I bought one and started pulling epic pranks on truck drivers like reporting false weather and traffic. Now some guy named "big horse" says he's going to kick my teeth in.
Anyone else encounter this.

potentially crashing a semi into a twingo, causing a 50+ car pile up and the most deaths in a single car accident in your country's history
>Anyone else encounter this.
>>55434197
Got this at the advice of /k/
Works super well for listening to local police stations.
Wish I could talk to truckers with it
>>55434411
But this didn't happen. So it was harmless fun. I'm worried because this guy seems about 11 miles away from where I live and he keeps checking in trying to talk to me with locale updates.
>>55434197
what kit do I need to talk to truckers?
I'm going to need to buy a new scanner that does digital decoding (specifically P.25) because I'm moving to a town whose police force just upgraded to unencrypted P.25.
Any recommendations radio /g/ents?
>>55434594
A cb radio from the 1970s and a decent antenna.
>>55434197
careful anon, the fcc can hunt you down and fine you. Also they can tell what direction you are in when you transmit.
Pic related I just bought one of these anyone else have one?
>>55434708
Does it work
>>55434497
From the filename and google it's the BaoFeng BF-F8HP, right?
Do you need to do anything in particular to access the police scanners or just tune to the right channel?
<-- This user is a dumbass who listens to that shit on the internet and has never used a radio before but is curious.
>>55434708
Is there any chance of getting USB transmitters in the future or is that completely out of the question?
>>55434708
>anyone else have one
I've got a few.
>>55434620
Not sure if you want this but with an cheap rtl-sdr you can decode p25. Not sure how good the performance is to an actual scanner though.
Pic related
>>55434738
Yea, i misplaced the - in the filename, it is a BF-F8HP.
I can listen in on public frequencies by getting the frequency band online and loading them all through the chirp program and a usb adapter.

top kek. nice work
>>55434197
My papa just recently started getting crazy about Ham radio. I am way more interested in camping style survival stuff.
I have a slight interest, but I just don't think the world is ending.
>>55434738
>Do you need to do anything in particular to access the police scanners or just tune to the right channel?
It depends on the PD. Mine is a suburb so they broadcast unencrypted on 3 freqs; main, traffic and admin. Bigger cities have trunked systems. I've reached the limit of my experience but I don't think the entry-level chinese radios do trunk-tracking.
>>55434556
He'll probably fox hunt you. I'd call the police if I were you.
>>55434778
>>55434807
Thank you for the insight. I'll do some more research on my own (Particularly about trunked systems) but this gives me a good place to start.
>>55434755
For the rtl-sdr you can do a tiny amount of fsk http://www.rtl-sdr.com/an-rtl-sdr-to-rtl-sdr-qso-with-rtl-trx-transmit-rtty-with-the-rtl-sdr/
If you want something proper I think a hack rf is around 300 dollars.
>>55434721

Tell him he's a cocksucking faggot who frequents glory holes at truck stops.

Share it with /g/ pls.
>>55434708
Aye. Mess with it occasionally but it usually sits in my closet. Still work the money if you are interested in amateur radio. Works great with GQRX.
>>55434773
Are you trunking?
>>55434197
in gonna kick yer teeth in!
>>55434873
No, right now I only have one dongle. I think seperate police groups use a bandwidth over 2.4 mhz so I can't properly listen. Either that or I didn't set up the software right. If I had two dongles I could have one set on the control frequency and one listening to audio.
>>55434346
Hitler did nothing wrong it was all harmless fun.
>>55435034
If you get unitrunker working with the sdrsharp plugin, it will listen to the control channel for radio data, then swap back and forth so you can selectively follow a talk group.
Single dongles do work, but every couple seconds, the dongle has to switch channels to the control channel(data) to see if the voice channel is still active.
I need a indoor antenna I can put on a window. Ihttp://www.wa5vjb.com/references/PlanarDiskAntennas.pdf I know next to nothing about antennas so I was wondering if this would be ok. I am mainly interested in vhf and uhf. Right now I am just using a really long telescopic antenna.

>>55435284
You don't have to bump a thread after five minutes, and numbers stations are usually on shortwave.
>>55434842
Op yes
>>55434708
what does this do
>>55435528
Plug it into pc and recieve 24-1700mhz. You can listen to analog audio or decode digital stuff f if you want.
Figured I'd post here instead of making a new thread, but does anyone know where I can get a cell phone jammer?
>>55434708
I have one of these.
Using it to track commercial planes
>>55435611
can I use some of these to make a theremin?
>>55434755
Not enough power over USB for anything good.
>>55435634
Ebay maybe? If not idk maybe buy a cheap radio that can cover GSM frequencies. Be careful because it is highly illegal to transmit (jam) on those frequencies. Like a federal offense. https://www.fcc.gov/general/jamming-cell-phones-and-gps-equipment-against-law
Anyone into websdr?
http://websdr.org/
>>55435797
Not really, from what I just read from Wikipedia about theremins you need something they can transmit at like 500khz. These things can't go below 24mhz and they can't transmit sound, only small amounts of digital info experimentally.
>>55435880
I've played with it a bit. I just wish not everything was sw.
Is there any reason to get a CB radio I've always wanted to get one.
Baofeng UV-5R + DE1103 + rtlsdr + CEPT full license reporting in.
OP is a fag, and I fully agree with >>55434197 gentleman.
>>55434497
where the fuck do you live that cops broadcast on 2m/40cm
>>55436675
I think my state only had one 800mhz license, and that that lapsed a decade ago.
>>55434708
dont buy nooelec or offbrand china shit like you have in your pic
they all work fine, but for a few bucks more you can get a much better unit from rtl-sdr.com
with aluminum housing , thermal pad and proper antenna port

what? aren't those comms encrypted?
At least in my country all police communications are P25 and encrypted.
>>55434620
It's useless if they chose to encrypt.
My PD in Europe uses Tetra.
Any chance of decrypting that?
>>55434755
You cn use a hackRF to transmit, I've used one to jam the tv in my neighborhood, with an amplifier obviously
bump
>>55434197
tell them to meet you at a motel and bring some pink champaign.
>>55434197
The FCC has zero sense of humor. If you start enough trouble. They will have some of the local hams triangulate you. Pay you a visit. Confiscate your gear and leave you with a fine. It happens more than you think.
>>55436227
No it's trash. Ham is where it's at.
got me one of these, it was only $30 odd so no major loss but I wish I had got a UK CB radio or a shortwave radio instead as the local ham repeater is noisy as hell and the squelch settings aren't good enough to deal with it and the scanning speed is too slow to find anything interesting
police and other emergency services started using tetra a few years ago and pub/shop watch use digital, leaving buggar all commercial stuff and most people on the CB (27mhz) frequencies
so I feel like if I go ham I'm going to be shit out of luck until I get a licence and start getting bigger and better gear until I can start picking up signals ;.;
>>55437292

>>55448795
Also wanted to do that, brought one of these digital TV adapter (just like the pic on >>55448608 (except it is blue)), but the only thing I managed so far is listen to FM radio.
>>55448795
usb radios don't send sound to the computer. They send the raw signals which are then processed into sound by the computer. https://www.amazon.com/RTL-SDR-Blog-RTL2832U-Software-Telescopic/dp/B011HVUEME?ie=UTF8&linkCode=sl1&linkId=e6b872ce4bf757ba9f71fbd35a53742e&ref_=as_li_ss_tl&tag=rsv0f-20 (rtl-sdr) can cover police and cb frequencies. If your pd uses trunking or digital radio things can get complicated.

>>55449749

>>55434497
That's a HAM radio dude.
Unless you're licensed, don't transmit. You decide to harass other people with it, eventually local operators will fox hunt you and either
A: Kick your fucking teeth in
B: Have the FCC fine you into your next lifetime.
Though HAM radio is a good hobby; should look into getting licensed.
>>55449891
Having seen a few HAM guys in my time, I'm going to say B is a lot more plausible than A.
>>55449891
The whole FCC thing is a little overblown. It takes alot on the HAM bands to get the FCC to come to your door.
If you are transmitting on commercial, aviation, or civil, you should expect a visit in short order.
>>55449972
CB and GMRS the FCC doesn't really give a fuck about unless you're doing something really retarded like creating a shit ton of noise or havoc for an extended period of time, enough to get attention.
HAM Radio operators who did the work and tests covet their bands and if they hear someone fucking around they'll do whatever they can to nail you.
>>55450012
Yes they can complain all they want, but the FCC is VERY lax in enforcing. They closed much of their field offices a few years ago. Budget cuts, etc.

Do it without a cellphone infrastructure.
>>55434637
Not entirely correct. At some point, CB went from 23 channels to 40 channel. You'll want to make sure it isn't an ancient 23-channel CB radio.
You can also get a HAM radio and mod it to transmit on CB... I don't recommend this however, as the FCC will fuck you up.
CQ CQ CQ THIS IS N6-FUK, EAT MY ASSSSS
>>55450141
Neat.
>>55434497
Push the big button on the side anon, you can probably talk to those police on it. Sadly they don't do a triple band version.

>>55451190
don't
>>55451190
he probably programmed it with CHIRP and disabled TX on those channels.
just make sure you're always in a moving vehicle while transmitting to prevent triangulation.
>>55434197

Get a HF rig with a tower pleb.
Actually just get yourself a license. A retard can get one.

Any Chinese eshop, yes, and sure, if you're close enough to them to get murdered.
>>55456948
Does each /walkie talkie/ have it's own frequency? or is there channels that must be used?
Or there are some fixed frequencies?
Also Shouldn't these be encrypted?
>>55457045
A HAM would be able to answer more precisely, but generally frequency ranges are marked by "steps", 5mhz, 12.5mhz, etc. A consumer grade radio would have channels based on those steps. ISIS probably has much better military radios they've captured or scavenged but I'm not able to speculate beyond that.
>>55457125
I see, now if I want to set up a radio broadcasting / receiving station.
With minimal hardware/software, what do I need?
>>55457167
Enough motivation to research this yourself instead of expecting a spoonfeed. Fuck off.
If you don't know "you are listening to" do so.
http://youarelistening.to/
Police/emergency services broadcasts mixed with awesome ambient music.
>>55457167
Depends on how far you intend to broadcast, on which frequency/ies and how legal you want it to be.
If you only want a range of a few miles and don't care about the law, a $40-50 chinese HT like >>55440394 or >>55439341 and free software like Chirp would do... plus whatever the FCC fines are when you get caught.
If you intend to set up something permanent like a repeater, you'll need a HAM license, a decent antenna (maybe even a homemade tower in your backyard), an amplifier... and radio guys always end up collecting odds and ends so there's no real limit to how much you can spend.
>>55457237

>>55435019
underrated post
>>55450373
There's an app for that, you can also plug SDL antennas and software and do wayyy more than any dedicated HAM or CB garbage.
>>55457333
Listening to cops, etc: depends on what equipment they use. They might be trunking, they might be encrypting... or they might be using old hand-me-down radios that >>55448608 can pick up.
If you're interested in a specific city, there are hobbyists who stream police/fire/EMS radio on the internet. If you can post here you already have the equipment you need to listen to those.
Broadcasting on AM/FM... There have been low-power FM kits since forever, just boost with an amplifier and have a decent antenna.
>the law is only concept
If you use police transmission in the commission of a crime (including attempting to disrupt their communications) they'll find out sooner or later and, like you said, the law is just a concept to them.
>>55457460
>If you can post here you already have the equipment you need to listen to those.
Not really.
>Police
Where I live the "police" do nothing.
It's a corrupted world where we live.

How would they do that?
Doesn't this mean that I have to be OnTheAir all the time?
Just bought an old CB at Good Will the other day, gonna have to take it to a radio shop to see if it works before I put any money into an antenna or a power adapter
>>55458195

Ham here.
For walkie talkies and CB radios, you are restricted to a set of channels. If you own a HAM radio, you are only restricted to a range of frequencies (or bands), such as 144-148MHz. Most radios now a days have pretty good selectivity, and can adjust its frequency by ~5KHz steps. If you do some math, 4MHz/5KHz≈800 channels. Plenty of talking room there.
I don't really know what you mean my 'fixed frequencies', but I do know 144.2MHz is national calling, channel 16 on VHF is a harbormaster/emergency, and 9 is normal talk. Take a look at >>55450099 for more info.
>>55460297
you really sucked at math eh
the only way someone needs a 3 team to actually get your ping is if you live on a place with lots of skyscrappers a lot of people and no way to use the gps...
like the idiot using the skyking channel on uk and got busted like in 1h
>>55460297
2 teams. I have no idea how the FCC does it, but damn it works.
>>55462000
I commend your trips.
Where I live FCC ain't got shit on me.
I've been doing some broadcasting with RPi, for the last six months.
But the range of 7 miles isn't good anymore.
Also I want to broadcast over channels that are being used, rendering them useless.
I wasn't joking when i mentioned ISIS before.
>>55461032
Nope. As long as you're on a legal frequency, you're fine.
>>55462000
Sometimes 3 teams is necessary. How many GPS satellites do you need to be connected to in order to get ones location down to a few feet? Hint: see pic related. Most of the time you will just need 2 teams for ham.

Fuck you, OP.
You're an asshole. There's no reason to shit up the radio waves with your 'jokes'. They're not funny for people trying to use some stuff to get their job done, or even the hobbyists. You're a dick, OP. Get fucked.

1.3ghz ham band is neat for drones. Better than using 2.4ghz.
>>55434197
I have these radios. Recently a friend and I also got 6 Kenwood tk-3100s from my university's surplus store, and we only paid $25 for all of them together.
>>55467207
I also installed a serial card for programming radios with CHIRP.
>>55467317
more?
>>55467361
Here is one of the tk-3100s.

actually you broke the law and can be subject to fcc fines in the five figure range. you need a ham radio license to brodcast. i know for a fact that if you lived where i live there are many ham radio operators that could triangulate your broadcast location in seconds and send a report to the fcc. they then dispatch an investigator with monitoring equipment who will track you down and hand you a fine.
the ham radio people really dont fuck around. they take that shit very seriously.
>>55449409
CB? no they don't. HAM radio on the other hand they enforce and have the ability to hand out MASSIVE fines.
>>55467207
nice anon. is that baofeng sporting a nagoya antenna? i have the slightly newer model with that extended battery and a nagoya na-771 whip that i use for paintball. amazing little radio for the price!
>>55466896
depends where you live. i have a ham licence, live in metro detroit and there is a real good repeater on top of the renaissance center that can reach 50 miles. once a week the club that owns it holds a check in show where they do trivia contests and shit. regular nights there is discussion on politics, technology, cars or whatever. the other night people were trying to help a guy fix a problem with his car. it's like a chat room. pretty fun actually.
>>55464449
i would recommend picking up a cheap little baofeng for $30 and listening in on the ham scene in your area. if the people are cool and you want to chime in pick up a basic 50w kenwood ham radio for ~$200-$300 and go get your license and start learning the jargon.
73's anons
>>55466675
for when the internet is censored to shit in the comming years
>>55466675
other than an emergency the only reason is for the hobby. think of your local ham repeater as a kind of low tech chat room.
>>55467544
I think that is the antenna I have, my friend ordered them so I am not sure.
Baofeng does make some nice budget radios.
G'day cunts, what UHF portable radios would you guys recommend? Looking at a either one good one or two decent ones for outdoors and 4wdriving. Was considering either the Oricom 2190 or I think it was the uhf720
>>55467954
if you just want to use them for simplex operation then just buy one of the baofeng UV-5r models for ~$30 and strap an extended battery to it for another $15 and you will have coms for three days or more on one battery
>>55467986
I was looking into that, would it cover Australian channels? Our UHF radios are 40 or 80 channel, not dialing in exact mhz ranges
>>55446173
>I paid for this gun so I can kill anybody I want because it's my property
>>55468037
You just need to get the correct frequency from a chart:
https://en.wikipedia.org/wiki/UHF_CB
>>55468088
Alright, cheers bud; appreciate the help
>>55468037
i think you need to study up a bit on how these frequencies work and what the laws are that govern them in australia if any.
average store bought walkie talkies operate on FRS band. the more expensivee ones can now broadcast on some of the GSMR bands which in the states requires a lisence to legally broadcast on though many people operate the illegally for short uses or remote areas where they are unlikely to interfere with legitimate communications. radios like the baofeng uv-5r are the next step up and can access all FRS, GMRS and HAM bands.
i usually stick to FRS bands unless i'm at an event where there are enough walmart walkie talkies to clog those channels and then i move to the GMRS frequencies that those radios can't use. i use these radios for paintball, airsoft and trail riding. the baofeng is a lot cheaper than those walkies you posted and it can broadcast at twice the power. spending another ~$17 to upgrade the antenna is also a good idea for clearer coms in terrain that may interfere with reception.
>>55467592
Theres the issue i have. I don't live in a city, i live in bum fuck next to no where, not to far to get great internet, but not close enough to really do anything interesting with it.
if i take it as a chat room, ok, i get it, but i honestly cant see myself having to much fun if the only people i can talk to are other people who passed the test ant paid.
>>55468214
ya it largely depends on your local scene. the last time the held a check in show there was 38 people that reported in. now if you still want to get into it but the local scene is dead you can download an app called echolink that requires your ham license that will allow you to connect to a repeater via voip as long as the repeater is set up for echolink coms. the other night someone from Tennessee was talking to us here in detroit using it.
>>55451962
Why not?
>>55442601
I'm not sure why, bury I can't stop laughing at this post. Sure , it's derivative of a hundred others, but dammed if this one didn't get me right in the Keker. Thanks anon.
>>55467986
here's my gf with a baofeng UV-5f v2+ with extended battery, nagoya NA-771 15in whip antenna and a throat mic.
for quad riding you will HAVE to get a throat mic with a remote push to talk button like this one.

Not that annon, but a gun is not harmless, and I can shoot a gun and not cause harm. That does not at all mean that guns are harmless.
OK Computer is the best
>>55450141
I don't understand the vertical "stacking" within a single band. The order seems somewhat important looking at the higher frequencies. Is the stacking to give finer resolution to the horizontal scale? Is the stacking indicative of multiplexing?
>>55434197
record and publish for our amusement
>>55469770
It's to add some additional resolution, but also multiuse.
I do terrestrial work around 1.413 GHz (L-band), you'll notice the three things stacked there are passive. That's because there is a quiet band there where there is a hydrogen band for radioastronomy,

Asking for a friend
t. nigger
Not really my thing; it was more my dad's as he used to take his work home with him and tinker in his spare time too, he used to build radios from scratch and modify them. Mum got annoyed at the aerials in the back garden and loft, and every time you went in his workroom it smelt of leaded solder and you'd find little bits of wire embedded in your sock.
By the way, you're an asshole, OP, and I hope you get hfdf'd.
>>55435284
Many of them don't run anymore. Shortwave radios in the current decade are way, way more suspicious than some regular smartphone.
I saw the "Lincolnshire Poacher" once, or at least it's immediate predecessor before they started relaying from Cyprus. It had a male voice back then, nicknamed George. Huge machine, all boards and perspex, made him look like ORAC from Blake's 7; a proper mainframe. Airlock doors (three in sequence, couldn't open two at once or an alarm would sound), thick bombproof windows with mesh in them. Two rooms opposite the mainframe room with like a serving hatch between them, but you couldn't hear one from the other: I don't know why. Not quite sure what the setup was exactly as I was quite little, but it was run by RSRE/GCHQ up on Birdlip hill. I'm not sure my (late) dad should really have taken me in there, let alone brought home a Torch Communicator (BBC Micro with extra CP/M Z80 shit in a big metal box with two floppy drives and a huge keyboard) for me, but I guess I was a curious little girl, it was being decommissioned soon, and he couldn't resist. Yes, they used Vernam one-time pads.
>>55467490
And it's a shame because the FCC has some batshit insane regulations regarding what you can and can not say on most frequencies
If the FCC forbade reminding people that it was once legal to say "nigger", hams would enforce it. Those autistic bastards.
>>55470006
It's a mutually beneficial relationship. HAMs help enforcement, the FCC makes sure the HAMs keep their frequency allocations.
The legal protection helps both parties.
>>55437292
In EU pretty much all non-shit-tier states use encrypted systems, Matra, Tetrapol and that kind of shit... it's a lot like old GSM, but with stronger encryption.
In Burgerland, everybody can use whatever the fuck they want, so it can be anything from pure analog to fancy digital systems, all depends on how much money the district had to blow and what they've been shilled into...
>>55437394
Chance yes, but requires very l33t hacker skillz. If you know jack shit about encryption - no.
>>55470215
In Washington, D.C. most stuff is digital/encrypted, but the park police and some local stuff is analog. So yeah, even in a single area you can get a whole mishmash
>>55434197
What radio and what should i know about wanting to listen to UHF police/fire in my town? I haven't even picked up my first radio, but i want to know what i should do and how i should go about doing it. Thanks guys

Baofeng UV-5R
>>55470497
No guarantee you will be able to listen to those channels. These days they often use digital radio or a crazy high frequency that most radios can't tune to.
That being said. Baofeng UV-5r

>>55472338
I know for a fact that at least one local ham in my area has the equipment to tell you exactly where you are with a single broadcast. His system automatically plots the location on a map for him. He can tell you what road you're on and if broadcast even twice he can tell you what direction you're driving.
>>55464023
>>55464047
>>55464099
Actually, it only goes down to 1 watt. And by v&, I mean is anyone going to even notice or even care if it's more than .5 watts?
>>55472769
>is anyone going to even notice or even care
If you thought 4chan was full of autism, you should see HAMs.
>>55440154
There's nothing illegal about giving bullshit info on CB though. In fact CB is mostly for bullshit info.
>>55472769
No one will know. I broadcast on FRS at 4watts constantly. Is it against the law? Sure. What are the chances that someone close enough to you has the equipment to detect you? Million to one. I usually broadcast on the GMRS frequencies that Walmart radios can't broadcast on. No I don't have a GMRS lisence but there is no one on the GMRS bands where I'm at anyway.
>>55472813
Not autism. Just the same old men that get upset if you bend a blade of grass on their lawn. It definilty has its fair share of old weirdos.
>>55472813
Former military morse code operator and licensed ham here.
The amateur bands are constantly under threat and hams therefore tend to be very territorial when it comes to abuse. Some bands are already known to be troubled by "lid operators".
>>55472338
>Someobody hasn't been on a fox hunt
I have.
Today's amateurs have access to tech that is better than the military had 20 years ago. With 3 SDR units you can perfrm real time phase correlative direction finding
https://youtu.be/8Wzb1mgZ0EE
With 2 such stations you do triangualtion in seconds.
With 3 or 4 single receivers spread out geographically you can do TOA DF and locate the transmitter within a fraction of a second.
Between Baofeng UV-5R and UV-B5, which one is better for a newbie? Internet reviews told me that the latter has better frontend but it is very hard to get nowaday.
>>55473909
I thing the b5 is the better radio but I like the look of the 5r v2+ a lot more and for a basic simplex operation I doubt you would see a real difference.
Don't forget the purpose of these radios is to provide the proper functionality while remaining at a low enough price point that we can destroy one without worrying to much about the cost to replace it with another. That's where the baofengs shine. If you want more you will need to look at the $100+ models from companies like Kenwood.

This thread makes me want to study for my ham license again. I was getting into it then didn't have time to keep going
Do taxi radios use ham or gsmr?
>>55478312
It can't be ham. Ham isn't allowed to be used for profit
>>55468208
Other person here, If I use frs over 500 milliwatts can they find out?
>>55468340
ilegal
>>55469931
I would imagine the people who come for you are just cops anon.
>>55479024
Yes. The FRS band is reasonably quiet (unlike HF bands) so you will be detected. SNR can be further enhanced by multiple receivers and angular discrimination which gives you a bearing as well.
>>55467629
thanks. the most versatile setup seems to be a decent handheld + the best antenna I can afford.
general Q to thread:
what is required to broadcast internationally? the expected use case is casual talk with foreigners and sending out handmade QSL cards
>>55479435
>what is required to broadcast internationally?
You're probably talking about shortwave.
>>55479575
yes, HF/shortwave. if the end goal is to exchange written confirmation from across the world of a connection on the 160M band, what would be the first step?
besides learning as much as possible, unless you have a specific book recommendation

No its not a criminal matter. The fcc has field agents who's job it is to track down illegal broadcast when they are reported.

GMRS is out there, but most use IB (itinerant business) frequencies.
>>55479024
They "can" end world hunger, but the chances of you being popped for using some non-type-accepted rig are very nearly zero.
No one gives a shit about CB, Ham, FRS, GMRS or any of the other allocations not used by the government or to make big money.
Seriously. In NYC the jammers run wild, even on the police bands, sometimes for years on end.
>>55479670
Hams call written communication a "QSL card", although increasingly they do this electronically these days on sites like qrz.com.
160m is great but involves very cumbersome antenna sizes - if you want a setup that has decent performance. 80/40/20 are progressively easier to deal with and have lots of activity.
Get licensed first. They'll teach you a lot of what you need to know to operate safely and legally.
