RMOJ reports the results of radio meteor observation in Japan, sent to myself. Every month, this bulletin is sent to Mr.Christian Steyaert, who publishes RMOB, which is a world-wide bulletin. In Japan, radio meteor observation has become the major meteor observation by means of development of low-price receiver and useful automatic data-taking software (HROFFT by Mr.K.Ohkawa). There are 70 observational sites in Japan, most of which utilize the radio source of 53.750MHz (50W) transmitted at Fukui-NCT(by Mr.K.Maegawa). FM-radio Observation has become difficult in Japan because of the recent increase of small-FM staions. I hope RMOJ will be helpful to radio observers, as well as all meteor observers.
