  • 3-Valve Battery Powered TRF Receiver Circa Mid 1920s

    TRF receivers were the most common type of radio receiver in the early days of radio broadcasting. They are relatively simple in design, using a tuned radio frequency stage, a detector stage, and an audio amplifier stage.

    The reaction in this receiver is possibly controlled by the twin honeycomb coil coupler. The coil coupler is used to tune the receiver to the desired radio frequency. The reaction is a type of regeneration that can be used to increase the gain of the receiver. However, it can also make the receiver more difficult to tune.

    The receiver has both loudspeaker and headphone connections. This means that it can be used for either loudspeaker reception of local stations or headphone reception of distant stations.

    The frequency band of operation and manufacturer of this receiver are unknown.
