Flemings transmitter

In order to meet the requirements for a transatlantic transmission, a totally new form of transmitter would be required. One with a far greater power generation capacity was needed.The task of designing and developing this new radio transmitter fell to Ambrose Fleming. He was Professor at University College London and a consultant to Marconis company.In Flemings transmitter an alternator charges the capacitor C1 through a circuit that is resonant at the alternator frequency. Sparkgap S1 discharges to create a higher frequency signal and the step up transformer then steps up the voltage to charge C2 to a much higher voltage. Spark gap C2 which is wider then discharges C2 through a circuit that is resonant at the radiated frequency to which the aerial is also tuned.
