It functioned as a TRF receiver with one stage of RF and one stage of audio amplification. The radio frequency (RF) signal from the antenna passes through the bandpass filter C 1, L 1, L 2, C 2 and is applied to the grid of the directly heated triode, V 1. The capacitor C 6 bypasses the RF signal around the audio transformer winding T 2 which
A tuned radio frequency receiver (or TRF receiver) is a type of radio receiver that is composed of one or more tuned radio frequency (RF) amplifier stages followed by a detector (demodulator) circuit to extract the audio signal and usually an audio frequency amplifier.
