5W PLL FM Transmitter

Easy to build high-quality PLL FM transmitter with typical output
power of 5 W and no-tune design. The transmitter includes RDS/SCA input
and Audio/MPX input with optional pre-emphasis. It can be used with or
without stereo encoder. Tuning over the FM band is provided by two
buttons that control dual-speed PLL. The transmitter can work also
without the LCD display. Some experience with building devices of this
kind are highly recommended.
