If you are good at soldering, then you will be able to build this stereo FM transmitter for your personal radio station or any other hobby use.
It uses 51 series micro-controller and a dot-matrix LCD display, This will show you frequency, output power and other relevant information on screen.
After building and testing this, enclose it inside a beautiful metal enclosure and mount the heat-sink at the enclosure body.
Add a 50 ohm antenna, 12v stable power supply (we recommend lead-acid type battery, it draws maximum 3 ampere current at full power) and a stereo audio source and you are done.
It has as high as 63dB stereo separation, so your music will hear crisp on a similar high quality FM receiver. We have seen the quality of this little baby is at par with any broadcast station.
You can adjust the output RF power from 0.5W to 7W within the entire 76MHz to 108MHz broadcast spectrum.
