but it’s astoundingly simple and in the early years of the 20th century it offered a huge improvement over the much simpler tuned radio frequency (TRF) receivers that were the order of the day.
The principle of a regenerative receiver is that it takes a tuned radio frequency receiver with a wide bandwidth and poor performance, and applies feedback to the point at which the circuit is ...
Also called a "tuned radio frequency" (TRF) receiver, it is a radio receiver that detects and demodulates the carrier signal broadcast by the station without using an intermediate frequency (IF ...
In 1960, radio astronomer Frank D. Drake ... and would constitute a universal “hailing frequency.” A single 100 Hz channel receiver was slowly tuned up and down the dial to cover 400 kHz. Drake ...
