The HF radio wave environment within the ionosphere is mainly formed by solar or terrestrial artificial and natural radio sources. An equipment adaptive to the usual ionosonde which is conducted in HF band every 15 min. routinely has been designed so as to enable the reception of interference outside the time interval to receive the observed wave. Using this equipment, successive variation in signals and interferences was measured and the HF radio wave environment there was observed. This report presents the construction of the modified ionosonde and some interpretations for the observational results.
