Radio Re-Volt: Broadcasting For The Common Man
An anonymous reader writes "Well, almost for the common man. This Wired article describes a project of the Walker Art Museum in Minneapolis to teach people about the power of radio through the use of cheap low-power FM transmitters. Although each transmitter is limited to a range of about a block, they're cheap enough that I could see them being spread out across a city to cover it with a signal. It'd be interesting to do something like that and feed these inexpensive networks via a netcast. You could use something like this to air programming that commercial stations won't broadcast because it's not commercially viable or because it doesn't fit in with the interests of big media. You can read the above article or go directly to the Radio Re-Volt Web site."
"Radio Blogs"...I should probably be scared, yet somehow I'm fascinated!
Down With Slashdot BETA!!! I've been around the corner and seen the oliphant; you can only abuse me from your perspecti
Of course, such small radio stations will not recover the First Amendment -- the Internet has done a lot more to recover First Amendment rights anyway.
However, even with one person one watt, the failure of the government to protect freedom of religion and indeed impose politically correct beliefs upon the private lives of citizens continues not only unabated but exacerbated through the multiplication of government agencies overseeing out compliance with federal mandates about with whom we must associate in our private affairs.
The damage caused by that interference has now built up a debt as large as slavery. Such debts are so enormous and the government so unlikely to pay down those debts that basically the current US government cannot claim any legitimacy any longer.
Seastead this.
Or as a micro station at outdoor festivals, concerts and sporting events to name a few. If you have ever been to Grass Roots, Jazz Fest, or a phish anything, you could see how this could be viral and allow for some interesting intermissions.
Who are you? The new #2 Who is #1? You are #617565. I am not a number, I am a free man! Muhahaha.
Of course I like the idea of the classic 80s pirate radiosenders but today you can just broadcast whatever you want via the net and make it available to a much larger audience. I really like those for iTrip like applications, though.
That culture and new ideas can come from "that place you fly over on a SFO-JFK flight."

RHZ radio is already up and running and streaming content on the internet so that remote stations can rebroadcast it. Very cool stuff!
Signatures are a waste of bandwi (buffering...)
And I think you do need a license to operate a CB radio.
No you don't.
Citizens Band (CB) Radio Service is a private two-way voice communication service for use in personal and business activities of the general public. Its communications range is from one to five miles.
Licensing
License documents are neither needed nor issued and there are no age or citizenship requirements. As long as you use only an unmodified FCC certificated CB unit, you are provided authority to operate a CB unit in places where the FCC regulates radio communications.
How does it work out buffering and syncing? How does it avoid "ghosts" or echos in the broadcast when a radio is simulateously received broadcasts from two base stations broadcasting the same broadcast on the same frequency, one getting the source broadcast over a DSL line with some latency, the other over fibre with much less latency?
I expect that is something that must be solved in software, and, according to the article, this is a hardware device. The original poster's dream of a blanket grass-roots radio station is a little far away. That being said, a small FM broadcaster would be great for broadcasting something in the house and being able to tune in from any simple FM radio around the yard.
The significant problems we face cannot be solved by the same level of thinking that created them. -Einstein
I don't like the idea of more EM radiation flying around. What kind of hazard would all these broadcasts be to people's health? Is it worth even thinking about?
Switching from an aluminium foil hat to tinfoil should be adequate for a one watt FM transmitter.
And whenever someone walks near you with a cell phone? They're trying to hack your brain.
This would work better with Wi-Fi enabled boom boxes. Wi-Fi can handle multiple transmitters. An Wi-Fi enable Walkman-like device has real possibilities.

There's a product along these lines I've been interested in checking out.
It's called the "MP-308 Car USB / FM Transmitter", Here's a review of it.
Strangely enough, it seems to be the only Car MP3 player out there that takes a USB card - the discontinued "EMPEG" used to have such an input, but it's hard to get now. I've been wanting to use a nice cheap USB stick instead of CDs for the sheer convenience of popping it into the car and listening with an interface that's much more casual than CDs. Instead of plugging into the car's existing audio system, it works by sending out a short-range FM signal across the 87.7-88.7 dial (you select which subrange). That makes setup easy (so long as you have a good radio in the car), but I can't help but wonder how many radio markets have that FM signal open at that range, and what interference this would have with nearby cars. Fortunately, the device is fairly cheap to experiment with - you can find it for around $50 on pricewatch.

I think this is a really interesting comment. But doesn't Lawrence Lessig (who thinks a lot about electronics and free speech) write that private interests pose at least as large if not larger threat to free speech rights on the internet?
Maybe low power radio will make a comeback in part because of commercialization of the internet? That is, low-power broadcasts represent an affordable, noncommercial space for creative experimentation and communication within a community (a/k/a free speech)?
The homebrew quality of the transmitter also recalls early descriptions of the personal computer kit-builders in the 70s, also a good time for free speech fans.
The small scale of the communities recalls Linus Torvalds posting about his Minix-alternative project.
Its fun stuff. What's not to like?
I'm laughing at clouds.
What so many people are missing about the importance of this idea is that the mass media has created a world for us. Big Money used the media to convince Americans that lower taxes for the rich and lower trade barriers and tariffs were going to be good for Americans. Those ideas were found laughable by most Americans 40 years ago. But when the billionaires and corporations fund think tanks and foundations with billions of dollars, funding and developing rightwing talent, they were able to convince Americans to hold beliefs that were actually detrimental to their own well being.
THat is why this kind of grassroots media is so important.

I'd be interested in browsing through their site but the diagonal green and white lines over the text makes reading a chore rather than a pleasure. Looks like a sample from the Bad Interface Hall of Shame.
Microwatt transmitters have their uses, but I'm afraid that ain't one of them.
So... what's the point? Do people even listen to the radio anymore? I mean, maybe in their cars - but anywhere else? I've been involved in one way or another with radio since I was a teen and even operated my own fleawatt when I was a kid, but that was a long time before the internet.
If you want to be a pirate it seems to me you'd reach a lot more people taking the max headroom route. When I was a kid I actually wanted to be a radio pirate - now I see no point in it at all aside from being any easy means of civil disobedience. But now, with the internet and the ease with which we can build a vast video library (not to mention it's just as easy to locate a tv modulator as an fm modulator) I'd much rather be Reg.
CB radio consists of 40 different channels anyone can use.
Let me tell those of you who have not used a CB radio before, they are incredibly handy to have. I have a good setup on my car (although my transceiver just took a dive, will be upgrading that unit this next week!), and on the open highway in open country, you can send and receive a good distance.
A CB radio is the best "radar detector" money can buy. Truckers are always on the lookout for speed traps, and will continually call out the position of law enforcement officials, whether they're stationary or on the move.
Having a CB radio when you're traveling to places you've never been is also a godsend if there's some kind of detour, and you don't know your way around the area. Call out for directions, and a local driver will usually help you out.
CB radios are also nice in an emergency. There are decent people out there who will help someone when they're on the side of the road, and need help. At the very least, someone will be able to relay the message to law enforcement, or a tow truck or garage in the area.
Probably the best thing CBs are good for is helping one stay awake while on a long drive. It's always nice to be able to chat with someone to help you stay awake. Usually there's someone else looking for exactly the same thing.
CBs are a lot of fun, but keep in mind they are public channels. There are a lot of individuals who use incredibly foul language, and some truckers despise people in "four-wheelers", so you won't always get an answer to your questions. Be polite, though, and you'll find someone willing to chat or help out.
It just don't work the way the OP "imagined" it. This isn't digital, it's not a "software" problem.
1984. The height of communism in at least one Eastern European country. We were teenagers, and very much into AC/DC, Judas Pries, and ever'thing western. One of us knew some electronics; so we got ourselves some parts and soldered together some FM transmitters. Then we broadcasted AC/DC, other heavy metal rock, stupid teenager rants :), and sometimes even Radio Free Europe. All this at random times all around the neighbourhood, so we don't get caught. Those in the know realize how much the secret service hated people like me and my friends (and they really hated AC/DC). And we knew that is was dangerous to taunt them. Nevertheless, it was fun.
Present: people probably realize how powerful it is to be able to disseminate ideas, even in a limited and local setting. And this type of radio TX is all but forgotten in these day of the web, but it can be much more personalizable. People react different to hearing a real voice for a change. I'm glad to see people pushing the idea of microradio. In fact they should make radio TX free, not hand guns.

From http://pittsburgh.indymedia.org
" Two community radio stations, one in Knoxville, TN and the second in Santa Cruz, CA have been raided in the last 2 weeks by armed US Marshalls (and/or FBI) and the FCC. Last October, San Francisco Police and the FCC raided a popular Bay Area radio station. Despite the federal government's war on community media, radio activists across the US are operating community stations in open defiance of FCC regulations. The FCC strives to squelch community radio so that the airwaves remain free for media conglomerates like right-wing ClearChannel Communications, which owns 1,250 radio stations (six in Pittsburgh), and Viacom-owned Infinty Broadcasting, which owns 180 stations (four in Pittsburgh).
Also, in Pittsburgh, two broadcasters were shut down in the past week due to FCC intimidation. South Side Radio broadcasting at very low power on 102.9FM, and "WCSA Radio" in Plum, PA (Allegheny County, east of Pittsburgh near Oakmont). Indymedia Rustbelt Radio, our biweekly news program on (licensed) WRCT 88.3FM, will feature reports on these actions in Pittsburgh and around the US this week on Tuesday, October 5th at 6pm.
Next week the National Association of Broadcasters, a powerful lobby group, will meet in San Diego. In opposition to their corporate agenda, independent media activists will be holding a four day convergence of workshops, speakers, and actions to tell the NAB "We Want Our Airwaves Back!"."

One could use icecast and reach globally - given one has the bandwidth to do so. On a normal DSL connection, however, you're limited to < 1MBit upstream. So, you could have (at most) about 8 people worldwide listening to your broadcast. THEN you have to worry about licensing fees if you're really thinking about setting anything viable up. I help operate at a 13-watt radio station at the University I work at. We are pretty popular in the radius of a few miles that we reach. Last year we added a Shoutcast stream that has proven pretty popular, but we had to limit the quality to 24k and the number of listeners so we wouldn't saturate the University's outgoing pipe. Bandwidth alone, we pay about $800/yr in licensing to ASCAP, BMI, SESAC, and SoundExchange for over-the-air and streaming rights. We're lucky, as an University, our streaming is often including in our over-the-air license and we don't have to pay per song played either. My point. Streaming is great, but there are still a number of hurdles to jump.
You do need a license for aviation and some marine operation though. (The rules for marine operation are pretty strict -- license required for boats over a certain size and ship-to-shore operation, as well as HF radiotelephone. I don't know the specifics on aviation.)
Coordinating with other 'micro broadcasters' so that you blanket a city, might pose a legal problem.. Since the intent was for you to have limited coverage of your content..
.. I would bet there is something in there to account for such an idea.
No, I don't have the law handy, but

If you are going to try something like this, Ramsey electronics has a MUCH better quality transmitter. It broadcasts in stereo, not mono, and is crystal controlled, so it wont drift in frequency and need to be tuned like they recommend in the article. The maximum output is right at the legal limit of 1/10th of a watt.
? pa ge=amfm
They also have compressor/limiters that make the audio sound louder (STC1C).
http://www.ramseyelectronics.com/hk/default.asp
I personally have the FM25 (predecessor to the 25B) - the audio quality is comparable to commercial stations - $119 in kit form. Assemble it, plug the line/speaker output of your computer into it, start winamp/itunes in shuffle play, and you are on the air. (and no, I don't work for them)
I live in Minneapolis and am pretty sure that this project will have absolutly no effect on the population at large. I see it as an "art project" done by the Walker ART center. The majority of these transmitters will be used for a brief time and shelved. The participants in the project will feel that they have learned something about radio and will have shared a common experience and that's about it.
Commercial and to a lesser extent public radio in the Twin Cities is pretty big thing. We have a couple of "giants in the industry" here with two AM stations that are historic giants of the industry (WCCO-AM and KSTP-AM) both 50,000 watt clear channel stations and an FM station that consistantly captures the highest market share of any station in the country (KQRS-FM). On top of these giants, there are many other stations on both the AM and FM bands that cater to nearly every taste imagineable. Our airwaves are crowded.
Over the years we have had our share of pirate and "underground" stations. Most of them have gone off of the air before I even heard them - but the several that I did get a chance to hear reminded me more of "Bob and Ted's Excellent Adventure" than anything else. Nothing special at all.
I do believe that there is a major problem with public airwaves here and probably in most every major market. The stations are locked into playing the same old stuff. I really do think that stations should be required to devote a portion of their broadcast time to programming local and new talent. They are too locked into the charts, the major music labels and other things that sort of homoginize and blend the music into pablum for the masses.
There is a whole lot wrong with radio but a bunch of low power transmitters aren't going to do anything to fix it.
There are certain parts of the bandwidth which are "off limits" to everyone, public or private.
Take a look here for some of the frequencies.
The idea is that, if we want to take clear radio-frequency "images" of distant images, it makes sense to avoid polluting the sections of the bandwidth where those images are to be found. No, I don't think any of these lower-power trasmitters will be broadcasting directly in these ranges. Unfortunately, most transmitters also transmit harmonics of their main frequency, at lower power. Consequently, everyone gives these frequencies, AND their lower harmonics, a pretty wide berth.

Yes. You're right. I believe in the equal right of any people to separate from others as declared in the first paragraph of the Declaration of Independence. It overrides what any Men may put down on paper.
Indeed the entire point of the First Amendment to the US Constitution was to minimize the need for war against or between governmental entities by allowing people to peaceably separate from one another to the greatest extent possible within the laboratory of the States. The founders understood scientific method -- and the need for control groups to discover what works and what doesn't work in social experiments, involving beliefs about how we should live our lives, as well as physical experimentation. If you cannot allow people to voluntarily enter into their own experiments and impose upon them your perverse ideas of what constitutes "equality" then you have just declared war on the Declaration of Independence and on freedom itself.
That they had been corrupted by slavery in no way detracts from the importance of their overall vision.
Seastead this.
It has everything to do with it only almost 70 years too late. The Telecommunications Act of 1934, by recentralizing control of disemination of ideas under the new technologies of broadcast, undid the Guttenberg revolution. The Guttenberg revolution was the undoing of the theocratic control of Europe which was maintained largely through monopoly on the disemination of ideas through the written word. It was the theocracy of the pre-Reformation era that controled the armies of monks who scribed the books and handed them out to the priesthood to interpret for their "flocks".
You are simply a new form of "sheep" indoctrinated by the new theocracy that has grown up in the centralization of media.
Seastead this.
