PLL FM Transmitter with PIC-Based Tuning
This easy to build PLL FM transmitter can deliver RF power output typically of 5 Watt. The project uses PIC16F627A to control PLL IC TSA5511 during FM Tuning process. PLL in-lock state status is displayed on LCD or you can check it on LED indicator (when LCD not connected).
The transmitter can be used with or without stereo encoder. This Pira’s project includes RDS/SCA input and Audio/MPX input with optional preemphasis.
