Home Made Zello Network Radio 

Just buy a Bluetooth microphone speaker and use your phone..😎👍🏽

In a disaster, a network radio would be less than useless. Cell towers get overwhelmed in emergencies. Network radio great for all other times though. Crystal clear limitless communication!

You know that approach needs main power to power the circuit, right? And you need an internet connection and a modem & wifi router right? You know that a GSM is completely portable and their is not monthly fee, right? How is paying for a monthly internet connection and all the required infrastructure, more practical and economical??

G'day John, I just used breadboard/arduino/protyping jumper leads as I have a bunch of them and they connected onto the amplifier PCB perfectly. www.jaycar.com.au/jumper-lead-mixed-pack-100-pieces/p/WC6027 This is an Australian shop link but I'm sure they are reasonably common. Hope this answers your question, I'm glad you like the idea :)

You have to open up the mic and de-solder some of the wire and swap them around to output to the correct pins on the phone side, I have done it but can't remember which ones I switched around

I have updated the video description with the links to the items, the links are from here in Australia however I'm sure similar items can be sourced worldwide easily

I think the uv3r's mic I used doesn't fully short the mic pin so the phone picks up only partial resistance which Zello can pick up for the hold to talk. When I was setting them up the toggle mode didn't work well at all

@@samthefarmingman1039 Hi sam Im the opposite from you. TOggle is working great but PTT to completely silent. I too am using the more modern baofeng mic for the UV5R Do you think its a ground issue on PTT?

How I order?

Hello to El Salvador from Australia! To purchase the mic simply search Ebay or similar sites for " BF-UV3R Speaker Mic ". The link I included was for example purposes and are no longer in stock as I bought the remaining ones the seller had to make more of these radios 😇🤣

@@samthefarmingman1039 gracias Amigo, lo encontré, espero realizar el proyecto, veremos como queda. Saludos cordiales.

Yeah, you'll just have to use an app such as lesser audio switch to witch the output from the wired speaker to the devices internal speaker. You can open up the mic and rewire it. I've done this but can't remember which wire I re-soldered to where

I do't sorry, something I haven't played around with yet. I suggest looking at Lewis Ringway's videos, he has a few on crosslinking

@@samthefarmingman1039 thank u very much..

Nice work man

All you have to do is wire one of the audio jacks from the phone to the input side of the amp, and then wire a speaker into the output side of the amp. I also get an earth hum, but it doesn't effect the operation for me, I have one mounted in my office and one in my vehicle so doesn't bother me.

@@samthefarmingman1039 You should use a Transformer or Opto Coupler to remove the noise.

It doesn't matter how you connect the power to the amp. I just used some project 'link up wire' to connect onto the amp module, then used them again on the outside of the radio so I can disconnect it from my power supply if I want to

I'm afraid using the uv5r mics only work with toggle. I was doing some experimenting and the uv5r (and uv82) ones completely short out the pin, whereas the uv3r ones only partially short out the pin, making it possibly to also carry the voice over the same pin. Hope that makes sense, if I were you I would just stick to the toggle mode or swap it out with a uv3r mic

@@sammarsh5480 thanks Sam. Yeah im getting used to the toggle only method. Great video. Thanks

The red and black from the mic are just passive for voice, controls etc... they are not live power. I have soldered everything together and the live power is separate running straight to the amplifier module. Hope this answers your question

This is just a different type of radio. They're all over Amazon and eBay from companies like Radioditty. They're simply network radios, operating over an internet network. I agree that a traditional RF radio that transmits radio waves is the best when it comes to reliability and dependability. But most of the users for these are for applications where that necessity during an outage would not matter.

based on your limited view of what it is and is not but for others we recognise that most of the time we are not in the middle of nowhere nor are we going through the apocalypse and wish to use the technology available to us to solve the issues we have also Tetra Radios work almost exactly the same as this does with the only major difference being is tetra is a proprietary system of using Cellular Radios to achieve the same end result so yeah if the world ends sure radios will be usefull but untill hen theese to more than radios can do they can communicate over near infinate distance provided theres internet which is most places they dont require specialised licenses so anyone can use them (zello in particular has seen the rise of the CB style radio all other again) they dont require fancy setups for antennas and amplifiers and choosing the right location to deploy them they judt work and its accesible to nearly everyone theres dozens of reasons to use POC radio and before you come back and say but its not radio just remember that the technology for streaming audio broadcasts over the internet to listeners is called internet RADIO and theese use cellular gsm radios to talk to the cell towers which is no less real radio than ham operators using repeaters (remember in a apocalypse if the repeaters go down you ainr talking far at all so leave us to have our fun you have your fun and together we can have fun

Um, cos it's too painful to set that up and the whole idea is to have radios that are always on. I did do what you suggested but too hard to setup and connect to bluetooth constantly etc, and who doesn't want something that looks like a conventional radio! I don't appreciate the rudeness of your comment, it is not what this hobby is about
