Suddenly there sounded the sharp click of the tapper as it struck the coherer. |
This was in 1894, and the combination of oscillator and coherer actually formed the first real wireless set. |
We now found that the coherer would respond when the spark coil was operated several feet away. |
One wire from the coherer is connected to the aerial and the other to the ground. |
The sensitive part of the Marconi receiving apparatus is the coherer. |
The tapper then ceases to function and the coherer is ready for the next wireless signal. |
