Fm transmitter circuit 741 op-amp integrated based on a simple, stable FM transmitter circuit 9-volt battery is working with the adapter, can be used but 9v battery to a cleaner source .. author 30cm tall telescopic antenna used instead of electronics store located in the radio antenna used L1 coil of a pen on the 1 mm wire windings to be wound round 2 of 4 .3 mm range will be all ranges must be the same ….

Our project is the construction of an FM transmitter circuit for the range of commercial radio frequencies between 88 MHz and 108 MHz The transmitter is easy to build, has reduced dimensions and all components that are easily can be found in stores of venda of electrical components in storage or in your school. This provides a high power transmitter mainly in open areas and with its huge sensitivity is able to capture the minimum sound, and could even be used to carry out espionage.
