Tutorials: On Radio Transmitter

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

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

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.

Circuit diagram for an AM radio antenna preamplifier that amplifiers the signal before it get to the AM receiver, thus making the AM radio signals stronger for better reception.

The TX5 from Broadcast Warehouse is an extremely high quality stereo FM transmitter that complies with FCC Standards, meaning that it can be used for commerical broadcasting. Output power is 5 Watts.

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

Sound turns on the transmitter, which operates in the FM radio band. A neat way to catch a thief in another room or garage. The volume of sound needed to trigger the circuit is adjustable. The two stage transmitter has good range and the circuit powers do

This is a complete AM radio for the standard broadcast band, most of which is on a single IC. Other components, such as coils and variable capacitor to make a finished radio are included. The IC is the RF Amp, detector and AGC circuitry. The IC's output d

Interesting, hand-drawn schematic for a PLL FM Stereo Transmitter, with approximately 5 Watts RF output power.

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

Aircraft radio receiver circuit that receives aircraft radio signals in the 220-400 MHz band. This kit is small and simple to build, and it's a lot of fun to listen to aircrafts!

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

The TX1 from Broadcast Warehouse is an extremely high quality stereo FM transmitter that complies with FCC Standards, meaning that it can be used for commerical broadcasting. Output power is 1 Watt.

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.
