Location:  Deurle, Belgium  (3 37' E, 51 00' N)
Frequency: 66.29 MHz since July 2001
Antenna:   crossed Yagi (x form), 4 elements, astronomical azimuth 270 deg
           (= E), elevation 27 deg.
           Antenna amplifier: 25 dB  max level  90 dBmuV
Receiver:  commercial, Progresson 447A, TESLA (Bratislava)
           The receiver was calibrated with a Marconi TF2008 signal
           generator. Sensitivity: 5 muV (modulation frequency
           1000 Hz, frequency sweep 38 kHz) at (S+N)/N = 20 dB.
           SWR of antenna alone at 66.5 MHz: 1.4/1 (good to very good),
           measured with MFJ/259P SWR analyzer (HF-VHF 1.8 MHz to 170 MHz)
           on Sep 28, 1998.
Observing method: automated setup, 150 samples/second, 8 bit resolution.
           [Time and details of all individual meteor reflections are stored
           on file in the Ghent University format (Prometeos), and are

Notes:
 --: lost counts because of high noise level or machine failure.
  @: Hourly rate estimated by effective observation time less than 60 min.
 NS: unknown type of noise
 IF: Contamination due to radio noise or interference
 ES: Contamination due to sporadic E opening

Location: Astronomical Observatory, Ghent University, Belgium
          (ED50 coordinates: 3 42' 32" E, 51 01' 25" N)
Antenna (2x): 4 elements horizontal Yagi, pointed East, elevation 20 deg
Antenna amplifier: 10 dB gain
        narrow band resonance lambda/4 antenna filter
Frequency: (1)=66.29 MHz (signal) and (2)=65.3 MHz (interference control)
Receiver (2x): modified commercial FM receiver
Data acquisition: 12 bits PC-based A/D convertor, 250 Hz sampling rate
Interference rejection:
   dual setup: receiver (1) tuned at distant transmitter, receiver (2)
   tuned at empty frequency. Anti-coincidence measurement rejects
   registration of broadbanded spurious signals (lightning, computers,
   ignition motors, etc).
Further information:
   see WWW page (additional info + observational data)
   http://allserv.rug.acdot be/~hdejongh/astro/meteor/meteor.html
Data format:
   results are shown as total reflection time, expressed as
   a percentage. The actual number shows 10 times this value.
   When no figure is shown, the equipment was either out of service,
   or results could have been affected by interference, sporadic-E.

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).
