Discussion [of "radio direction changes and variations of audibility," with author's reply]

It appears that all of the loops experimented with in the original work were of the same form as that described in the paper which gave an asymmetrical polar curve for its directional characteristic. Accordingly, commentor Israel suggests a possible source of error in the experiments, which would lead to a different explanation of the variations in wave direction from any so far advanced. In replying the original author (Kinsley) says in conclusion that the method of measurement correctly showed the variations in directions and the large variations noted were almost always of short duration and came most frequently from midnight to 4 am. It is not likely that a single observer would be ready to note them. Only by continuous measurements over long periods of time was it possible to obtain the results reported in this paper.
