Measurements on a Short Path,hop, for example) by-taking measurements on the incoming wave. As an example of the complications which occur in practice on even such a simple communications path we will consider the results of measurements taken at Auckland on transmissions from Brisbane, a distance of 2,250 kilometres.

Location of the Absorbing Parts of the Auroral Regions,oles. The position of the line of maximum aurora, when measured at a fixed location, appears to move N and S during a 24 hour period, being furthermost from the equator at midday. From these well-known observations, it seems probable that the auroral region, of some relatively stable shape, pivots a

Seasonal Variations in Direction of Arrival,0 to 2100 GMT. Nevertheless, it is possible that some limits to this variation could be indicated by an investigation of the average behaviour over a long period. Such a series of results is presented in figs. 10.1, 10.2, 10.3 and 10.4. These figures show the relative number of times in particular b

Sudden Bearing Changes,n briefly a phenomenon which appears to be quite common in those cases of near-antipodal propagation with which we are concerned here. In very many instances, it has been noticed that the received bearing changes by a large angle in a very short time. Changes of 30 in 2–3 minutes are not uncommon. S
