BA1404 FM Stereo Transmitter With Amplifier

This is a classic low-cost stereo FM transmitter that can send your signal to a FM receiver within 500 meter range. This transmitter uses the famous BA1404 all-in-one chip and operates from 5v power supply. Stereo channel separation is excellent. You can even use this as a front-end stereo RF signal generator for a large FM transmitter setup; by adding step-by-step RF amplifier. A few inch long copper wire can be soldered at the PCB to use as an antenna. The gang-condenser can be used to adjust frequency output. You can use this with your iPod or other audio source, inside your home or car on in an outdoor garden party or wherever you use.
