Combining a podcast with a low power fm transmitter is a great way to reach your local community. It may not be legal to do this, so you should check on the regulations present in your area. Usually, these transmitters are short enough in range that they would not trigger any legal hassles, but be on the safe side.


Basically, what you will do is this:

  1. Make a podcast of information, news, interviews, music or whatever
  2. Get a cheap mp3 player, cd rw or some other media player
  3. Put the program you created on repeat
  4. Plug it into the transmitter you made
  5. Transmit to your community, or your house for that matter
  6. Then any radio inside your range will be able to pick up your program.
  7. Pay attention to what your community is interested in hearing and create programming for them.
  8. When you want to make a new edition of your program, make a new one and repeat the steps above



Here are some links to radio transmitter circuits:

Kit from Jameco, kind of pricey, and a little fussy to build - Jameco Transmitter -

This one looks like it is pretty straightforward, not too many exotic chips - Netsciencenews Transmitter


Schematics and instructions, circuit board trace isn't on the main page - http://sound.westhost.com/project54.htm


Good laundry list, image of the foil trace for the board could use some cleanup. lots of comments - http://www.aaroncake.net/circuits/fmtrans.asp


The variable capacitor is the only exotic component in this one - http://www.uoguelph.ca/~antoon/circ/fmt1.htm


Samantha used this circuit board trace to make her transmitter - http://www.chaneyelectronics.com/products/radio/c6715.htm

This one has what may be the most forgiving design ever. It needs a special order variable capacitor and the transistor is a bit unusual - http://broadcastyourpodcast.com/
