FM Transmitter 2 Transistors
The circuit of FM transmitter 2 transistors in the picture below was made using two transistors BC458. The circuit of FM transmitter 2 transistors work on the FM frequency range 88MHz – 108 MHz. The circuit of ‘FM transmitter transistor 2’ has a projection distance of up to a distance of 20-30 meters. To operate ‘FM transmitter transistor 2’ is necessary +9 volt DC voltage source which can be supplied through a power supply or battery. The circuit of FM transmitter 2 transistors is quite simple and can be easily assembled. To assemble FM transmitter 2 transistors can be seen following circuit scheme.
The Circuit Of FM Transmitter 2 Transistors
At The circuit of FM transmitter 2 transistors above using a coil that must be made using containers with ferrite core 5 mm and 0.5 mm wire-ridden email as much as 7 coils on the containers. Function coil L1 on the FM transmitter 2 transistor circuit is to determine the operating frequency range of the transmitter, to select the operating frequency can be done by turning the ferrite on the L1 coil at the desired frequency range. FM transmitter 2 transistor circuit in the image above using the microphone input of elektret. Application of FM transmitter 2 transistor circuit can be used as a wireless microphone as the sender or the FM signal into an FM radio receiver.
Usage The Circuit Of FM Transmitter 2 Transistors
Although the circuit of FM transmitter 2 transistors is only able to emit a maximum of 30 meters, but to activate a circuit of FM transmitter 2 transistor is to note the working frequency is used so as not to interfere with the reception FM transmitter broadcast to another, so it needs to be determined first empty frequency, then setting the working frequency of the circuit of FM transmitter 2 transistors.
