Improvements in the manufacture of personal transmitting emitting devices, essentially characterized in that the elements that make up a Herzian wave transmitter and receiver circuit at the same frequency, are made in such a way that a considerable number of them are in permanent operation and only a part, in a small amount, is specific to one or another function, being put in circuit, where appropriate, by means of a switch that determines the operation of the apparatus as an emitter-receiver or as a receiver of medium waves, and, in the first case, by means of a pulsating switch that determines the use of the circuits as emitters or receivers at the fixed frequency.
