Build a 1W Long Range FM Transmitter Wiring diagram Schematic
How to Build a 1W Long Range FM Transmitter Circuit Diagram. This is a simple1W Long Range FM Transmitter Circuit Diagram. This is a long range, very stable, harmonic free, FM transmitter schema which can be used for FM frequencies between 88 and 108 MHz. With good antenna transmitter can cover 5km range.
1W Long Range FM Transmitter Circuit Diagram
It has a very stable oscillator because it uses LM7809 voltage regulator which is a 9V stabilized power supply for T1 transistor. Frequency adjustment is achieved by using the 10K linear potentiometer. The output power of this long range RF transmitter is around 1W but can be higher if you use transistors like KT920A, BLX65, BLY81, 2N3553, 2SC1970 or 2SC1971.
