Make FM Radio Transmitter For Music

Yet another FM transmitter! If you are looking for a simple, but good FM transmitter for your music player, then give this circuit a try. Simply plug in your music player/computer using a phono plug, and broadcast music/audio throughout your home. Stability is good, good range, and audio quality is very good. The circuit is very simple as well. If you desire a more complex crystal controlled circuit, then visit the link below. I also have another video which has a very stable FM loop antenna which can be converted from microphone, to accept a phono plug. Be sure to choose a frequency that is not used at your location. Once the circuit is complete, power up the transmitter with the audio source attached and volume about 1/3 of the way up on the music player/computer, then scan through the FM band on your radio to find the frequency you are transmitting on. To raise the frequency (make the coil wider/stretch it slightly or remove a turn from the coil), to lower the frequency(squeeze the coil slightly or add a turn to the coil). Frequency can also be raised and lowered with the 4-40 cap if you used a trimmer cap instead of a fixed value.

Thanks For Watching!
