Observer: Maurice De Meyere
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
available for further analysis. Reduction software for DOS and
Windows available].
Raw counts of reflections with a duration of at least 0.027 s
during one hour interval starting at UT:

. local time = UT + 2 hours
. the new frequency works out well, except that there are again several
zero counts at the end of the month.

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.

. we observed an outburst of meteor activity on July 6, 5h00-5h30 UT.
Mr. Brian Fuller (Australia) indicated strong activity from
radiant Position R.A. = 92 deg, Decl = +25 deg.
This could be late beta-Taurids activity.

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).
2. ANNOUNCEMENTS
2.1. Stan Nelson's projects / NASA
I am testing a new frequency using a US Channel 2 - 55.250 TV video signal
with
a TV beam pointed straight up. Using a Kenwood TS570 in USB mode tuned to
55.25119 MHz. I have been receiving pings with Gram 6 Spectragram software
at rates of about 200-240 per hour.
I will be speaking a Rob Scruggs at NASA about their setup at Marshall SFC
soon.
He uses 62.25 MHz and appears to get similar numbers with a Quickbasic
software
and A/D converter. Dr. Tony Phillips, editor of www.spaceweather.com,
sent me Rob's link that shows their current rates.
ftp://ftp.spacescience.com/pub/robsuggs/metradar.gif
ftp://ftp.spacescience.com/pub/robsuggs/bigradar.gif
Will keep you posted on further developments.
In the meantime, I am uploading 217 MHz USB audio received here in Roswell,
NM from NAVSPASUR radar continuously to NASA's server.
It can be monitored at http://qt.msfc.nasadot gov:8000/navspasur

2.2. Meeting the Argentine radio meteor team
I got a delightful encounter with Juan Martín Semegone and his team at the
"Amigos de la Astronomia" observatory in Buenos Aires.
The Argentine Institute of Radioastronomy has a very active meteor team, also
doing visual meteor observations. They have a meteor workshop every Saturday
at the observatory. Their interest goes beyond meteor counts: developing a
standard receiver and meteor physics is high on their agenda. They are even
building their own transmitter (in the 53 MHz range) for forward scatter
observations.
In particular they find inspiration in RMOB, studying the station data of the
other contributors. [See also RMOB9903].
Continued success!
