Tired of the preprogramed junk that makes up radio? Don’t curse the DJ; seize the airwaves! An FM transmitter (like this one) is a simple device that connects to your music player and broadcasts your tunes through a weak radio signal. This signal can be picked up by receivers in the immediate vicinity, but with a few tweaks you can strengthen it and reach up to 100 feet. Although it may not be much, it can turn your car into a vehicle that doubles as a mobile radio station.
Here’s what to do:
You’ll need
• FM radio transmitter
• Putty knife
• Telescoping antenna (no more than 35 inches long)
• Soldering iron
• Copper wire
• Putty knife
• Telescoping antenna (no more than 35 inches long)
• Soldering iron
• Copper wire
Open up the transmitter
Locate the seam on the transmitter's case and pry it open with a putty knife (if your transmitter is screwed shut, you'll need a screwdriver to open it). Be careful to preserve the device's electronics. Once the transmitter is open, locate the antenna. Antennas may vary depending on the type of transmitter you are using. Sometimes the antenna looks like a small metal stick, sometimes it is a wire, but in most cases it's labeled “ANT.'
Replace the antenna
Remove the antenna and solder the telescoping antenna in its place. The new antenna might not fit in the transmitter's original casing, so make a hole for the protruding antenna, or create a new case (something like an Altoids tin should do the trick). There are plentyofcheapantennas out there that will work, just make sure that your new antenna is no more than 35 inches long. If your antenna is too long, the signal will be outside of the standard FM transmission spectrum. You want to ensure that anyone with a radio receiver can tune in.
Remove resistors
Many FM transmitters have a resistor (typically marked with an “R”) to limit the power of the signal. Since the goal of this project is to boost signal, you'll want to remove any resistors you find. By simply replacing any resistor with copper wire, you can increase the radio signal even further.
Pick your device
Next you'll want to choose a frequency on the transmitter and the device you want to broadcast from. The device you can use and what frequency the transmitter broadcasts varies from model to model, so you'll need to familiarize yourself with the built in specs beforehand. When you have this figured out, you can begin making your broadcast playlist or personal podcasts.
Test it out
Once your modified transmitter is put together it should be able to send out radio waves, but before you go live you'll want to check. Connect the transmitter to your device and turn them both on. Then tune your radio receiver to the frequency on the transmitter. If you did everything correctly, you should hear the audio that is playing on your connected device. To test the broadcast radius move your transmitter farther and farther away from your receiver, once the audio starts fading out, you have found the transmitter's limit.
Go live
Slap a bumper sticker on your ride advertising your station’s frequency. That way nearby cars will know what frequency to tune into to hear your broadcast. Soon you’ll build a grateful audience of fellow commuters suffering through that traffic jam. Nier automata gamestop. Or maybe you can tell the car tailgating you to back off.

Many people dream of owning a radio station, but making that a reality requires a lot of effort, money, and expertise. Even if you're willing and able to go the distance, there is still no guarantee of application approval for a new FM broadcast frequency by the FCC. In 2009, the Federal Communications Commission received nearly 30,000 inquiries from persons seeking to start radio broadcast stations – so you've got a lot of competition.
Get Your FM Station On the Air
Hire an attorney and a competent broadcast engineer to be a part of your team. If you want to start up a full power FM radio station, it's important to get expert guidance at the earliest stages, especially in filling out your initial FCC paperwork.
Fill out Federal Communications Commission Form 175. This form allows qualified bidders to participate in FCC auctions of available broadcast frequencies.
Fill out FCC forms 601 and 603; your initial application and license request as required by law.
Fill out Form 854 (Antenna Structure Registration).
Buy some land in the city of broadcast authorization. This is where you will place your FM transmitter. Comply with local zoning laws and obtain all applicable construction permits.
Purchase or lease an office and broadcast studio space. This can be anywhere; an office building, converted house or store front. It does not need to be in the same location as your transmitter, or even in the same city.
Hire a professional sound design firm to build your broadcast and production studios. Install new, state-of-the-art equipment and microphones to ensure crystal-clear audio quality.
Hire your staff: upper management, a program director, music director, sales manager and several salespersons, receptionist, traffic department and experienced, engaging on-air personalities.
- The FCC cannot tell you whether a frequency will be available in a particular location, or help in the preparation of applications (except for questions of a general nature).You may also want to explore other options such as Low Power FM (LPFM) licenses, which are more readily available. However, your broadcast range will be limited to only about three miles. You are still required to obtain an FCC broadcast license for LPFM stations, even at such low powers as one watt or less.Alternatively, establishing an internet-only radio station might be a good way to reach a worldwide audience while waiting for your FCC application to be approved.
- Unlicensed broadcast operation is strictly prohibited by the FCC. Fines and/or criminal prosecution may result from illegal operation of an unlicensed station.
