Baofeng thread?

I still have the 50 mhz antenna extension for the Yaesu, but i never used it. The Baofeng gets mostly used by my wife when we need to uphold communication while i'm in the basement friggin with my cnc machine. that's the main purpose of the Baofeng to be honest

UV-9R PLUS is the newest with 8watts.
Don't buy the UV-5Rs anymore, those have been cost down as fuck and riding on former glory.

UV-9R PLUS
x 2
here get about 1.6 Km

in hilly area

>those have been cost down as fuck
u wot

Baofeng stopped making the UV-5R in 2015 replaced by the UV-5RV2 rebranded to BF-F8+
Foscam/Amcrest sells shitty DMR-6X2, UV-25X2/25X4/50X2, UV-2501/2501+220 under the UV-5R name and are garbage.

If you don't have a SX5 chip you have the shit version.

buy a baofeng if it's all you can afford, but if you want something that doesn't suck ass and can spare 80 buck, get a Yaesu FT-4XR. it's a proper 2m/70cm radio and old fuck hams (which is who you'll mostly be talking to) will actually help you use it.

also, most hams are old fucks

HAM, SDR, and meshnets are based but Jow Forums has turned into a bunch of trap loving fajjets so it's no use OP.

What model to get?
I just want to cover 400 square meters, for two way communication, with cheap walkie-talkie.

>400 square meters
Are you joking? on that level of distance you just need to raise your fucking voice.
The meaning of using a radio starts with distances much larger than this mate.

I have a question.
If somebody would like to listen to police comms in Europe, what would he have to buy?

You're 20 years late. There's no analog traffic left in Yurop for at least a decade now.

I bought a set of uv-5r's a year ago. I know they are the shit tier babby's first radio models, but they are cheap enough that I could afford to buy a set of 5 and give one to a bunch of friends on a field trip, rather than buy a good one just for myself.

SDR stick plus a TETRA decoder program and you're in again.

>400 square meters
Sorry, I meant 40000 square meters.
It's small compound with many buildings made from sandwich panels walls.

That's how i did with some of the kids in my area. They got interested in radio stuff so i bought a 10 unit set and gave them away. Now we have a bunch of people talking on PMR and Freenet here in my village.
My son is super happy about it and i can always keep track on him and call him whenever i need to. He more and more leaves the smartphone at home and has the Baofeng with him.
But i went for the UV3r's instead. Programmed them with my data cable and software to be used on PMR and Freenet only.

Ah nice now we are talking.
Price?

Then almost every decent radio is able to bridge this distance.
You can buy the cheapest Baofeng or other chinkshit radio and get satisfied with it.
But program them with a data cable and software, to make sure people don't rape the ham bands with them.
Depending on the country you're in, they could get in trouble transmitting on HAM-Bands.

What's the ideal

search for literally any SDR thumb drive style thing with an RTL2832U chip inside.
They can be as cheap as 10 Eurocuckmoney and go up to over 100 bucks. Depending on the quality and bandwith.
Then you load some SDR software and TETRIS software from sources you can find on the internet.

SDR Software and I/O drivers are free as well as the TETRIS software. But TETRIS software is hard to find, because "highly illegal"

The most expensive will be a good antenna for the scanner and good quality cable with low losses in db.

>But program them with a data cable and software, to make sure people don't rape the ham bands with them.
How difficult is that?
Are there models without loudspeaker?

>software is hard to find
rtl-sdr.com/bootable-linux-image-with-the-telive-tetra-decoder-now-available/
Use lignuks.

The original program is called "telive" on linux btw.
TETRA the term caught on after telive was ported to Windows

>How difficult is that?
1. Buy matching Data cable and CD from aliexpress for your radio model
2. Install driver and software on your computer (windows only)
3. Connect the cable to the radio and PC
3. create a list of Channels using the available informations about these license free bands.
4. Save the list file
5. Upload it to each radio
Tell the people to not leave the channel mode.

>Are there models without loudspeaker?
No, but there are headsets to buy for a cheap. and in some cases they are already included as a package sold.
When connected to the radio, the internal loudspeaker/mic is disabled and the communication goes via the headsets built in speaker/mic combo.
You can even go fully without pushing a PTT key by using VOX.
But that's not really recommended, because then the mic catches up the noisy stuff surrounding you and others and it will trigger the transmit, disturbing the communication of people actually talking.
Vox implementation in these Baofeng isn't the best. So better go for manually pushing the PTT.

yes, maybe it's easier to find now. Back then, when i tried to find it, i had to really search the web an entire day and finally got some stuff in the darknet.

Somewhat unrelated but after getting me a chink SDR I can see all my devices leaking unintended transmission (with my laptop in particular leaving a SHIT TON of footprint).
What reasonable mitigation can I do to lessen this? All other solutions I found and thought of so far are too ambitious or not viable.

I'm using a Yaesu FTM-350 as well.
The radi of is mounted under the desk, while the display and hand mic are on the desk

what says your virus scanner?

? It's clean. I just reinstalled Debian recently. I'm just concerned about my laptop's bad shielding.

ok, now i understand. You talk about frequencies transmitted by your computers. OK.
I first thought you installed some spooky chink drivers and now it is NSA-sending home.

The signals you catch up are RAM, BUS, CPU and GPU frequencies. Computers stray as fuck.
Keep the antenna as far as possible from your computer, and use a good cable with double shielding.
I have my antenna outside on the roof.

Can't be programed from the device itself?
>need headset
That's issue for privacy.

>I first thought you installed some spooky chink drivers and now it is NSA-sending home.
Where the hell did that even come from?

>Keep the antenna as far as possible from your computer
The antenna is as far as my current setup can allow me, which is around two meters outside my window.

I DIY'd a shitty antenna with power wires wrapped around a thin plastic pole to keep it standing because the one that came with it was very small. Admittedly I have zero understanding of antennas other than their length having relation to the frequency range of interest. Searching around for "basics of antenna design" did not yield good results.
>use a good cable with double shielding.
Can I just wrap aluminum foil on my cables?

>Can't be programed from the device itself?
It can. It's just a hell of a work doing it manually within the device itself. and when you have a several radios to program, you will sit an entire day programming them.
I would buy the data cable and program. It's like 10 eurocuckmoney.

>That's issue for privacy.
These Baofeng radios are not digitally encrypted. If you want such, you have to spend more and go for DMR or DPMR.

>Where the hell did that even come from?
I thought about transmitting network traffic computer related when i read it. My fault.
Since you said "install", i connected the dots and thought of viruses.

No, i use double shielded 50 Ohm cable to get rid of the disturbing signals my Computer setup transmits for a good reason.

I want to clear this up, when you say "cables" do you mean ALL your cables? From power supply cables to mouse cables? Or just the cables the SDR and the antenna uses? Stupid question I know

>getting a license
cringe

>digitally encrypted
I mean someone can hear when he's next to the device.

I ment the antenna cable.
It HAS to be shielded as good as it can technically be.
When the received signal already gets disturbed, no filter and no processor can work get this away.
USB cable is pretty uncritical in most cases. Just don't make it to be too long. But about 50 cm are fully ok.

>I mean someone can hear when he's next to the device.
???
If you use a headset, only you can audibly hear what is said. The person standing near you can't hear what you hear unless he's also having a radio tuned in on the same channel.
Or did i understand you incorrect?

I mean the device would be used by multiple people, so sharing a headset is kinda of big no for them.

Ok, you never told me that.
I don't know what your needs are.
How many people will use the radio or radios?
Is every person having/using his own radio?
Do you need encrypted radio communication because of security issues?

Ok, I probably need to elaborate at this point.
>compound/field hospital about 40000 square meters made of aluminum sandwich panel walls
>middle of nowhere
>cell phone reception is somewhat OK
>need 5-6 devices, one in the ER building and the rest is given to each specialty to call them
>the ER device would be shared by 15-20 person
>security wise just measure against eavesdropping

Well, if it's a hospital, then you should go for digital encryption.

The Retevis RT3S DMR for example, is a good radio with encryption. and it also has dual band.
It gives you the possibility to group users, lets you send text messages and so on.

But it starts at about 100 Eurocuckmoney per unit.
So they are a good bit more expensive that the Baofeng UV5r or UV3r

too expensive, I need something that won't exceed 100$ in total.

then you have to go for some cheaper Baofengs like the UV5r
they are about 25 bucks each. so it would be near the 100 bucks in total.
But don't let patient data to be communicated then.

>patient data
it's in third world country, so this doesn't really matter, and it only used to call the sub-specialty to the ER.
Is pager still a thing?
Or is there something like telephone exchange but wirelss?

both pager systems and wireless telephones need a somewhat built up infrastructure to work.
The cost for this would be much more expensive than Baofengs

Dont use the shit software they provide, use CHIRP. Its in actual english and runs on linux or winderp

the chink software worked well for me, but maybe CHIRP is better. I never tried it.

Bullshit it takes 10 minutes to set up a baofeng uv5r so no need to buy a fancy cable. All you have to do is reset it so all the already programmed channels are deleted then find the list of the PMR channels and their frequencies and save them from there on out. But I don't recommend it since you'll have to change power and band setting every time you turn it on and off. Just learn the PMR frequency of channel 4 it's 446.046 and double click to change the channel.
VERY IMPORTANT: If you don't want FCC on your ass (won't happen but better safe than sorry) then you should transmit on low power only ( TXP = LOW) and set your band to narrow so you won't transmit to any other channels. Also set your STEP to 6.25k. That way you have a walkie talkie that's covering quite a distance.

>Bullshit it takes 10 minutes to set up a baofeng uv5r so no need to buy a fancy cable.
Read my comment again. I talked about setting up like ten or more Baofengs and not just one.
Also, there are not only 8 PMR channels, but 16 now. even more if you go digital. Then we have the additional six Freenet channels on 149 Mhz and LPD channels which are 38 channels.
Good luck programming 10 Baofeng UV3r (which i bought for my son and his bunch of kids).
It will take an entire day programming them manually.

This!!!!
Programming them is a hell, especially when you have to do it with a bunch of them.
Better go programming them via cable. That way you make sure all Baofengs have the exact same channels on the same memory channels.

The cable gives more in-depth settings, such as being able to name channels
>since you'll have to change power and band setting every time you turn it on and off
It also enables you to avoid having to do that

Fucking poorfags shitting up my radio hobby.

They’re not good but they compete handily with radios from 20 years ago just fine.

The good thing about these chinese radios is that they brought many people on the ham bands. The entry into the hobby was way too expensive for most people before they came on the market.
Try making younger people interested in HAM-radio, they will not be willing to spend huge money on something they can do much easier with a smartphone.
Because that's how they see it.

Think of it this way gramps, either your hobby stays expensive and dies out when oldfucks like you do, or prices on entry-level gear drop and normal young adults are able to participate and potentially become interested in the hobby as well.

Can someone recommend a good portable antenna for 70cm? We've been using SRH-805S (fake) ones, which seem to work OK (12km range from urban to forest, but the radio weather was probably fucking great then), but seeing as they are fake, I know there's room for improvement.

forgot to mention, I'm in Europe.

Antennas from Nagoya are good. They are a little longer but extend the radios range by a good margin.

What attracts people to HAM radio? I don't see the appeal at all. I mean maybe it would have been neat in 1975 when you rarely spoke to people outside of your town unless you had a pen pal, but what is the point nowadays?

Internet free, censorship resistant, low infrastructure communication.
Also muh sekrit club

It's also about the technical challenge to contact people from around the world. It's about to improve your own setup and antennas and stuff, having friends locally to talk to every evening and a lot more.
Sure, you can do all this with social networks or messengers, but it's still feels different to talk via a radio to your pals.
We are a group of people that talk almost every evening about this and that. It's a lot of fun sitting at the desk and having a conversation about tech, politics, society and many other topics.
Since it's not encrypted all people having a radio could join the conversation. And that happens also. Some of them stay and become friends, some are just heard a few times and then leave again.

It's hard to describe the comfyness with radios, but it's a somehow more exciting way of communication.
And it's totally independent from the cell phone network, from internet and for some people even from the power grid, because they power it via batteries charged with solar panels.
So in a SHTF scenario, the communication system stays functional.

The ability to communicate with no existing infrastructure

I got rid of my UV-8R.
Everyone has moved to bluetooth headsets while out riding.
Zoomers all have these HAM radio emulators on their phones and unlimited data.

I was also too lazy to go study for the supposedly hard to pass license and the cops were starting to pull over anyone who had an antenna and I couldn't pick up anything at home.
I live in a condoplex so I couldn't even dream of setting up a long range antenna to try to bounce signals off the atmosphere and having an antenna outdoors is a sure fire way to get myself vanned.

>intellectually stimulating
>cheap
>useful
What's not to like?

Several things. First is that it an 8 Watt model, whereas the UV-5R can only do 5. It has improved heat syncing, which is important. The UV-5R has overheating issues when you're constantly transmitting on high power. There are firmware bug fixes. Lastly, it has a larger stock battery.

This.

Also it requires windows only drivers directly from ching ling....

Why can't you use Chirp or GNU radio which are on linux?

In the future when Google bans you from the Internet for saying 'nigger' that one time it'll come in handy.

My radios were all programmed using CHIRP on OpenBSD, cable worked fine. It's just an RS-232 to USB adapter so if yours for some reason doesn't work, make one that does.

Nice!
Good to hear

since we are talking about SDR and shit...
what's a better alternative to GQRX?
also, we should make a RF general, IMO. not that I know shit, but I love this SDR stuff.

Anything that isn’t exactly what they’re doing is “killing ham radio”

What’s killing ham radio is boomers.

Agreed.
If we can have a desktop thread that counts as "tech" then we need a RF general at the least to live up to Jow Forums standards.

Even plebbit makes us look like fucktards these days.
The constant trap threads and laptop sticker threads are destroying my soul.

actually, its the FCC government faggots banning encryption over ham, and cracking down on 'unlicensed' operators

cry more faggot, hams hunt people like you for sport

>license
>hard to pass
It's not, apply yourself brainlet.

>cops were starting to pull over anyone who had an antenna
Where the fuck do you live, bongistan? Here in SF Bay Area I often see boomer hams with 3 antennas nigger-rigged to their shitboxes and no one seem to bother them. They often have their callsign as a vanity plate which is probably the most boomer thing you could ever do.

>Zoomers all have these HAM radio emulators on their phones
Agreed that's just fucking gay.

>tfw I just bought a truck and am getting an amateur radio license plate

Enjoy everyone being able to look up where your new truck is parked in a publicly accessible online database.

You mean my PO box?

I live in the asia pacific, and they pretty much want no one on the frequencies pretty much only taxis, buses, lorries and emergency services have radios. Radio sets have to be individually examined, tested and licensed, when it's replaced it has to be unlicensed and they keep your equipment you get a max of 5 licensed sets your equipment also needs to be retested and license renewed every 5 years.
It's a 1.6K USD penalty if you're not licensed and equipment gets confiscated, if you're licensed but your equipment isn't, you still get fined for the equipment and the equipment still gets confiscated. Baofengs usually can't be licensed unless you go out of your way to lock it way down and handhelds are limited to 5W or less meaning the better 8W baofengs can't be licensed here.

Class 3 is limited to 25w or less here.

They claim that normal citizens have no use for a radio unless they are doing illegal shit. since cell coverage is great

No it's simply Jow Forums.

ok neetbeard

Good lad. Many wish they had this foresight when first registering with FCC.

Maybe because most people who buy these cheap pieces of shit have no plans to ever get licensed. They illegally transmit on the FRS/GMRS bands and kerchunk repeaters. Then, if they actually do use them in a legal way, they are barely intelligible due to being constructed with the cheapest garbage components available. You can buy a brand new stripped down Yaesu for $70, but people would rather buy trash for $35. People can't comprehend what happens when idiots are out transmitting with dirty RF. It shows up as interference on other frequencies and disrupts other services.
