*PLEASE!!! For the love of God and all that is good and holy in this world! Don’t stop making these videos!*
$275 wow. Great job on the build. Definitely a great line for those who don’t understand repeater builds. There are better solutions but you make it easy for those who aren’t techy and don’t want to research cheaper alternatives. Great job
Yeah man I’m not intentionally targeting folks who don’t understand repeaters/builds. Ask anyone - I willingly and gladly give anyone who asks advice on their own projects. $275 is well worth the price for a professional and well built product plus the support I put behind it - especially for those who would prefer not to spend hours building one themselves
Impressive unit
Can you share the options that you mention, if you don't mind.
Can you share the options that you are talking about, if you don't mind.
275 would be a good price point with a solar panel. They're cheap to add to your product, and look cool.
You could even list testing lengths of time.
Great Vid.
Thx and God Bless.
Extremely underrated channel. Great info and cinematography
Thank you! I appreciate that
So glad you guys did this video!! Been waiting for so long and can't wait to use this info to help me further my training and use of the LunchBox!! I purchased mine a while back and haven't used it as intended in fear of not using it correctly and so on... Thanks again for making this and looking forward to more videos and cool items you guys put out!!
Really glad this will help you out!
Love to see it, always coming out with good content!
Thank you!
Great video! I use the radios I've bought from Mojave daily and they always take the time to answer my questions.
Thanks for your continued support Steven!
I'm at the very start of learning about radios. Your videos have been great
Thank you!
Amazing amount of knowledge.
Glad to have stumbled across your channel. I’ve really been investing in upping my field comms knowledge and capabilities this year.
I’m in the midst of building my own simplex/duplex repeater lunchbox, but your training offerings seem like exactly what I’m looking for.
Awesome! Good luck with the build!
Cool repeater build, loved the scenic shots of the old deuce nasty too!
glad i found your channel great content !
I use a setup like your lunchbox for testing coverage for HT users, and for potential repeater sites. Mine is built in a .30 cal ammo can, and has an NMO connector. I also use a NMO to SO-239 adapter for external antenna use. I have a small 12v battery and "battery eliminator" for powering the radio.
Just came across your channel. Great stuff! You are giving out solid info and offering great comm packages to fit a gap in my PACE plan ! Enjoy “Stumps”! 🇺🇸
Sick video 🙌🏼 going to try and catch that Michigan class! Appreciate the knowledge!
Thank you and I hope to see you there!
Just what I was looking for
You guys should look into 3D printing a bracket to use vs a ranger band. Pretty low cost once you get a good design.
Zip tie works well.
Thats kinda one of those things that you do if you already have a 3D printer and know how to play with it. For most people, if it works, it works.
Another option would be to find a small block of FIRM Closed Cell Foam, place a small section of velcro on one side with the other attaching portion on the inside of the case, then wedge the block in place to keep the pinned plug from wiggling free. Leave the Ranger Band on as well as added insurance and the wedged foam should keep it in place, too.
My last question has to do with extending the range of the Baofeng radios by "Daisy Chaining" multiple repeaters along a desired path.
By this I mean can you place two (2) or more say 8-10 km apart from each Mohave device and end up with them literally repeating your transmitted signal?
And would you hear multiple responses back with the senders voice and have to literally COUNT the "echo's" so you'd know when the furthest repeater would have triggered to make sure the message arrived X km away?
Obviously, a LARGER repeater with significantly more power would be the answer but it would be anywhere NEAR as portable in the field.
TIA for any answers you can provide me, assuming you even get to read this since the OP has been up over a year.
Take care and I've now subscribed.
People with 3d printers overcomplicate everything so they can use their 3d printers. It's better he doesn't.
If you notice that band is holding the connection into the speaker/mic port on the side which on these uv-5r's is flawed and has to be held in with "something", likely the reason for the band.
This is cool. Thanks!
What about a solar panel set up to keep up the charge and be able to put it in the field and leave it for months at a time? Is this possible?
Sure. Easy to spot though and an enemy could sabotage it and setup an ambush for you. But do it right, sure. Why not. Also, you’ll still want a battery attached.
Awesome video! Would love to see more about your RTO class (and of course, come to PA/NJ!)
I’m originally from NJ
Definitely need an NJ RTO course.
Good video!
USB charging ports are a cool feature!
This is way cool. I’m subbin!
I did a similar repeater build but mine used two Baofeng UV5R's and I put them in a $19 harbor freight knock off pelican case
How does that work? I am planning to build one.
@@ch0lito I mean it works but it's not the 50 mile range shtf comms system I was hoping for
@@PracticalTacticalSheepDog Oh ok, thanks for sharing, but i think that is better than nothing.
Doesn't work if it's rx and TX simultaneously.... the rx will be overwhelmed by the close TX.
good job!
Top tier info
Thank you 🙏
Could you use a UV-9g for the better mike connection and slightly better battery life?
Good Video. Good explanation. But what if I want one that works on GMRS? Having multiple Lunchbox's? What else do you need to complete this build? What circuit board are you talking about?
You can do encode ctcss on repeater tx, decode on mobile units rx. The mobiles will ignore direct, ctcss'less weak radio tx, but let in repeater signal. No more echo.
Another great solution!
@@MojaveRepeater Thanks! It will not handle much traffic. Quick info/permission coms, no roundtables.
@@whoaedgy7345 Totally agreed
Great video Alex! Great content always!
Thanks man!
Nice repeater
I think you guys should do a video on some of your favorite radios and why
Agreed!
What antenna/waterproof attachment was used to route the antenna out of the box?
How has the 8 watt heat dissipated? How long is the message length? Nice looking package.
Greetings from, Nevada.
How did you mount the antenna connection through the box?
Hi. What antenna do you use, it looks very flexible !!
weird question could i have a analog radio on one side and a dmr radio on the other to make a analog to dmr repeater or vice versa?
Can you add the boxes to repeat repeat over a mou
With the lunch box is it possible to remove the standard radio and install a DMR radio in the same system?
This is awesome content maybe if you can dive into more of the duty style radios and the options available. Thank you.
I definitely plan to do this. Thanks for your comment!
Can I set up the repeater radios to daisychain from one repeater to the next to the next and reverse it?
How do I buy one, I couldn't see it on your site
Great explanation and demonstration thanks for sharing
If i want to use this to repeat encrypted transmission using AES256, will it repeat a clear transmission to my other encrypted radios or it will be blurred no matter what?
You can be the garand thumb of radio. genius.
Haha thanks 🙏
Need yall to do a class in the southeast somewhere. The Sawmill complex would be amazing...
I know this is an older video. Are you folks going to offer this again? I saw it was sold out on your store!
Regards from South Central Indiana. USA
Tim
I’m interested in your lunch box repeater for my family. How much and where do I get one?
When are you going to be back in stock with them
Where can I purchase one of these ?
I think this is what I’m looking for to do a long rage net for our group so my question is could u use more then one of these in a single transmission ie transmit radio to repeater that then sends it to next repeater that then ends at the receive radio? If so I would be very interested in putting them on solar battery banks for a full time all the time net…your thoughts thank you
DITTO! I'm only about 5+ months behind you in finding this page and asking the same basic question about Daisy Chaining several of these units to extend the transmission and reception distances.
Did you ever get a response, and if so, what was the gist of the answer if you don't mind me asking?
TIA, Pardner.
More content on individual setups, ear pro to radio with PTT on a plate carrier and chest rig
Stay tuned. This is coming
How much would one cost being shipped to Colorado
why do some people use two different radios to build their repeater box, and how. are you running it with only 1?
Sorry I don’t use Instagram. Like the concept.
Where can I purchase this from ?!
Looks like a nice unit but i see a couple design flaws you should consider addressing. Especially considering the emergency and preparedness aspect of radio comms.
I can't tell if there is an internal battery to power everything or just the batteries on the individual components. If individual, you might add in a battery for longer life. You could easily set it up just like the external connection where both devices are fed by USB from the pack.
Those external connections should NOT be type-A connections for convenience as that requires a somewhat non-conventional cord. Yes they are easy to get, but for simplicity it should be a typical connection port like USB-micro or the newer type-c.
It looks like you charge the devices in the box separately. By adding the internal battery pack you could make this a single or double charge connection, all with off the shelf stuff. This would also stabilize charging from a small portable solar panel (10-40w size).
Don't know how much available space is left over in the case but if it's built how I think, adding in a USB battery bank to the case could accommodate the power requirements and connections from the external ports if you have one that supports dual-charging.
It looks like you're using the aftermarket 5R battery that allows USB charging. If you need a radio with the same abilities but smaller footprint look at the S9+. Alternatively maybe one of the water resistant units that uses the non-kenwood connection and secures to the radio via screw. That I don't currently have experience with so don't have a model recommendation though Baofeng does have them.
Great input!!
Do you make one for GMRS?
last question I promise LOL. Do you get anything to take home with you from your classes? Like a completed antenna you make or booklet or anything? Ive seen others offer RTO courses for much less money and you get stuff to take home that you make during the class or is this just knowledge you take home with you?
I usually bring some goodies to hand out at the classes, but the primary value is in the knowledge that you bring home from the course. No item that I give you could replace the value I share with my students. I’m sure there are courses for much less, but I’m confident that the course we teach is worth every penny spent! I teach practical information, coming from a military background and experience in communications, that can help you apply radio concepts to what you do in a meaningful way. This is not a hobbyist course!
Where link to buy?
Just ran across this channel. Good presentation. If you've covered this already, my apologies but if not you could open another product line focusing on NVIS local comm's for those customers who don't want to be triangulated on and found.
Thank you! It is possible to DF NVIS. Although I have had some ideas for HF products
can.a repeated be suspended from a tall tree or off a building? Does orientation matter?
Orientation only matters for the antenna. For the included antenna you would want it as vertical as possible. You could change the antenna to something else though, but it's not the Orientation of the case that would matter just the antenna.
Cool shirt, where did you get it ?
In theory you should both only hear each other once anyway if your out of range right ? Why do you need to program radios on different channel?
Yes that’s correct. And you don’t need to, it’s just another way to do it.
I want one
Would you be willing to sell just the back end board for people that already have the radio or enclosure or just want to tailor this repeater a little more specifically to their own install?
Your best bet for something like that is to get a simplex repeater board from Argent Data Systems or Surecom or something! They already sell them
@@MojaveRepeater awesome thanks for the input!!
Have you compared the revis 97(I think that's spelled right). It's a duplex repeater about the same size of your repeater that you have.
I have not compared it but that would be a good idea to do
@@MojaveRepeater I'd like to see you do a review on them, if you get the chance.
Hello, can it be done with a Tidradio H8 of watts?
What antenna did you use?
10 Watts
Great job. Can you make some on antennas
Yes great idea! I’ll add that to the list
Very cool, so where is the how-to-build or whats-under-the-hood video? 😆
Why not use the UV9R only slightly more expensive radio with a much better plug that doesn’t pop out.
Only 1 radio inside the box ?
Never use autofocus when shooting a video. :) Question does it have to use two usb cables to charge or were you doing that just for the video to show you could do that?
The purchase includes just a single USB to USB cable!
You guys should build a more powerful radio like the new BTech 20V2 I know it’s GMRS radio but it also has a K 1,jack so you can hook up your repeater controller.
What will be the difference? Just curious.
Please make a build video
Can these radios frequency hop?
no
Can also use solar for longer power
Great point! Maybe I'll do another Lunchbox tips and tricks video where I compile some more tips like this
add a DC in plug, like an XT60 or something so we can slap a solar panel/voltage regulator on it and leave it for a few months
I need a tiny analyzer they can show me what traffic is on a bandwith.
Take care of 29 palms for me I miss that place!
You are one of the few that missed it. It’s a great place!
Cool build. But why aren't you providing MURS radios? UV-5r's are not type compliant for the MURS frequencies, therefore not legal to use in that way.
Do you make these for GMRS?
These work on GMRS
@@MojaveRepeater thank you! What is the price point?
@@rockytop441 thank you for that jewel.
Great design , do you make for gmrs
Thanks! This device will work on GMRS
What's the cost
$300 for this unit
Ok sent me info how to order
❤❤❤ 🎶 🎶 anemone slenderbodies 👂
They make solar panels that can plug in to those USB ports
👋🏻👀👍🏻
But if you look up MURS on the FCC database it says No MURS transmitter shall, under any condition of modulation, transmit more than 2 watts transmitter power output.
Yes that's correct. I should have made a clear recommendation to abide by the FCC rules. But of course, this can also be used on channels where that low power output is not a condition.
@@MojaveRepeater Or on radio services that allow repeaters.
@@MojaveRepeater Not legally. The UV-5R is only compliant on 2 meters and 70cm, and if you are a licensed armature radio operator.
Why do you use off set? Its a tedious obsolete function.
You can just use, transmit and received on different frequencies in Channel mode.
1. Set radio to frequency mode.
2. Select the frequency to received on. (444.444)
3. Menu - Option 28 - Delete Channel 0
4. Menu = Option 27 - Select Channel 0 - Receiving memory
5. Exit menu - Select frequency to transmit on. (444.888)
6. Menu - Option 27 - Select Channel 0 - Transmitting memory.
7. Set radio to Channel mode
8. select Channel 0
9. Notice + - at the top while on Channel 0
10. Receive on 444.444 and Transmit on 444.888.
Two ways to achieve the same functionality out of the radio. I wouldn't say offset is obsolete, especially considering that what you've done is utilize the offset just in a different manner. It's a common feature in every analog two-way handheldTwo ways to achieve the exact same functionality out of the radio.

I like your solution as well.
@@MojaveRepeater Something that might help. I see that you using a pelican case. While it is a nice I've found that its possible to get a similar spec case that's waterproof for $12USD. This will dramatically bring down the cost of the product.
You can also just CTCSS code offset the repeater.
Yeah, your method takes way more steps then clicking a few buttons.
OK all you Brainiacs above.
My brain is officially HURTING now.
Someone needs to volunteer to let me EAT their brain so I can absorb SOME of that crazy knowledge.
Or we can trade some knowledge on firearms. Pretty much whatever you want or need to know, I can teach you or show you first hand in trade. 😊
I've got 20 miles with a baofeng simplex.
A bit naff considering the price of baofengs, as you can easily make a repeater using two, eliminating the need to hear your voice twice.
This doesn't exist because there's no links to any of it of where to purchase one
Weird music @ 13:00
Very nice. Too bad the wattage limit on murs is two watts but who cares right.
You mentioned its a 8 watt radio , really ? Maybe you should put a meter with a 50 ohm load on it and check because all the 8 and 10 so called watt radios only put out 5 watts and at 5 watts that radio can still over heat fast so its best to go one level down on them to prevent it from burning up . Now that parrot radio setup is great if someone who wants to hear what they sound like .I have used the units on base stations so the station owners can drive around and check there coverage .
Correct. Bought a Baofeng "8 watt" radio just to test it. It barely made 4.5 watts, and that was the best it could do, and only of some frequencies. They are a cheap way to get into ham radio though.
Hey all you "wut about doing this..." They are selling a product to make MONEY 💰 🤑 💸 💰 🤑 they are likely using the most widely availble affordalble parts as possible. If you want it like your "suggestions" build your own. These are for people that dont know 💩 from apple butter about radios. Im sure these dudes dont want your input on design lol.
So you basically selling end-user radio, but in the box. Which does not really simplify anything (having no extra interface), but instead makes things worse by having an ignition sequence more complicated than small-sized helicopter. Not a great deal.
Radio is not limited by line of sight, btw.
You have no idea what you’re talking about hahaha
Literally the GAYEST music i’ve heard in my life. Say NO to soy already!
All their shit is sold out or expensive af lol
Is this ham radio?
