Links for transmitters
List compiled by Free 103 Point 9

Veronica makes the best transmitters, if you want to spend money on a pre-built transmitter that works perfectly.

Broadcast Warehouse has good transmitters. Best buy is a 1-watt with only minimal soldering that anyone can do.

Free Radio Berkeley's Stephen Dunifer leads the microradio movement, and makes good transmitters.

Tampa, Florida pirate makes good custom-built transmitters.

Ramsey makes the cheapest do-it-yourself kits.

Also, check Ebay often, many transmitters are available there.

Great, but where can I buy the $20 transmitters that the Wired article alluded to? As of today, all the links lead to expensive units!

I too would like to get into this, but I'm not into soldering. Is there an FAQ or something to get me just up and running quickly?

That's not exactly $20 - $44.90 including power supply.

Sorry that we didn't post this info.  The assembled kits that we are using can be found at http://www.canakit.com

When you go to the site click on CATALOGUE, then click on FM transmitters.  The model that we used is UK108.

Be Warned : This is the base model. In the transmitter world, you are getting what you paid for.  A $20 transmitter will broadcast around a block radius in good conditions, from one end of the room to another in bad conditions.

If you know what you want to broadcast, that will shape what you want to buy.  If you know you want to broadcast music, but don't want to talk there are radios specific to that. The model that we used has a manual tuner.  If you pay a little bit more you can get a digital tuner.

We are learning as we go, so the best advice would come from the manufacturers themselves. Before ordering a radio transmitter on-line, call Canakit directly at 1 (888) 540 KITS

This is probably off-topic but I use a mini FM transmitter I bought at Best Buy. It's purpose is you put a portable/walkman CD player in your car, hook it up to the transmitter and then you listen on your car FM radio. Thats not what I use it for though. I have it hooked up to my computer in the basement then broadcast audio through my house and listen on a walkman. I can listen to streaming audio from the internet, music cd's in the computer, or a shortwave radio hooked up to the audio in jack of my soundcard.

The range of this thing really is bad and not appropriate for this project, but you can increase the range by adding a wire to the antenna.  I have been thinking of jacking up the voltage to the thing to see if I can increase the range. It runs off one AA battery.  I can hear the thing throughout my house and in the yard. It turns out that most car radios are pretty powerful receivers and when in my car I can hear it about 3 houses away.  I live next to crosstown freeway and you can hear it when you drive by my house. If nobody in my neighborhood puts up a transmitter for this project I will change the freq just to join the party.

This has been on my mind for years. Now think synchronized cds or streaming radios on the same broadcasts. Creating art with them as discussed in the article is expressly novel sounding to me and hundreds of units spread around a town disgused as everyday items would completely baffle the system. As far as talking to yourself all the time I would guess all transmissions everywhere are most likely recorded in some massive keyword filtered unaccessable by the public database and deposited in a file that deserves to be baffled. Think reflectors. Just do it, this will help, every little bit helps, fill the airwaves, claim them, they may not be owned and used to control and enslave. This is empowering, be inspired and free yourself. Please use this art form to spread love, show respect for all individuals as equals, and encourage celebration of life and freedom of expression.

To be sure this is on topic...some kind of kits should be availiable at your local electronic store or radio shack. How about using an old dc power cord with some resistors as a power supply? A soldering gun in every home. It gets better by the minute.

How about a station of looped laughter in every town? Or move up to television transmitters and broadcast funny faces all day?

Loving It, Thank YOU

I find it really hard to read the text from 'radiorevolt' that has the busy diagonal
background behind it.

I appoligize in advance for the shameless commercial pitch, but we (www.neurosaudio.com) sell an open source digital audio player that has IMHO the best legal digitally tuned FM Broadcaster in the business.  Although not really marketed for this purpose, and not the cheapest solution, it can also be used to transmit from any source.  It would be a no hassle way to accomplish what you're looking to do.

If there's interest, we could make a unit with a small amount of memory for $50.  Currently our base model costs $100.  It includes a complete solution for broadcasting though, so you could just put your audio on it and broadcast from anywhere with a pocket sized device.  Further the firmware is open source, so it's open to user modification.

My friend has a Ramsey transmitter for streaming audio from web. He uses it all baseball season. He says it works reasonably enough to listen to Yankee games live while out on the deck, in the shower(big house). The units fer 20 bucks, I still didn't see,(I saw one fer 25 bucks, USD). The Ramsey kits are easiy enough to build and if you put the transmitter at a good height, say in the attic, and run the audio wires up there, you could (on the am band) do a solid half / full mile. FM is line of sight and would be less, I believe.

But the kits aer worth the money, also see what the voltage is, but nicads and a charger. a tad cheaper and portable.

I have tried the UK222  from http://www.canakit.com.  It is about $35 but transmitts the sound in pretty much much around my whole home including the yard.  The only noticable issue is that in the first few minutes of turning the device on, the frequency may drift slightly because of the heat so you may have to retune it depending on the location but in my IMHO, it is worth the 35 bucks.

A small caveat about kits:

I bought the cheap Ramsey transmitter, built it, but could not get it to work properly. The signal was very faint (very low volume) from even a foot away from a receiver. I took it down to a friendly electronics shop. The guys there messed with it for 15 minutes and couldn't get it to work better. Then they looked at my soldering and said it was sub-standard and I should resolder the questionable looking ones. I took it home and did that, but no improvement. I'm embarrassed to go there again, so I ended up with something that doesn't work. I should add that I have a low level ham license and I've soldered electronic things before -- I'm just not a pro at it.

At the time, I got it for the purpose of  broadcasting music from my computer around the house, but what got me thinking about it in the first place was when Pacifica (KPFA for me) was in danger of losing it's station, I thought maybe strategic points could be set up where one would download the signal from the web and rebroadcast to neighbors. They settled their problems, but, seeing your site today after coming across it somewhat randomly, makes me think of that again.

Another entry in the not-quite-so cheap category is from C. Crane Co.


Which is a small FM transmitter which runs on either two AAs or an AC adapter, and has an eighth-inch stereo plug for input. Out of the box, I was underwhelemed by its range - though the fact that it will allow you to boradcast on any frequency is nice, with a digital display at that. However, they thoughtfully designed it with a trim pot on the circuit board that significantly increases its output:


This makes it much more fun...

Why don't we do a re-volt re-lay? Forget about making antennas bigger or transmitters more powerful or otherwise boosting the signal; that just makes trouble. Why not instead just link transmitters and receivers together to cover a broader (or longer) area...?

I have a transmitter from www.edmdesign.com and it works very well. The 10mW unit gives good coverage.

A good source for higher powered AM/FM transmitters.


I bought a 10 watt AM broadcast transmitter from them and love it. Easy 5 mile range. They have FM transmitters, 5-15 watts and beyond. They are really inexpensive and sell to anyone.

I am actually using a Belkin Tunecast II, which has an LCD frequency selector. Replacing the antenna wire really makes a big difference, I am using a full-wavelength wire, and get about 50ft coverage indoors. These are about $19 including shipping on EBay, and highly recommended.
