RECEIVING RADIO WAVES– Simple experiments to show how radio waves are created.
MAKING A RADIO TRANSMITTER- This is another alternative to generating radio waves and propagating a signal.
SENDING RADIO WAVES– This video shows how to make a simple radio transmitter by using a buzzer, coil of wire and aluminum foil capacitor. This emulates the method used by the earliest radio wave transmitters.
RECEIVING RADIO WAVES- The transmitter above is replicated with a diode and crystal earphone making a simple receiver.
