1. A method for radio transmitting a digitized message of little depth of information in a power-saving manner by transmitters with limited power reserves in an environment of periodic radio interference sources generating periodic disturbances, wherein the method comprises the steps of:

  • transmitting the digitized message of little depth of information in each of a transmitting pulse;

    for each said transmitting pulse, transmitting the digitized message of little depth of information with a data transmission rate which is at least of such a magnitude that a length of the transmitting pulse in time is shorter than a length in time between the periodic disturbances; and

    wherein a message of a same content is transmitted at least a second time, a period of time between the transmitting pulses of the message of the same content being one of predetermined and randomly selected; and

    wherein the period of time between the transmitting pulses of the message of the same content differs from integral multiples of interference signal periods of the periodic disturbances, within a range of the signal pulses.
