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
You could add a Bluetooth Speakermic, and voila... same thing. but wired is also convenient so you don't have to charge it. or get a spring type USB charging cable...
The right hand one is UHF Citizen Band here in Australia. The middle is AM/FM stereo antenna. The steel whip one on the left is high band VHF, as we have a WAERN (Western Australian Emergency Radio Network) radio in this vehicle as I am a lieutenant in the local Bush Fire Brigade.
Hola amigo, un cordial saludo desde El Salvador, muy interesante el video. Mi pregunta es, hay algún otro link donde comprar el micrófono? El link que subiste ya no está disponible.
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 😇🤣
Sam, I'm in the process of building this, but hit a glitch on the mic wiring.....your diagram doesn't seem to show how I link the mic to the amp/output to plug, sorry to be a numpty on this, also got an earth hum, ............hit a bit of a block here.....help would be great. John
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.
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
Thanks for sharing Question: Why is it my iPhone 6 and the uv3r speaker mic I’m having trouble Making them work /Connecting direct connection ... Using Zello
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
Sam, thank you for your reply. I have actually sourced the same product in UK Ebay, and sorted. The only glitch is the Baofeng spk/mic, as the one I got first has stupid coated micro leads, not sheathed cables....impossible to solder/joint efficiently. Have ordered a different uv3r mic see if it's different. Thanks, kindest regards. John
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
Hi Sam, going to build one of these using components you recommend.......however.......where did you buy the 4 lead pin out block for the main loom wiring.....trying to source in UK is not easy, please supply a link if possible. Brilliant idea.....
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 :)
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
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
What am I doing wrong. I can only get it to work in toggle mode. When I select hold to talk I'm getting no pick up from the mic. Hope its something simple
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
Awsome build my friend good job I would love to build a couple of these units can you provide the parts list mainly for speaker and the amp so i can buy. Thank you so much for sharing good job and much cheaper then a 245.00 network radio.
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
Really impressed, have several redundant devices I may convert, phones and tablets. Can I suggest the use of a "buck converter" in the power line. Typically, this type of device accepts 3.0 > 30.0v input and can be regulated to the desired output voltage to a maximum of around 3.0 Amp. (way in access of the current needed for the type of devices needed) In the unit you showed, plenty of room is available to intsall two buck convertors, one to power the device, another to power the audio amplifier. (just an idea) www.amazon.co.uk/LM2596-Converter-3-0-40V-1-5-35V-Supply/dp/B01GJ0SC2C
Thanks for that, I was considering putting a phone car charger stripped down inside to power the phone but these converters sound like they would be easier than that
Excellent!!! I was thinking of buying a Zello GSM radio and after watching your video I decided not to buy it and reused an old cell phone and took up your great idea, In the same way, I plan to use it for disasters for what is practical, easy and economical. thank you very much! Greetings from Puebla, Mexico.
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??
Yeah good work man. I wonder what the difference is between the mic you’re using and the UV5R microphone which is what I use. I was able to use PTT instead of toggle but figured out the first maybe 5 seconds of my over were quieter, then something in the phone would boost the volume. If I used toggle that wasn the case.
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?
