Make FM Transmitter (Super Simple)

This 300W RF power amplifier for your fm transmitter has 2 x TP9383 transistors. 300W radio power amplifier for 88 - 108 MHz band. 300W RF power amplifier

18W FM Transmitter Here's FM transmitter for commercial FM band that provides 18 watts of power. Since the electronic diagram is too large we decided to...

This small power FM transmitter can transmit more than 1 km in good conditions. The modulation can be made so much with a microphone or audio source. Circuit of power fm transmitter is built around 2n2218 transistor. Transmitter coil is 5 turns of enameled 22 AWG wire, with diameter of 1 cm without nucleus. Look at the capacitors that it should be ceramic. The antenna should possess from 15 to 40 cm. For transmission it ties a receiver of FM (radio) in the proximity to half volume in a free…

Here's a simple VHF FM transmitter that could be used to play audio files from an MP3 player or computer on a standard VHF FM radio. ...

This Three-Stage FM Transmitter has an RF stage in its yield to balance the amplified signal. By utilizing a reasonable antenna

The following is a simple yet powerful 4W FM transmitter which is tunable to 88-108MHz frequency. Connect to your ipod/computer, etc. When this was first made, I only had a 2N2219A on hand, which resulted in a lower RF output. I have since swapped out the transistor for a 2N3866 for full 4W output at around 15VDC supply. In order to achieve a high output level, you will need a well tuned antenna, and a large heatsink to dissipate the heat from T2 transistor. Transmitter was mounted in metal…

Here is the electronic components list with images. To build a circuit with them, we must first know their purpose, shape, and values.

The circuit presented here uses a crystal oscillator and frequency multiplier to generate a highly-stable carrier signal frequency of 96MHz. It can be used to transmit voice or music up to hundred meters. The circuit is built around 9018 transistor, 24MHz crystal, air coil and a few other basic components.

FM Radio Transmitter Solder Project Kit with Audio Lavalier Microphone Soldering DIY Kit for Electronics Practicing Learning, 87-108MHz

This is a 1 Watt PLL FM broadcast transmitter. The RF output varies from 500mW to about 1.2W depending on the frequency selected and RF output transistor used. Motorola 2N4427 always seems to work well. Transmitter uses CMOS PLL VCO that prevents the frequency drifts. The frequency is selected via DIP switches. The transmitter is supplied by 12V DC and can also be powered from the battery.

In frequency modulation, the data is transferred by varying the frequency of carrier waves. Also, there are different ways to make
