Wireless microphone - Basic electronics circuits

This simple FM wireless microphone transmitter can transmit speech over a short range. It can be used as a simple cordless microphone. The circuit uses two integrated circuits from Maxim.
Using a wire antenna of about 75 cm the transmitter should have a range of about 35 m. Try to keep all leads as short as possible to prevent stray capacitance. The FM wireless microphone transmitter operates on a single supply voltage in the range 4.5 V to 5.5 V from any standard battery source.
