If after doing this, you can not tune the transmitter, you can adjust the coil that makes up the oscillator circuit by joining its turns to raise the frequency, or separating them if you want to reduce it a bit. Choose a radio frequency that is not being used or one that is way below or above local radio station frequencies. Then slowly vary in that area, when transmitter and receiver frequency matches you can get the clear output from radio. For example if you want to receive a FM radio station on 103 MHz so you have to make the antenna for 103 MHz with the help of calculation. The signal emitted by it can be tuned from its FM radio because its transmission frequency can be easily located between 88 and 108Mhz. Connect the kit to the power supply board, align towards the radio and use a screwdriver to adjust the oscillation coil L until the radio catches the signal.
