts. It's up to them to ensure mathematically (a little RF physics) that the combinations of these parameters work well across a certain territory. Not doing so can cause sporadic emissions and interference.
A crossband repeater like you mention, such as the iCom 5100 mobile unit just has about 50 watts I believe. And although it can do some neat stuff, it's not a tower-based repeater at all. You can jury-rig your own crossband repeater with two baofeng 4 watt radios by cross-connecting the audio in/out ports and enabling the vox mode. Kind of a goofy thing to do, but it will work for short range if you want to convert from vhf to uhf or the other way. : )
If you were to install a tower repeater without talking it out with the frequency coordinator you might get into an argument from legitimate repeater stations nearby when they find out. And they will of course. Usually you don't just arbitrarily choose your own frequencies. They are assigned to you through a process. To find your local coordinator's contact information, just ask a nearby HAM radio club and speak to one of the officers.
They don't have to mention that, they should've, but they have their own req so it doesn't matter.
@@skm9420 So. My comment was for general knowledge and not directed at T.Rex. I'm simply adding to the conversation. Not putting anyone down or making a correction. I could care less if these fellas put up a repeater with totally off the wall configs. But so that other folks interested in the detail I decided to mention it. Nothing beyond and zero emotion on the topic. Cheers.
Motorola radios are absolutely awesome! But as a company their policy and behavior sucks! I have multiple motos and man they are built like tanks and have excellent quality control. The thing to remember is what they said here. They are hard to program and the customer service for individuals sucks.
Thanks for that beofeng go over.. had that thing for years and never figured it out.
Hej, thanks a lot for explaining how it works. Any idea, what kind of stationary radio and antenna would I need to use HAM from Europe or US to Australia. Thanks. V.
Not sure what antennas your using but Nagoya or Diamond antennas would give you more range.
I truly appreciate this...very helpful & how to use...all the options available is truly good
This will probably get lost in the comments, but I wanted to get your opinion on a g34 length slide on a pf940 cL (19 length grip) with Rmr and Surefire x300 or TLR-1HL as possible do it all build.

@@wolfza2630 i think you missed the joke...
Your flannel game is strong.
Instead of the dual band baofengs, I'd hand out GMRS radios with no button programing. We have good repeaters where I live that extend your range by 10X. Or something like a Quensheng programed to GMRS.
Learn about how to use directional antennas. There are many advantages more valuable than having the latest tech.
Good shit. Try and set up a repeater in every squad members vehicle its definite worth it!
If someone is going to spend $1,000 to $2,000 on an AR, or $500/$600 on a handgun, why go so cheap on radios? For the price of a decent red-dot, you can get a reliable mobile radio with cross-band capability. For the price of a weapons light, you can get a quality HT and an upgraded antenna for the price of a magazine. Extra batteries for the price of iron sights. Also, seek out an amateur radio operator for usage tips, or tons of YT videos. Finally, for too many reasons to mention here, I don't rely on DMR radios for emergency purposes. I have several AnyTone 878 DMR radios - great radios! - but I rely on tried and true analog with cross band mobiles for emergency comms when we have snow storms, power outages, cell towers down, etc.
It appears that Kemp has increased their prices significantly. Do you have any other suggestions?
You aren't using any top secret frequencies. We all have the same bands and pot of frequencies to choose from. Business band, MURS, frs, GMRS, ham, etc. The thing that helps us all is the talk groups, color codes, which slot to use, encryption which we can use illegally or legally depending on what band you are on, etc.
Im learning this an am in a society about to take an exam. I hold two passports legally. Im a US / Swiss citizen. Since, the US and Switzerland aren't or dont have big ideological differences...not an issue with the US at the moment. Its an interpretation that changed 35 or 40 years ago. But, I'm having to take a much harder test and you have rights that are profound on the ability to use and have amature radios as long as you dont disturb the other spectrums with RFI or casue other people health or safety issues but even HOA rules are on shaky ground sort of like my dual nationality. My first biss here born in Florida and me born be Eastern Kentucky no less and how I ended up here is a heck of a story but I'm a hillbilly. Then, I spent most of my young life in the Rockies, graduating from a small college in Helena Montana bedore going to law school back in Louisville, KY. I left for Switzerland (married a Swiss woman and had children) at graduation and have seen the whole dang world at this point. You all are right to be concerned as you live in such a "sheltered" environment from all I have seen in my life. "It's a big bad world out there" has a basis in reality more than you would ever know without having lived and seen rhe world for more than one year and in places like Indonesia, India, Nepal, Malaysia, the while Andian mountain chain from the top to the tip of S.America, Philippines, Singapore, Homg Kong, Thailand, Vietnam, Borneo, all of Europe, every single U.S. State, all rhe Canadian Provinces, Polynesian (Cook, Islands, Fiji, Easter Island, Vanuatu), Caribbean so...a lot of places snd those are places I have spent more than two months and up to multiple years (Switzerland since 2000 with two trips back to be a criminal prosecutor in Libby Montana and an Assistant Attorney General in Kentucky). I live within the range of Iskandar missiles from Belarus. That is disturbing. Granted there are enough nuclear fallout shelters here for every citizen and all males save conscientious objectors must serve in the Swiss Army. Some women, more and more are also joining out of a desire to be equals. The objectors must do community service or must serve in the Civil Defense organization. They are "like" unarmed federal agent when serving and ran our vaccine efforts as well as keep peace, maintain infrastructure, and do disaster relief as do our Army who are observers and do not carry arms outside of the country. But, its common for you to see every weekend and innthe the summer, young men carrying thier SIG 550s around to and from service wearing thier uniforms. Living in Bern, the capitol, you see them often. Baring nuclear war, you would be an idiot to try and invade this nightmare of a geographic fortress. Hence the name "Fortress Switzerland" and imahine all these high mountain villages each where all the young men are waiting for you and every picturesque chalet is a snipers den. The land is teraformed from the two WWs and Tank traps are already dug into to the terrain. The cement barriers like the dragons teeth but much bigger and harder to move are still there. The vallies are steep and narrow. A well placed charge would seal off large sections of the country with long hidden tunnels connecting them that only a few know them all. There are whole cities of fully stocked battalion level C2 areas all over the place and austere operations are already built into the road infrastructure. You can see barriers that can be put in place and then the road is a is a is a runway.
Do you have a recommendation for a Non-Chinese radio like the Baofeng?
You guys are awesome,!!!
hah, way to thread the legal needle. Yeah, you CAN hit those freq bands and under the legal power rating, programmable, but it isn't 'type approved' so bad dog, no biscuit. But it will totally work. And btw in an actual disaster / emergency the ham transmit license rules don't apply. Question is who defines the emergency.
The FCC defines it.
100% accurate. But anyone who has ever listened to 80m can tell you that FCC rules are rarely enforced, and 5 watt HTs are nowhere on FCCs radar. Literally almost zero enforcement. I don't encourage people to break the law, but the FCC ain't coming for the baofeng commandos.
The Xiegu G90 is 20w, not 10watt as stated. The radio includes an antenna tuner. As for "gigantic" antennas, I use a 4.5 feet home made Magnetic loop and it allows me to talk half the world. You will not find a better radio as this price.

What's your opinion of the AnyTone AT-D878UV PLUS for SHTF / WROL use? Thanx and stay Frosty! ^v^
It seems to be solid. I have yet to find a radio that is the perfect radio. Trying to find something that is durable, long battery life, versatile, and has a quality tx and Rx is near impossible. You will generally find a couple of those specs but missing something else that is important. The closer you get to finding all of them, the more expensive it gets and they still have random issues, just a bit more few and far between.
I just picked up the d878 uvii plus and seems like it will be solid. Ip54 so not crazy, but got a case and better than no up rating, long battery life,and from what I hear sounds great on tx and Rx. That will be my main radio with a baofeng and maybe an hf radio or 2nd baofeng.

Best case scenario for that can u offer a decent Kit?
8-10 miles will require a repeater for city use. You will need either a GMRS or ham radio license for this.

ComSat1 failed in what, '98? Fubar'd some local comms...had hams in ambulances for dispatch for a bit...😮
So, for programming the Hiteras, I presume you install the program on your Mac/pc before plugging in the radio; is that correct ?
I have a 10 watt handy talkie and I can talk to friends 10 miles out with no repeater. I would not use commercial radios because they are not very powerful and don’t have a lot of reach. If you’re using DMR you’re registering it first with the FCC and if SHTF then the FCC knows where to go to confiscate radios. Only buy Analog not DMR. Also if power goes out the features and advantages that DMR has over Analog goes out the window.

This was a great presentation with some valuable information. Thanks for the hard work!
When using simplex the timeslot doesn't matter. You can program TS1 on one radio and TS2 on the other, and as long as they have the correct frequency and talkgroup they will talk. Timeslots are only relevant when using a repeater. Pseudotrunk is a function of the subscriber, NOT the repeater. You can use pseudotrunk Hytera radios on a Motorola repeater.
