To increase the range, the output must be
increased. This can be done by using
an RF transistor and adding an inductor. This
effectively converts more of the
current taken by the circuit (from the
battery) into RF output. The output is
classified as an untuned circuit. A BC547
transistor is not suitable in this location
as it does not amplify successfully at
100MHz. It is best to use an RF transistor
such as 2N3563.
