This detector system is extremely sensitive, and any loose wire connections in the circuit will add unwanted noise to the sounds produced by the measured voltage signal. The two diodes connected in parallel with the transformer’s primary winding, along with the series-connected 1 kΩ resistor, work together to “clip” the input voltage to a maximum of about 0.7 volts.

This detector is useful for detecting the presence of signals over an extremely wide frequency range (and down to zero - DC), although the detector admittedly provides much more information about the nature of the signal if its frequency lies within the audio range. To use this detector for DC signals and for signals above the audio range may require some creativity, but it most …
