AM Radio Transmitter AM radio transmitter circuit, published in July 1986 issue of EFY employed only a single transistor for amplification of AF signal, modulation of AF signal and generation of RF carrier wave. Here is a circuit which produces comparatively high power and uses three transistors. If a loudspeaker functions as a mic. as shown in the circuit diagram, an output transformer should be used for impe X1 : 9V AUDIO OUTPUT TRANSFORMER USE 2X1 TYPE ANT.

On switching the transmitter on, he should be able Let us look at a system that removes the carrier at the transmitter and regenerates it at the receiver. It is easy enough to modify the transmitter to eliminate the carrier. Review the circuit diagram given previously for an AM transmitter (Figure 6.2a). If we replace the bias battery by a zerovolt battery (a wire), the carrier disappears. The resulting signal is known as DoubleSideband SuppressedCarrier (DSBSC). To restore the missing carrier we might try the receiver circuit shown in Figure Build Your Own Transistor
