Abstract

Abstract 1. Method for the automatic search of a transmitter to locate a transmitter which transmits at any frequency whithin a predetermined search frequency range by stepwise shifting of a receiving frequency interval and investigation of the respectively received frequency band as to occupancy by a transmitter and automatic switching to another receiving frequency in the case of unoccupancy, characterized in that the search frequency range is searched in large frequency steps (R1) corresponding to first frequency intervals with a first bandwidth (BB1), in that an interval in which occupancy by a transmitter is detected is searched in smaller frequency steps (R2) corresponding to second frequency intervals with a second bandwidth (BB2), and in that the method with stepwise decreasing frequency intervals with correspondingly stepwise decreasing bandwidth is continued until a smallest available bandwidth (BBn ) corresponding to the frequency resolution capacity of the receiver is reached.
