Description: Man-made radio noise was examined at 37 HF receiving sites spaced at wide intervals around the world.  The measurements were made with the goal of understanding the temporal and spectral structure of each example of man-made noise, determining the sources involved, and developing procedures to minimize the impact of man-made noise on signal reception.  All measurements were made at the input terminals of receivers at each site as contrasted to the more traditional field-strength measurement of radio noise collected by a monopole antenna.
