- This video shows you exactly how to make your own zello crosslink or gateway to analog or to DMR, using only cheap components (except the radios of course!)
I've done some videos on Zello crosslinks before but in this one I wanted to show exactly how to make your own, since I've had a lot of comments asking me how to set it up.
You don't have to use this specific radio. Any radio with the mode that you want (could be DMR, P25, D-STAR, or just FM) and the right style of connector as well as vox can be used. If the radio doesn't have a connector like the one in the video then you may be able to buy an adaptor for it.
Buy the MD-380 or waterproof version, the MD-390:
TYT MD-380: smarturl.it/md380

Clever tutorial. One suggestion would be to add a battery eliminator to the TYT radio so that it can run 24/7 off of mains power rather than shutting off when the battery is exhausted.
Yeah, that could be done. This tutorial didn't take into account things like that but someone could definitely add that to their setup. Thanks for the comment.
Very good. Here's a couple of improvements though.
1. Never plug a radio directly into your computer. You risk burning out the internal soundcard. Instead, use a USB soundcard. These are very cheap to buy, and if you overload it, just plug in a new one, rather than have to open up your computer to replace the internal card, which is undoubtedly more expensive, as well as time consuming.
2. It is possible to buy a lead that has different size plugs at either end, making the adapter obsolete. The lead is no more expensive than the adapter.
3. Many laptops (particularly older ones) are very noisy. Putting distance between the connected radio and the computer may help, although the noise may run up and down the cables. It might be necessary to replace the cables with Bluetooth links.
Thanks
thanks for the good video radiosification.
You're wrong. He had some good and very valid points which may be useful to other people doing this project. He wasn't being negative just for the sake of it, he was giving constructive criticism, which I welcome.
Edit: And now you edited your comment so that my comment makes no sense. Thanks a lot.
@@radiosification Yeah they were offered improvements so I think I may have just jumped the gun. Sorry Gary. Sorry for the interference on a great video as well.
Great another dickhead who knows best, back it up with more than words. Let the guy do it his way it’s his video anyway
Thanks,, for sharing! I really appreciate that you were able to break it down and keep it simple without over-explaining where one's eyes start to glaze over! Great job and if you do not mind I would like to share this with those that my team is needing to connect into their freq. during a disaster or S.A.R. by using your direct video it will give you all of the credit you deserve! Thanks, EJ
Thanks. Feel free to share the link to this youtube video, but I don't give permission for downloading the videos and sharing separately.
This will fry your radio. Many have tried this. It doesn't work very well and forces the transmit to stay on
Good！
Another relatively easier way is using Zello in handphone and walkie talkie.
Both end using extension mic/ear piece and VOX, mic to ear at opposite end device, it is easier to set VOX levels, delay and holding time.
It will be even better using some of the China made walkie talkies which has receive tail suppressions like commercial radios, that is, end of transmissions are clean cut silence !
I love where you are going with this. It is exactly something that I need for my business. And all the apps out there suck. I need a true cross over from a smartphone to a basic analog 2-way radio. Your set up is cool. But cost me a computer. A radio. And the Zello app must be on all the time draining our phone batteries. Wondering if there is a better way of cutting out the middle man. Which would be the dedicated computer & radio. Need a direct push to talk hand held radio to smartphone connection using RF or BlueTooth to communication. Wifi could work, but if the power goes out, what's the point. Might as well use tin cans and strings or pigeons for messages.
Hi, excellent video. I'll be setting this up in Australia. We have UHF CB 476.425-477.4125 80 channels 12.5kc seperation. We also have repeaters (16 channels). Power is 5w. I actually own a repeater GRF08 and will set up Zello for some black spots and local Rural Fire Service can use the phones through the repeater. Will also link another repeater VMD2 to cover wide area.
One thing I notice about this method is that the impedance from the radio ext speaker and into the laptop mic input is critical in getting it working, you must have been lucky with your impedance match. Cheers
That's great. Thanks for sharing your finding with me and everyone else who is reading!
I keep getting interfuwith my uv-5r, i have tried a different laptop and cables, any ideas?
Electronic
This means you using the audio out from the two way radio to generate signal to.the PC, buth carrier is existing wifi? Therefore the smartphone would receive the voice anywhre when he/she got wifi / 3G
How much range can you get off this set up and do you need WiFi or cellular on the other end (radio in the field)
no lol obviously you don't need wifi on the radio in the field. What would be the point in the system if you did? Radios don't connect to the internet anyway
when trying this, the current radio connected to the PC just transmit on it one even if no one is around ,then all you hear is what sounds it come from around the room..... anyhelp on this problem ?
Really easy to follow tutorial mate, going to give this a go next week.
Thanks, and good luck I hope it goes well when you try. It's a good fun project to play with, and maybe even connect to a radio linking channel
Absolutely! Cheers
Haven't got VOX on my MD-380! What firmware version do I need please?
Can i use zello with baofeng uv-5r wothout any programming by pc.. Can just put same frequencies on both zello on smart phone and baofeng uv-5r?
No lol obviously not, otherwise I wouldn't have needed to make this video
I recently got a unided 125xlt is there any way to do the same thing with zello I followed the same steps in your other viodes but that didn't work
it works if I do it with a baofeng programming cable?
Great idea ,but what sort of range are we talking, any chance of a range test video. Thanks in advance.
It is the same as you would get from these radios without the crosslink. The range for all radios depends on a huge number of factors such as terrain, frequency, antennas, weather. It can vary from about 1 metre through a lead wall (maybe even less, who knows) to probably 5000 km or more with complete line of sight such as in space.
this exactly what im looking for, thanks man
As soon as I connect the audio OUT from the computer to the microphone IN on the radio, my GS-5B immediately begins transmitting even when there is no audio coming from the computer. Any suggestions?
Hi, did you fix that problem? and who? please.. thanks
Is this legal with PMR446?
Hi there, I have set this jp and it seems really great, my oroblem is that I can trigger ZW when Tx on a handheld, but cannot seem to open the handheld when Tx on the ZW device.
I've followed all your settings in Legacy app.....what am I missing here...many thanks in advance...
How can you do this with a laptop that only has a headphone port not a mic port is there some sort of adapter you can get. Also does always have to be plugged into a computer or something like that. Thanks.
Get a USB soundcard.
Is there a way to cross link Zello with a CB radio, so that I can catch what a CB broadcasts or the CB hears what I broadcast on my Zello?
Yes, exactly the same as this video but use a CB radio instead with vox and find a way to connect into the mic and speaker output of that.
What’s the talk permit town you’re using for Zello? Sounds different than the default.
Yes now do you change it
Does my Android phone needs to be on a service plans?
how does the radio key up if it from a zello channel. if aux and mic r connected to a radio how do you even talk back on it . help
Very smart! However does this not make it distance restricted?
yes, the radio will only work when it's in range of the one connected to the computer
Ok, this will *NOT* work on a Baofeng UV-5R. only a TYT MD380
First of all, I would like to thank you for the valuable and wonderful information. My question is where is the radio gateway in your system?
Friend, how much does a radio cost and where can I find it?
Nice vid! What is the model of Motorola ?
I only get one way audio.. I can transmit from cell phone to radio, but I can't hear anything on the phone. I have messed with the microphone setting on two different computers still get nothing.
Please help
Thanks radiosification, really like this idea and this video. I use Baofeng UV-82, and the problem of keep transmitting, as previous comments explains, it's about 'Ground loop'. Do I have to by a socket / converter cable to solve the problem? Or you have any other advice on it? Thanks again.
You can actually get ground loop interrupter devices. One of those would be worth a try although I haven't tested it myself.
Did u tried ground loop isolator ? We're u able to fix the issue ?
Lei Zhou
put an isolation audio transformer between celphne spkr out and mic input of the radio
Can I do it DIRECTLY with my MOTOTRBO and my Android phone?
Great video.How does it affect the radio Tx/Rx range.
It should not affect the range at all
Hi there 👋 Great tutorial! I use Zello and two-way radios separately, both for different purposes. I want to do this but I don't know when I would need to do it. Could you give me a scenario when I would need a crosslink between Zello and my two-way radios?
Thanks
I just did this for fun. Businesses who use professional setups for crosslinks usually have an existing radio system and want to connect some new users cheaply or temporarily. Instead of buying or renting a whole bunch of radios and having to get them programmed for their radio system they can use a crosslink and just get people to install a radio over IP app like zello.
@@radiosification Thanks
For me I'm on a ham radio repeater in my hometown. A lot of times I'll travel out of town and still want to talk back to my local guys, so I use my Zillow account to key up my radio at my hometown and I can still talk to my local boys.
I now now how my school's bus radio system works. I thought it was CB but nope. DMR. They have the same keying sound as your Motorola radio
There is a chance that those are analog radios but used xpr radios (you still get the same tpt with analog on xpr radios unless if you disable in cps). Companies upgrading fleet of radios with pre-existing license sometimes don’t update the license, meaning they are stuck on analog even with digital capable radios.
my physical radio stays keyed up when I do this. How to fix?
i wander if those wökkies might be misusable to save names etc or activate such savings once some hysteric freakenntsy is achieveD ?

Hello, Where can I download the radiosification software? :-P
I don't understand. You can't download me as a software
@@radiosification 3:17 I see your name in the software so I though it was an application developed from you, later I saw it was not, please forget my question, I am really noob on this and after read a little I see it is a zello software, so now my question looks a little stupid, thanks a lot for your video by the way
@@rogermartinezhernandez7195 no problem. The name there is just showing my username in zello.
how to make ksun zello communicate with mobile with zello app?
we try this on baofeng uv82 but when we connect the 2 pin cable going to the portable which is in vox already it just transmit always
i have the same problem, have you solved it?
@@SisventTurnero Just strip one of the wires and cutt off the GND wire, make it , so only one of the cable has GND, because it trasmits when both ground pins short out. Hope that helps! Atleast it did for me...
Raymond Santos
buy an isolation audio transformer on line about 600/600 ohms impedance on primary and secondary ,connect it between the speaker output of a cellphone and mic input of a radio to prevent the ground contact on each unit.
what is tha Motorola full name I want to buy it
hello my friend i downloaded zello app i watched your video from play store but zello wants internet and i don't have motorola radio but other smartphone phone to talk without internet and how far is it far if i want otherwise you would write me a reply about it
great video, but my question is, is there any limitation on range? how far we can use the HT ?
The range depends on the radios used. It is not affected by this system at all so they will work just as far as they normally would do.
Question , can you add more zello channels on those portable radios and can you for example take one radio or both out somewhere when they are 20 plus miles away from the phone and still use them ?
So if i get this right your speaker on the radio gets connected to the speaker jack on the computer and the mic jack on the radio gets connected to the mic jack on the computer??
It needs to be mic to speaker and speaker to mic to work correctly.
Hi, is zello work (paid account) account needed ? I've downloaded the desktop app, but it seems I can't use the app without a network name which is a feature of Zello work
Which app can download ?
will this work when your pc only has one port for both mic and speaker?
I belive adapters are available
any instructions showing how to use the radio and a cell phone without the need for the PC?
So as long as dmr has access to zello channel the dmr radio can transmit anywhere
MTH800? And Zello on my iPhone? Possible or not😎
This also goes well with me wanting to record from my Baofeng.
what about using a gp338 moto radio instead of the tyt md-380?
If that radio has VOX, then it should work
Crowd sourcing Zello question: If I am in the middle of a dessert with no cellular or wifi coverage, can I send a message from my iPhone by piggy backing a nearby user who has cellular or WiFi ?.. This a technique used by marine VFF distress call - daisy chain. Same is also used by TILE bluetooth key finder. I can locate my lost key in New York even though I m in LA.
Ive got the leads and the Baofeng UV5R's but cannot get this to work. My PC is an XP. What sort of settings do I need for VOX (level) and does the top or bottom connector on the baofeng go to red or green please ?
how far the distance that zello and HT can connected??
Will this work on UHF? Greetings from South Africa.
Yes, it was on UHF in this video
Hi I tried now but when I use my mobile zello, the app in the laptop go signed out, because another zello is used. How can I do
i dont have radio nor did i ever tried crosslink but perhaps try to create two ids, and add each other up.
This is cool, I am working on EComm in the South USA during hurricane season here and this used with FRS radios and simplex repeaters may give the general public at large more flexible comms options, No license radio persons can link in to a command center which can link out over the internet to mobile phone users. You DO NOT need cell service to use Zello either you can run it off a WiFi connection so any smartphone should be able to use this even if it is not activated on cell networks.
i did this with my UV 5R, it heats up really fast and drains the battery, do u know any fixes?
there are devices you can get that key up the radio for you. One I know of is called signalink but many others out there
The one that is not a problem with the latest version
I have no idea what you're talking about
Excellent explanation .. and a very useful option to know.. thank you
Awesome video, exactly what I was looking for! I would like to see if this can be done using the Hytera PD785 radios, because these radios use a different connection and I haven't found cables online that I can easily connect to the radio and the laptop...
I like the setup and everything but how exactly is this a repeater. Well I need to have the Zello app in order to access the repeater or can I use my radio alone. The signal gets picked up by the radio and then transmitted through Vox on the app. But How is it going to transmit your signal to the other radio
It's not a repeater, and I never said it was!
is this connection consider a voip?what if the other analog radio is in the philippines and im here in japan,can we still communicate?
Hi, wonderful video, a questio here, with this setup can I transmit to the whole network of radios? I mean, no phones with zello but radios? thanks
Well if you just wanted to transmit to radios you wouldn't need any of this. You'd just use the radios.
have you tried to do a cross link from cellphone running Zello and using data to a two-way radio? Basically replacing the need for a computer in order to make things more portable. Instead of plugging the audio cables into a computer, you would plug them into a mobile phone.
I haven't tried it, no. I don't think the mobile version of zello has vox so I don't know how that would work
www.ptt-radio.com/android-em-interface/
Well if they are selling it specifically to work with zello then it looks like it must
radiosification selling? Where?
ok they aren't selling it. I didn't look carefully at the link you posted. But nevertheless if someone posted exactly how to do it then I'm pretty sure it must work.
does the radio use internet to work in case the pesron i want to talk to is not in my state
No. It's a crosslink as shown in the video. The computer uses the internet which is connected to one radio then you can use the other radio anywhere within range of that radio (so probably a few kilometres)
hi, what model radio is the Motarola radio you are using ?
DP4800
Now i have all Google Chrome computers can you see if it will work on them Just a FYI you can now Download android apps on the chrome computers
Why don't you try it yourself then?
radiosification well that is a Short answer
Well if you're already using chromebooks it's the most logical thing to do. It would be much harder for me to test it because I'd actually have to buy a chromebook first!
radiosification ok thank you I will try in and let you know
so did it ever work
What radio is the Motorola
DP4800
its just hard to believe there is still no reliable digital to analog bridges. That Allstar, DVswitch raspberry pi mess is terrible.
Generally it's just not a good idea to make a digital to analogue bridge. The audio is just nasty when you pass a noisy band limited analog signal into a vocoder.
@@radiosification yes that would make sense, however i have a buddy that insists on using Allstar. I cant stand talking on a computer or phone. I do it all day at work. Its a huge drag when he calls me on zello and i have to eat my phone like a slice of pizza with my thumb in the middle of the screen
Is this possible with a Hytera PD665, or a Hytera MD785? Thanks
Yes. you need cables with connectors that fit to your hytera. Maybe you need to do those audio cables. Find the connectors on some special shop that sells Hytera connectors.. or buy external mic for hytera and slaughter that for your project. 73 de santa
Hi how can I get the software ?
download it online
Why not adjust your record and playback on the channel or the audio booster for that channel
Just tried adding your channel on zello, but can't talk/listen/activate without a password. Just a heads 👆
The password is digital
what was the version of that zello you were using? the recent version of zello (2.4) seems to have a bug on the mic. Vox renders useless due to mic issue/bug. (by the way, windows detects mic and works perfectly)
That's unfortunate. I don't know which version I was using in this video as I don't think I checked at the time
it must be 4.75 version and 2gig Ram or up to get fast response
Im looking for a supee cheap walkie talkie that works with zello please help
Would be able to show how to do this with an XTS5000
Not really. I don't have one
I'm wondering: why it doesn't come the user icon on the zello app when tx, instead a little arrow pops up when tx on the channel. .
Not sure exactly what you mean. When you transmit to the phone you see the user who is transmitting. At least, on my phone it does.
I have a problem, we use DMR mototurbo with repeater system, in simplex mode I have no problem, but I can not do the transmission between zello and portable or mobile, will you have any advice? Thank you
This is not a reliable setup for serious applications. It is for fun only. If you want to have a crosslink for a proper radio system then you should not use VOX. Instead, you can find hardware which makes the radio transmit. Contact a business who is selling this type of solution.
I will seek the solution, if I find it in experimentation, I will share it for future communications, thank you, greetings
You could use products like the ones on this page, but this is still not a very reliable solution. If you want a solution with high reliability then it is best to buy a radio over IP with gateway solution which is not using zello.

hi my friend, awesome video.... but i have a dude.... i follow the link on your description about TYT MD-380, but the radio frecuency is UHF... It is right? the motorola radio you use is vhf?
help me with those questions.
Thanks!
No the Motorola is UHF too. The radios have to use the same band otherwise they can't hear each other.
Are you using two different Zello accounts, one for the laptop and a different one for your mobile phone, because if I try to use Zello on my mobile, it signs me out on my laptop, and if I use Zello on my laptop it signs me out on my mobile phone, thanks in advance
Yes I am using two accounts
So with this your basically using your computer as a form of repeater ?
No, more like a gateway. It's not a repeater because when you talk into it, it doesn't repeat your signal back out at all. Only receives it and sends it over the internet
Ok, is it only possible on HAM or could it be for GMRS too ? Because im trying to find a way to access through my radio which is a baofeng UV 5R TP
@@MultiRacing69 with DMR you couldn't do this on gmrs, but with a normal analog FM radio made for gmrs you could. I don't know whether it would be legal
Ok thank you for the info, and I believe it's probably not , somewhere in part 97 ruling their is probably something In there. I will have to look up.
how do you set the channel ??
Do I need a DMR ID and call sign for this
Standard radio operation rules apply. Amateur/license only Freqs will require a license. Analog mode, of course, does not require a code of any sort. I'm not very knowledgeable about DMR but if you want to use a talkgroup, then yes, you require a code.
You can use this on any system where you are authorized to transmit and use VoIP gateways
Yes.can u pls show us...how to link a walkie talkie to our android phone. So that we can keep the phone and press the wlakie talkie to talk to our friends in a zello group in our android phone...means using zello on walkie talkie
This man is genius, can I use baofeng uv 5r for this???
No, if both mic and speaker are connected to a soundcard the baofeng would enter tx mode.
Your TYT it's version 8200 ?
It's most likely TYT MD-380 UHF-version. He dont have TyMD380Toolz custom public firmware. I highly recommend that!
This is just a relay of audio part, not the actual radio frequency transmission.
proverc prc 930 and 710 military communication tool will work soon internet is not very please tell me something I need a nice man
Sir can you give zello link of your repeater
that's weird, I could swear I just replied to almost this exact comment like a day ago
that was a good video some useful information there
Thanks Gary
It could just be me, but do you have custom alerts set for Zello on your cell phone? The talk permit chirp sounds higher and the roger beep sounds more like a TETRA-one, instead of the standard Apollo 11-ish one. Also like the other Sepura sounds it uses. I'd love to know where you got them :)
Hah yes you are right. The ones on the phone are made to sound like motorola tetra radios, and the ones on the computer are made to sound like sepura tetra radios. I made them myself with audacity, just by finding recordings of the tones online and seeing which frequencies they are at.
radiosification Ah, cool. Could you give me some hints as to how to go about detecting the frequencies of a sound? I've tried generating my own sounds in Audacity before, but even the Motorola TETRA "beep" didn't come out quite the way I hoped it would. Wouldn't mind if you published the files somewhere, either, but I totally get it if you want to keep them for yourself :)
I usually use a program called spectrum lab to see the frequencies. Try using fade in and fade out to get them sounding right on the beginning and end of tones, otherwise you get a click sound at the start and end of the tone which doesn't sound quite right. You have to make the fade in and out quite fast.
I'll create a video on how to do it in a few months and publish the sounds with that, after checking that they are all accurate.
radiosification Thanks! Never thought about that. I'll experiment for a bit.
Looking forward to the video!
Check your PMs
cant you tell de range for the transmition
No I can't. Range varies based on many factors. Most importantly obstructions between the two radios. It could be as little as 1 metre or as much as thousands of kilometres potentially with absolutely no obstructions
Is this using Zello Business, or free account ?
Free
Does this require 2 different Zello accounts?
yes
Can you crosslink anyother radios like this way? Let just ask lafayette micro 4 vhf radio?
If the radio has vox, and has a connector that allows you to get the audio then yes.
Ok if not have vox, you need RT-roI1/2, signalink or Radio Over Zello Controller + RT3. Make video about these.
Yes exactly. If it doesn't have vox then you need to buy something external. I'm not planning on buying any of those devices, but if I ever do I'll make a video on it.
where to get those cables?????
Any big online shopping website that sells electronics
@@radiosification can i use simple AUX cable that i already have?
What do you think I am using? Come on man, use your brain.
When I plug in both plugs into the radio (UV-82) it causes the radio to key up. Don't know why.
2001scoop, W6LDS that is normal
How do I stop it?
it should only happen once when you plug the cables in
Ground loop. When the ground on the mic side is grounded to the ground on the speaker side, it keys. The grounds are connected within your computer between mic and speaker.
any solution for this ? Thanks
