Coherer radio detector history electronics notes

The coherer was a very early radio wave detector. it was used for detecting the signals for many early wire-less transmissions. the coherer was used with the spark transmitters of the day these transmitters used a high voltage, often created by an induction coil arrangement, and this was then used to create a spark, and the resultant signal was radiated by an antenna connected to the.
