Notes:
. no corrections for radiant position made to the counts
. - = no observations made
. * = Interference
. Because I am in the process of moving my antenna is now indoors and the
results may be low. I hope to get back into listening sometime in
mid-February or 1st March. I want to test the system at the new place to
find a good spot to set it up.

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.

Location: Roden, Netherlands (06 26' E, 53 08' N)
Frequency: 55.275 MHz
Transmitter: Spanish TV channel E3 (video); transmitters in La Muela (30 kW),
Gamoniteiro (50 kW) and Aitana (60 kW); all stations within
100 Hz of nominal frequency; distance ~1500 km
Antenna: 3-elements horizontal Cushcraft 50 MHz Yagi tuned to 55.3 MHz;
geographical azimuth 210 degrees (SW)
Receiver: Yupiteru MVT-9000 in USB mode; sensitivity 0.5 uV at 12 dB S/N
Observing: 800 Hz audio signal from ear-phone socket was rectified,
digitised and fed into a PC via the parallel computer port.
HP VEE was used to process the digitised signal and to store
15-minutes counts of reflections stronger than 0.22 uV
(-120 dBm). Also for all individual meteors date, time,
duration (dead time) and maximum signal are stored.

Notes:
. "E" weak E layer sporadic
. "in" artificial interference.
. The sensitivity of the new AR-5000 receiver may be superior to PCR-1000.
At first glance many tiny meteor signals could be detected (with the
same antenna and data sampling equipment)

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 rapidly 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 recent 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, non-commercial (second hand) sale of radio equipment,
available software.
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.
Those not having access to E-mail can obtain a printed copy free of charge
from J. Van Wassenhove (current or back-issues).
