This page contains information about the popular FM transmitters that are used at DIYC.
General Information
What is an FM Transmitter?
An FM transmitter is generally a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system but can also be a stationary device that plugs into the headphone or line out jack of a computer. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
Why would I want an FM Transmitter?
Many DIYC'ers sequence their shows to music. This allows people who stop and watch the blinky/flashy to enjoy the music as well. Vixen supports sequencing to music.
How do I choose a frequency?
Visit this website:

Enter your zip code and click go. The page will return a list of vacant channels. Choose one, and tune to it to make sure it is vacant! Now you have your frequency to build your antenna.

Antenna Designs
A great companion to a low-power FM transmitter is an efficient antenna. Many DIY'ers have built dipole antennas because they're inexpensive and very efficient. For information on how to build one, click here: How to make a dipole antenna.
