This is an 8W stereo FM transmitter with PLL TSA5511 synthesizer. Device is controlled by PIC16F84 microcontroller which can adjust frequency from 88 to 108MHz with 0.05MHz steps.

Frequency is displayed on single line LCD screen. Current design was able to reach about 10km distance. But such power could do better with better antenna. Microcontroller hex file.
