This circuit allows the detection of RF signals using the lowest range of direct currents of a common multimeter. Equivalent diodes such as 1N34 can be used. The circuit is assembled in a ballpoint tube.
We found this circuit in a technical documentation from the 1980s. The circuit is from Texas...
