In 1900s the first transatlantic radio broadcast occurred.
During the early 1900s, several improved radio receivers were developed, including regenerative and superheterodyne receivers. These receivers had greater sensitivity and selectivity than earlier designs, which improved the ability to receive weak signals.
In a regenerative receiver, a vacuum tube oscillator is adjusted to the frequency of the received signal, so that it converts to audio and amplifies the changes to the signal that occur when the signal is modulated or keyed on and off. The superheterodyne differs by mixing the outputs of two or more oscillators that add or subtract to arrive at the frequency of the received signal, then amplifying the modulated changes in the signal.
