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
available for further analysis. Reduction software for DOS and
Windows available].

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 (06º26'E, 53º08'N)
Frequency: 60.500 MHz
Transmitter: French TV channel L3 (video); transmitter in Carcassonne (100
kW),
distance approx 1150 km
Antenna: 3-elements horizontal Cushcraft 50 MHz Yagi tuned to 55 MHz;
geographical azimuth 195 degrees (SSW)
Receiver: Yupiteru MVT-9000 in USB mode; sensitivity 0.5 uV at 12 dB S/N
Observing: 800 Hz audio signal from earphone 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 10-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.
Dead time corrected hourly counts for signals stronger than 0.22 uV

Notes:
* affected by direct reception due to tropospheric or ionospheric propagation
# local interference
- no observations
. Due to the uncertain situation of the Spanish TV transmitters on channel E3,
I switched to a French transmitter on 60.5 MHz. Unfortunately, this results
in half as much reflection. There are still two Spanish transmitters on
55.75 MHz, so I could have waited a little.
. A lot of continuous or almost continuous reception during the Perseid.
I had to throw away quite some counts.

Notes:
? probably affected by Es.
When no figure is shown, the equipment was out of service.
. The Perseid meteors appear to have been with us from late July until the
end of August with no spectacular peak.
Elevated counts this month appear to have come from the Perseids,
delta Aquarids, delta Arietids and other minor showers.

. the tail end of the delta Aquarids activity, a zone of Perseid activity
and possibly some daylight gamma Leonids activity are visible.
The Perseids were not very strong here, being so far south and my
antenna is pointing SW also.

. some Tropos during the nights in late July.

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).
