The field-test phase of the experiment consists of an examination of six propagation paths, some of which pass through the auroral zone and some of which are south of the zone. These six paths are examined with oblique-incidence ionosphere sounders which collect propagation data between 4 and 64 Mc. Two of the paths are also studied using a phase-stable CW system for the measurement of phase and amplitude of propagated signals. The primary equipment used in the experiment, consisting of Granger Associates ionosphere sounders and of a phase-stable CW system developed by SRI, is described in this report. Author
