- Early ionograms. In manual ionosondes, observers measured the time delay of radio echoes (represented as a pip on the cathode-ray display or on photographic paper) and plotted their half-heights for given frequencies (upper image). Automatic ionosondes automated this process by directing the cathode-ray traces onto moving film (lower image).

- A map showing the locations of ionospheric stations in 1945. Since ionospheric conditions were believed to be constant along a given line of latitude, stations were arranged so that any point of interest on the globe could be connected along a parallel of latitude to the shadow of an ionospheric sounder, allowing predictions for usable radio frequencies at the original point. Three stations were in operation in Canada: one outside Ottawa, one at Churchill, and one (run by the United States) at Clyde River on Baffin Island. By 1947, Canada would take over the Clyde station and would establish two more stations on the east and west coastsTorbay and Prince Rupert, respectively.

- Radio absorption zones of the Northern Hemisphere. This map, drawn by members of OIC/6 in November 1943, illustrates the spatial extent of short-wave radio disruptions, which coincides roughly with the appearance of visual aurora. Note its disproportionate extension into Canada.

- The manual ionosonde produced an A-scan (a), which was displayed on the instruments cathode-ray tube. Technicians measured and plotted the height of the pips to produce a manual ionogram (b). The automatic ionosonde automated the process by blanking out portions of the trace to produce a B-scan (c) and projecting them onto moving film (d).

- The ionospheric field station at Prince Rupert, British Columbia. Field stations often resembled modest cabins, and were located in isolated areas (as above) to shield them from radio interference and to protect the confidentiality of their data.

- The floor plan for the Prince Rupert Ionospheric Station. Stations were generally divided into four rooms: a workshop, an operating room, a darkroom, and an office proper. The introduction of the panoramic ionogram was meant to eliminate possibly unreliable practices in the operating room. Source: Lt. Robbins, Recommended Plan for Ionospheric Station, Prince Rupert, B.C., March 3, 1945, Directorate of Signals Army, Library and Archives Canada, Record Group 24-C-1, file 91472-1, microfilm reel C-8437.
- The LG17 photographic attachment. This technical drawing shows the camera installed as part of the ionosonde equipment at Torbay, Newfoundland. The camera was actuated by a foot pedal or set to take pictures automatically at intervals from two seconds to one minute, recording the information on a continuous roll of 35-millimeter film.

- The first ionograms produced in February 1949 at Baker Lake, Northwest Territories. Produced by E. E. Stevens, these records were the result of an arduous calibration program designed to ensure their value. Source: Letter from E. E. Stevens to W. B.
