摘要

Improvements in the tuning indicators applicable to radio reception devices, characterized by the arrangement of a circuit induced by the antenna circuit, equipped with an intermediate rectifier that facilitates a continuous corriene component proportional to the antenna signal, passing to an amplifying transistor and a second transistor, which has two luminous pilots interposed one of which is visible from the outside and the other, of reinforcement, is not visible, so that the decrease in the brightness of the first to reach the minimum indicates the maximum precision of the tuning performed on the device.
