Build a low power FM transmitter kit in under an hour or two. FM transmitters in a kit form are relatively easy (basic soldering skills) to assemble and inexpensive (many are available for under $20). Low power FM transmitters require no license to operate (in the U.S.) and provide clear, static free signals and choice of either mono or stereo transmission. | Build a low power FM transmitter kit in under an hour or two.

# Determine need. A popular use for these devices is to transmit audio from a portable MP3 player or internet radio station on a computer to a radio or stereo located in another room or even outdoors. Some choices are: Mono or Stereo? How powerful (size of area to cover)? How many inputs (microphone and / or aux)? What kind of power source (battery or AC adapter)? These are just a few of the questions to be answered to obtain the correct transmitter for the application desired. | # Determine need.

# Build. Set aside at least the amount of time recommended in the kit directions to perform the assembly and soldering. Allow more time if this is the first time building a kit or using soldering iron. Lay out components and tools on a clean heat resistant surface. Assemble kit as outlined in directions. | # Build.
