Note:
. Finally I have a good meteor detection software, called MSD, using a sound
card! Electric noise pulses, computers, household electrical appliances and
especially the Radio Intermodulation of TV C4 of Barcelona, make cities bad
places to use software like MCT5X or my old DATA CAPTURE software using a
14 bit AD/DA Card. In the near future I will put the software on my web site.
I am positive that the observations are meteors. The software also makes
".wav" files for further analysis.

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.

Observers: Del Dobberpuhl, John Meyer, Jack Meyer
Location: Van Andel Creation Research Center, Chino Valley, AZ. USA.
34 50' 50" N, 112 29' 50" W. Elevation 1347 meters above sea
level. Frequencies: 88.5, 88.9, and 89.7 MHz for signal FM
receivers; 87.9 MHz (currently an unused frequency) for noise FM
receiver.
Transmitter Locations: Many possibilities including: El Paso, TX;
Mesquite, TX; Commerce, TX; Abilene, TX; Farmington, NM; Colorado
Springs, CO.
Antenna: dipole housed in corner reflector built from wire screen. Open
end of reflector tilted at about 65 degrees above horizon and
facing due east.
Antenna Pre-amplifier: 27 dB gain.
Coax Cable: 152 meters of RG-8
Receiver inputs: Four-way splitter with outputs to each receiver
Receivers: Four OPTIMUS STA-80 FM receivers modified to 10KHz band width
using IF amplifiers with 80 dB dynamic range signal strength output
voltages.
Data Acquisition: DATAQ type DI-190, 2-channel module connected to computer
serial input port. Acquisition rate is 40 samples per second for
each channel. Channel one is the combined peak signal amplitudes
from the three signal receivers. Channel 2 is the signal amplitude
from the noise receiver. Data are reported only when signal
strength at the antenna exceeds -124 dBm. Storage continues for
one second after signal drops below -124 dBm.
Interference Rejection: Data storage is inhibited if interference at the
noise receiver's frequency exceeds -122 dBm at the antenna.
Inhibiting continues for one second after noise level drops back
below -122 dBm.
Data Reduction: Mostly automated computerized reduction.
Data Format: Results are shown as total seconds of reflection time per hour.
When no figure is shown, the equipment was either out of service or
results could have been contaminated by sporadic-E or interference.
Data are in comma delimited ASCII.

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
