FM Transmitters: 87.5-108 MHz FM Senders - FM Sender...

The most powerful circuit we've seen that operates on such low voltage (just two AA cells). A range of 100 meters can be expected and, given a good antenna and FM receiver, 500 meters can be expected. An external power supply can be used up to 9 volts. Tr

Harry Lythall shares his v7b FM transmitter circuit design. The transmitter outputs 150-300 milliWatts of RF power in the 88-108 MHz band.

The Veronica 1 Watt PLL FM Transmitter is a pretty decent broadcast PLL exciter or transmitter that can be used alone or with an RF power amplifier for high power radio broadcast.

Our PCI-Max 2004 is a Stereo PCI FM Transmitter that broadcasts MP3's and steams on FM from your PC (PCI slot). It is controlled via software and will broadcast anywhere on the FM band.

Very small Hi-Fi Stereo FM Transmitter circuit that uses only 1 chip (BA-1404), and is very easy to construct. Operates from 1.5-3 Volts DC (just 1 or 2 AA batteries).

An excellent Stereo FM Transmitter which operates through the USB port of essentially any computer. FCC Compliant!

Dick Cappel's page illustrates an extremely basic small FM transmitter that rebroadcasts sounds using a 1.5 Volt battery. very simple circuit.

Simple 4-transistor transmitter electronic circuit that produces a Frequency Modulated (FM) signal at approximately 100MHz.

Schematics / circuit diagrams for a PLL 1 Watt FM radio transmitter that is enclosed in a casing. Oscillator, PLL circuits.

Circuit diagram and construction notes for a very nice 40 Watt FM Amplifier, with wide-band operational characteristics. Includes low pass filter design. Very good notes.

A powerful little circuit with surprisingly good audio quality. Can transmit up to 1/2 mile in open spaces. This is one of the most powerful FM transmitters that you can legally purchase. An electret microphone is used to add sensitivity. The circuit come

Our Dipole Antenna works on any frequency from 88-108 MHz without the need for tuning. Power handling is 300 watts.
