(meteorobs) Stardust Radiometeor Data, January, 2000



STARDUST  RADIO-METEOR OBSERVATORY DATA  FOR JANUARY, 2000

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 ( 4420 feet) 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(500 feet) 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 forty 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 .format..
