Abstract:

Thirty-eight additional radio amateur reports of the long-delayed echo LDE effect are listed, bringing the grand total to 90 in this reported series. Long in this connection means an echo lasting for more than two seconds. Although detection of an LDE is apparently a rare event, they do occur and determination of the causative mechanism may prove of value in future communication techniques. A new manifestation of the effect is reported here for the first time. It is a situation in which the only communication path between a given transmitter and a certain receiver behaved as if it contained a delay of several seconds. There was no echo, as such, to attract attention. If confirmed by similar observations, this report represents an important clue as to the causative mechanism. As further evidence of the reality of the LDE effect, the article reproduces an original log entry describing a typical LDE observed in Australia in 1937. Hoaxes, and their recognition, are discussed. In the authors view, the extra-terrestrial-origin hypothesis in explanation of the very long delays is at the moment as plausible as any other.
