Abstract : A Common-User Radio Transmission Sounding System (CURTS) is tudied. It is demonstrated that oblique ionospheric sounders can find usable frequencies during periods of a disturbed ionosphere and that usable frequenciesuring both average and disturbed times, a communications circuit operator can use a sounder to improve performance. A systems operational concept for use of sounders is described and analyzed. It is concluded that common use of sounders is desirable and necessary for purposes of interference reduction, optimum utilization of equipment, and minimum cost. Problems thcan be predicted with high accuracy for periods of a quarter of an hour or more during times of average magnetic activity. During both average and disturbed times, a communications circuit operator can use a sounder to improve performance. A systems operational concept for use of sounders is described and analyzed. It is concluded that common use of sounders is desirable and necessary for purposes of interference reduction, optimum utilization of equipment, and minimum cost. Problems that have risen during field tests are discussed, as well as unresolved technical and operational questions. It is concluded that sounders are a promising operational tool but that certain questions must be settled by additional st dy and field tests before operational employment of sounders is undertaken.
