The Use of Radio Field Intensities as a Means of Rating the Outputs of Radio Transmitters

A method is described by means of which the outputs of radio transmitters could be regulated by Federal authority as required by law in terms of measured radio field intensities instead of watts power in the transmitter or antenna circuits. The method was developed from surveys made on five different radio broadcast stations. For purposes of example, figures are given only for radio broadcast stations. The figures given may not be those which might be ultimately desirable for regulation purposes; however, they are usable as a means of explanation and demonstration and, therefore, serve the purpose for which this paper is intended. The method is developed on averages taken from actual measurements and is applicable to all conditions found in the broadcast band at the present time.
