WebHe raised the antenna and grounded the transmitter and receiver. Marconi wanted to concentrate the signal into one spot rather than the signal beam being spread out. It made the device capable of receiving and emitting signals to up to two miles in range. Marconi’s experiments were successful, and this meant that his invention needed more funding.

WebGENERAL. First built in 1942, the CM11 was a transmitter/receiver that was capable of operation in the 375 KHz to 13.5 MHz range. There were two distinct bands of operation: 375 to 515 KHz on low frequency and 1.5 to 13.5 MHz on high frequency. In the high frequency band, the CM11 could be used with crystal or master oscillator frequency control.

WebThe receiver (figure2b) made use of Marconi's own version of the coherer - a form of shock-excited switch - connected between the antenna and earth as the detector of the electromagnetic waves. After responding to an electrical impulse, the coherer was restored to its non-conducting state by a 'tapper', which operated within a feedback circuit.
