You can make your own radio using a few simple components: two lengths of wire (one 3 m long, and the other 6 m long),a metal rod, earphones and a detector. This is how to do it.First, the rod is hammered into the ground. Then the insulation is stripped off the end of the 3-metre wire. The wire is twisted around the rod ten times to make a good connection. ‘This is the earth wire.«Next, the detector is earth wire attached to the other end of the earth wire. ¢The 6-metre wire is now taken and one end is connected to the other end of the detector.»(l" his wire is your antenna.) The antenna is hung rod - from a tree (making sure that the bare end does not touch the earth), The two wires from the earphones are connected to each end of the detector. Finally, the earphones are put on. Now you can hear the radio station (if you are very close to the transmitter!).
