Anonymous' Airchat Aim: Communication Without Need For Phone Or Internet
concertina226 (2447056) writes "Online hacktivist collective Anonymous has announced that it is working on a new tool called Airchat which could allow people to communicate without the need for a phone or an internet connection — using radio waves instead. Anonymous, the amorphous group best known for attacking high profile targets like Sony and the CIA in recent years, said on the project's Github page: 'Airchat is a free communication tool [that] doesn't need internet infrastructure [or] a cell phone network. Instead it relies on any available radio link or device capable of transmitting audio.' Despite the Airchat system being highly involved and too complex for most people in its current form, Anonymous says it has so far used it to play interactive chess games with people at 180 miles away; share pictures and even established encrypted low bandwidth digital voice chats. In order to get Airchat to work, you will need to have a handheld radio transceiver, a laptop running either Windows, Mac OS X or Linux, and be able to install and run several pieces of complex software." And to cleanse yourself of the ads with autoplaying sound, you can visit the GitHub page itself.
They're anonymous, so they don't need to respect your frequency assignments.
This is almost certainly illegal in the UK. Encrypyted comms over citizen/public radio bands is not allowed. Steganography would be required to carry an encrypted payload without being caught, but you'd still be breaking the law.
10-4, good buddy!
Hmmmm... might have to dig out my 150W linear amplifier I used to use to drown out obnoxious truckers with, when they needed a smackdown.
Packet radio is done every single day on HF on up. With APRS, you can get messages from one coast to the other and back again without any internet or phone connection.
If you DO have an Internet connection, http://www.aprs.fi/ even shows you where all of the beacons, digipeaters, and stations are at a given time, and allows you to see all of the packets that are sent.
It's a great idea, I'll accept that, it's also not new - this has existed in some commercial form one way or the other (various calculators could communicate images & chat freely via the airwaves, Nintendo DS could also seek players within a certain range to do some picto-chatting or game with each other). Radio Amateurs have done this since the 80s, me too... I did it with a Commodore 64 + a home made 1-transistor modem and a walkie talkie, worked like a charm, but hey...it's good to see the kids of today doing something else than chatting on the internet.
1). You may want to check with the laws of your country, transmitting on most bands are illegal and could potentially disturb or disrupt ambulance communication, police or other important communications. Becoming a licensed Radio Amateur the legal way, is a good step in the right direction.
2). There are existing options you can use to chat & send files via radio today, Ham Radio enthusiasts knows all about this, visit your local (ARRL or equal ham-radio club in your neck of the woods).
3). If you want to chat worldwide, you could get a shortwave radio - or satellite antenna with the appropriate transceiver and a packet modem, with this - you can chat digitally, send pictures, send files as long as you have a radio amateur license to do so. Basically you need this to operate on the bands, in most countries you can listen in on radio amateurs communicating via packet-radio without a license, but you DO NEED A LICENSE TO TRANSMIT.
There are many more things you can do, there are a lot of commercially available radios, digital radios and much more. And none of them require the internet.
What this world is coming to - is for you and me to decide.
I'm sure they're probably using Baofengs like everyone else who likes to freeband.
Armature Extra here, how can I help you get licensed? It's not that hard and these days you don't even need to learn Morse code like I had too. Entry level license requires only basic understanding of Ohms Law and Power calculations, a little about RF safety and some basic things about the rules (like what privileges your license gives you, who the FCC and ITU are.)
Great hobby with lots of interesting things to look at. We do community service like weather spotting for the NWS, event and emergency communications. Don't like talking on the radio? There are lots of computer based things to play with, Digital modes like PSK, packet or HSMM stuff. We have software defined radios you can build and program too. I'll bet we can find something of interest for you to play with.
Don't like taking tests? Well, what if I told you all the questions and the correct answers are published in advance and the test is multiple choice. 35 questions are asked and you only need 26 right. You can practice online (usually for free) and know almost for sure if you will pass or not before taking the test. Tests are likely given regularly and very close to you, no matter where you live and cost $15 for as many as you can take and pass. Pass all three to get your Extra and enjoy the full set of Armature privileges available. If you pass, your license will be good for life as long as you keep requesting renewal every 10 years (renewals are currently free if you file yourself online).
Go ahead.. Take a look!

I thought they were best known for making grandiose claims that never came to fruition? Remember how they were going to destroy facebook?
I thought they'd done that? They logged on to Facebook, decided it was already rubbish and left it as-is. Job done.

Most posters here seem not to have read the details on the Github page, and are missing the point.
This is a way to have encrypted point-to-point communication or (in some cases) network using any radio (or other) transmission equipment that will transmit/receive audio signals and allow you to tap-into the analog audio circuit of the transmitter and receiver. You could use it with:
- telephones (landline kind)
- mobile phones
- radio transceivers (legal or illegal - the protocol doesn't *require* that you break the law!)
- optical communication equipment - free air/fibre
- etc. etc. etc.
It just defines a common protocol and means of modulation/demodulation.
They take a whole lot of words to say this, and throw in a lot of revolutionary rhetoric.
And yes, it's very similar to amateur packet radio, except encrypted. So, lots of existing code to draw from.
It's well within the capability of any PC or smartphone today. Although I let my ham license lapse many years ago, I do have a couple of receivers squirreled away somewhere, and a few years ago I experimented with listening-in on amateur packet radio. You just run the output from your receiver into the input of a Soundblaster card (I SAID this was a few years ago...) and the application handles the decoding.
An interesting side-note: If you're near an airport, you can use similar software to decode VHF ACARS transmissions. (The kind that hasn't helped much in locating MH370). Just install some open-source software, hook your scanner up to your PC, tune to the right frequency, and it turns the squawks into somewhat-readable messages.
It's biggest drawback is it's biggest strength, IMO. It DOESN'T define a common frequency, some complex frequency-hopping or spread-spectrum scheme, or even common transmission media. It would be extremely hard for it to gain critical mass. On the other hand, it means there are an awful lot of places one would have to look to find it. It's up to whatever group that wants to communicate to settle on a transmission media and (if applicable) frequency.
The thing is though? The truth is typically someplace roughly in the middle.... EG. In Bundy's case, the truth is somewhere between his idea that federal land ownership is "unjust", and the idea that federal govt. should buy up huge swaths of land and just sit on them (for over 100 years at a time, in this instance, and probably many others) -- and then selectively enforce rules with an iron fist, when they suddenly deem it worthwhile.
So the "anarchy" brings attention to the initial problem, and *hopefully* brings about an end result of some modification to existing regulations, to improve things in the future for everyone.
It's pretty well documented in historical records that when the United States fought for freedom from England and the Revolutionary War began, there was a lot of this "over the top" behavior involved too. British soldiers, ordered to simply stand guard in certain areas, were spit on, had beer bottles thrown at them from nearby taverns, etc. -- in an attempt to provoke one of them to give in and fire a weapon. Bottom line? You can't really create effective change if you just sit quietly by and follow all the rules. The protesting/anarchy isn't usually 100% right, but it serves as a catalyst for change.
