VARIATIONS IN 2.2 MHz IONOSPHERIC ECHO STRUCTURE CORRELATED WITH HIGH POWER 4.5 MHz TRANSMISSIONS,
Abstract
It has been shown experimentally that certain features of the ionospheric echo structure of 2.2 MHz pulses are correlated with the on-off time of a high power pulse transmitter operated at 4.5 MHz. Photographic and electronic data are presented which show examples in which the h'(f) of the main echoes changed by a few kilometers with a characteristic time in the order of 10 to 60 seconds during the high power transmissions. A number of photographic records are also presented which show the abrupt appearance of sporadic E echoes during the high power intervals. A theoretical investigation into the possible cause for these experimental results is given. (Author)
