Radio frequency transmitter and reciever

Ok I own do the fm transmitter with variable frequence ranges from 88 to 108 it is simply todo and working is also nice
In this main components are l and c mean capacitor. And inductor form a tank ckt
F=1/2piRC
Here first transistor use like modulation product of input signal and dc current gives to the supply voltage
tensing transistor boostup the modulated signal
And also inductor is not variable hence use only variable capacitor in range from 2-22pf called as trimmer capacitor,here of called as picofarad
every circuit which available in internet just type in search like own making fm transmitter circuit
Any doubts contact me via email #-Link-Snipped-#
