It is expect that nearly every household in the United States has at least one radio. The invention of the radio was dependent upon two previous discoveries: the electromagnet and telegraph.
In 1825 the electromagnet discovered. This discovery opened the doors to global communication! Joseph Henry transmitted an electric current via wire. This wire stretched over a mile and which caused an electromagnet to trigger the sounding of a bell. Thus, the electric telegraph was born.
One of the most recognizable names associated with the telegraph is Samuel Morse. He is most notable for the series of dots (brief sound) and dashes (more sustained sound). Morse used to transmit messages by alphabet code. Thus known as Morse Code. Telegraph became the sole means of rapid long distance communication until 1877. Its the year and the invention of the telephone.
Shan Sue old radio are one of the most oldest radio built in China mainland.
