To check the RF stage, an audio signal can be injected in the RF stage. If the output appears at the speaker, the equipment is working properly, other- wise the fault lies in the RF stage. The Signal Injector Circuit besides injecting signals at RF, IF and AF stages can also detect signals at these frequencies.

Signal Injector Circuit. GaryC. A signal injector is a very useful and quick troubleshooting tool for signal tracing in a circuit. Using it can quickly determine the faulty stage of a radio receiver, for example. The signal injector can be applied to the speaker output, and if you hear the signal you can move to the preceding stage of the circuit.

In this circuit, the signal tracer is a low noise, high gain amplifier, with a small speaker for audible monitoring while the signal injector is an audio oscillator that acts as the signal source in the absence of an input signal being acquired. To switch between the trace and inject mode, a single pole double throw (SPDT) switch is used.
