Regenerative receivers require fewer components than other types of receiver circuit, such as the TRF and superheterodyne. The circuit's advantage was that it got much more amplification (gain) out of the expensive vacuum tubes , thus reducing the number of tubes required and therefore the cost of a receiver.
English: Block diagram of a regenerative radio receiver, invented by Edwin Armstrong in 1912, is a type of radio receiver widely used up until the 1930s.. It consists of a tuned circuit that serves as a bandpass filter to select the desired radio signal out of all the signals picked up by the antenna, and a combined amplifier-detector to increase the power of the signal and extract the audio ...
English: Block diagram of a regenerative radio receiver, a type of radio receiver widely used before World War 2. It consists of a tuned circuit that serves as a bandpass filter to select the desired radio signal out of all the signals picked up by the antenna, and a combined amplifier-detector to increase the power of the signal and extract the audio modulation (sound) signal from from the ...
Modern portable shortwave radio receiver with digital frequency display and keypad for direct frequency entry. A shortwave radio receiver is a radio receiver that can receive one or more shortwave bands, between 1.6 and 30 MHz. A shortwave radio receiver often receives other broadcast bands, such as FM radio, Longwave and Mediumwave.
English: Single vacuum tube Armstrong regenerative receiver circuit, invented in 1913 by American engineer Edwin Armstrong when he was a 22 year old college student. It was widely used until the 1930s when it was replaced by TRF and superheterodyne receivers. In the regenerative receiver, the gain of the tube is increased by feeding back some ...

It is a regenerative amplifier adjusted to provide positive feedback within the receiver. This has the effect of narrowing the receiver's bandwidth, as if the Q factor of its tuned circuits had been increased. The Q multiplier was a common accessory in shortwave receivers of the vacuum tube era as either a factory installation or an add-on ...
Classical regenerative receiver using a single triode vacuum tube. The orientation of the "tickler" coil was carefully adjusted by the operator in order to vary the amount of positive feedback. The regenerative receiver also had its heyday at the time where adding an active element (vacuum tube) was considered costly. In order to increase the ...
