FM TRANSMITER 3Vdc

FM TRANSMITER 3Vdc

powerful FM Transmitter circuit we've seen that operates on such low voltage (just two AA cells). A range of 200 ft can be expected and, given a good antenna and FM receiver, over 1/4 mile can be expected. An external power supply can be used up to 9 volts. Transmits to the FM radio band, which means you can use any FM radio to receive the transmitter. Teaches basics of FM transmitters. Microphone is included.
