Abstract: This report presents the results of two weeks of bi–directional high frequency radio path soundings in a trans–auroral environment between Christchurch, New Zealand, and the U.S. station, McMurdo (Black Island), Antarctica, during mid–January, 1992. The work was commissioned by the Naval Undersea Warfare Center, New London, CT, for the National Science Foundation. This investigation demonstrated the value of ALE adaptive radio systems as a real–time frequency management tool. Based on the results observed, the authors recommended that NSF consider the acquisition of a 1–kW ALE radio system to be used, primarily as an oblique ionospheric channel sounder, with their existing communications system. This addition would provide significant improvement to the NSF frequency management capability.
