Description. with a matching antenna, the fm transmitter circuit shown here can transmit signals up to a range of 2 kilo meters. the transistor q1 and q2 forms a classic high sensitive preamplifier stage. the audio signal to be transmitted is coupled to the base of q1 through capacitor c2. r1, r3, r4, r6, r5 and r9 are the biasing resistors for.

2 Km Fm Transmitter Detailed Working With Circuit Diagram The circuit built around transistor t1 (bf494) is a basic low power variable frequency vhf oscillator. a varicap diode circuit is included to change the frequency of the transmitter and to provide frequency modulation by audio signals. the output of the oscillator is about 50 milliwatts. transistor t2 (2n3866) forms a vhf class a power amplifier.

This long range fm transmitter using two transistors can provide reasonably good signal strength up to a distance of about 2 kilometers with a good matching 50 ohm ground plane, antenna or multi element yagi antenna. to change the frequency of the fm transmitter a varicap diode is included which provides frequency modulation by audio signals. Design of oscillator circuit: a) selection of tank circuit components – l1 and c6: we know the frequency of oscillations is given by. f = 1 (2∏√lc) here we require a frequency between 88 mhz to 100 mhz. let us select a 0.2uh inductor. this gives value of c6 to be around 12pf.

How To Make Fm Transmitter Circuit With 3 Km Range This long range fm transmitter using two transistors can provide reasonably good signal strength up to a distance of about 2 kilometers with a good matching 50 ohm ground plane, antenna or multi element yagi antenna. to change the frequency of the fm transmitter a varicap diode is included which provides frequency modulation by audio signals. Design of oscillator circuit: a) selection of tank circuit components – l1 and c6: we know the frequency of oscillations is given by. f = 1 (2∏√lc) here we require a frequency between 88 mhz to 100 mhz. let us select a 0.2uh inductor. this gives value of c6 to be around 12pf. Step 1: things you must know about fm transmitter circuit. transmitter: the transmitter is an extremely important device, its purpose is to produce radio frequency waves for transmission into space. the important elements of transmitters are as follows: microphone: a microphone is a device that converts sound waves into electrical waves. Long range fm transmitter. april 4, 2020. in this project, let’s learn how to make a simple “long range fm transmitter” at a low cost using minimal components. as you can see in the diagram, the circuit is simple, easy to build and test. let’s begin to build our long range fm transmitter.
