In Bangkok. Thailand, the fluctuation of television broadcasting signal as seen at the time of interference wave dependence was observed. The signal level varied in sine wave form, and was to repeat the rise and fall of the signal level several tens times. The number of occurrence of the quasi-periodic level fluctuation exceeding 1 dB was sometimes more than 50 times in one hour. As to the maximum amplitude of the fluctuating level, the large attenuation exceeding 30 dB was observed rarely. The quasi-periodic level fluctuation is observed every day in Bangkok. Between the occurrence number of quasi-periodic level fluctuation and appearance time, clear diurnal variation characteristic is not observed, but it tends to occur more in daytime.
