Edwin Howard Armstrong; he patented the system in 1933.
The HF to 7006, a notable model of high-frequency radio transceiver, was introduced in 1999. This equipment is designed for various communication applications, particularly in amateur radio. Its features and performance have made it a popular choice among radio enthusiasts since its release.
Radios are electronic devices which grab signals and turn them into sound. They are composed of electrical circuits and of the various electrical and electronic components that are needed to make those circuits which in turn make the radio itself work.
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
