Unknown strong tone appeared March 7, 2017, trying to find solution as rates dropped. I have no idea what the problem is, if it is that tone destroying my reception or a problem with the notch filter. . did not get one reflection at all from the Arietids or Zeta Perseids!! . no corrections for radiant position made to the counts. . ( - ) means no observations made. . Zero (0) is actual number meteors not heard/seen per hour! . Broke notch filter repaired and now seems I may be getting better reflections. . as of May 30,2021 that strong tone has reappeared and wiped out 77.251 MHz!

Felix Verbelen 2. ABOUT THE RMOB The RMOB is an independent initiative of some workers in the field of radio meteor scatter observations and data reduction. It started in August 1993 in order to spread the Perseid results via E-mail. Since then, it has appeared monthly, and it has gradually been expanded. In regularly publishing summaries of observations, potential radio observers are kept up to date of existing installations, possibilities and limitations of radio meteor observations. In the long run, there should be sufficient observing stations to cover the whole globe, allowing to detect stream outbursts which may remain unnoticed visually. RMOB contains typically: summaries of previous month's observations, equipment data, first results of stream activity by radio methods, relations between radio and optical meteors, references to other publications in the field of meteor astronomy and radio scatter techniques, announcements of meetings, short questions and answers, links to interesting web sites. Contributors are mentioned, and interested persons are asked to contact them directly. RMOB can be copied freely in unabridged and unmodified form. Extracts should indicate the source (Radio Meteor Obs Bulletin, month and year). If you want to subscribe (or un-subscribe) to the E-mail distribution list, please send a message to C. Steyaert. 3.
