A special experiment was carried out using a high-powered transmitter and a high-gain rhombic antenna to heat the ionosphere at a distance of 1300 km from the transmitter. A Digisonde ionospheric sounder was located at the midpoint to sense any changes that might occur in the ionosphere at the heating cycle period of ten minutes. The measured phase data were processed using spectrum analysis in an attempt to detect this ten-minute period. The results are not conclusive, but there is some indication that the heating period was detected only during the nighttime in agreement with theoretical prediction.
