Colorgramme WMeteor v 1.0

Preamble

The WMeteor software functions correctly only if your radio installation is stable and can detect meteor echoes effectively. Concerning the materials necessary see the technical pages of Meteor web site.

Dave Swan (U.K) created a protocol to the test the stability of your radio installation. I strongly recommend you read it to assure that only a received signal from an echo is counted.


Meteor System Set-up by Dave Swan (UK)

How to build?

Take a 50/75 ohm plug and solder one end of a 50/75 ohm resistor to the centre pin and the other end to the outer case.

1. Connect up the system and set the receiver to the frequency in use.

Terminate the receiver antenna input in its Characteristic Impedance, this is usually 50 ohms for professional or scanning receivers and 75 ohms for Band 2 FM stereo receivers. Use only carbon resistors not wire wound.

Reset the system and adjust the Threshold controls above and below the displayed Noise level so that the system is not triggered into producing a count. If the system is triggered adjust the necessary threshold to prevent this. When the system is running with no triggering observe for at least 30 minutes to confirm no random triggering of the system.

If random triggering persists the probable cause is man-made noise getting through the power lines or computer hash usually the monitor, fit an appropriate filter.

If an RF Signal Generator is available, see Annex A.

Continuing from 3. Observe the displayed noise level and remove the terminating resistor and refit the antenna, if the antenna is a good match and there is no man-made noise present, you should see no major increase in noise.

Reset the system, and you are ready to start observing.

Changing any of the system components will require system Reset.

This set-up is to ensure that the system itself is not generating false counts!

Annex A: At this point the system sensitivity can be measured.

  • Before running ColorWMeteor !

WMeteor is foreseen to work SOLELY in Universal Time!
WMeteor uses the hour of your computer that is why it is INDISPENSABLE to configure the clock in your Windows parameters correctly.
1°) in the start menu of Windows select " Parameters " then " Configuration Panel".
2°) open clock setup.

3°) select the tab " time zone " in the list of places select " GMT hour of Greenwich, Dublin ... ", uncheck the box" to Adjust the clock for the automatic observation of the hour of summer" (only in France ???) Validate, close then run WMeteor.

  • Select English language 

By default Colorgramme WMeteor running in English language, but it is available to change the language by click on the country Flag on top of the Observer page.

  • Observer a essential sheet for a good work of the soft.

Many Part of the software use a informations filled in this page.

Your Name is used for create the name of file of WMeteor and your location infos is used in the Sky Map Part.
For a good running please fill in first your Name and the others infos then press Save button !
Here, my Datas in the Observer Form.

Observer Filled Area

  • WMeteor

WMeteor TabSheet display all control parameters to drive your Meteor electronic Interfacing.
If you don't see what is it, see http://radio.meteor.free.fr

Choose the PC?s Com Port (ex. COM1) where your Meteor Electronic Interface Box (MEIB) is connected.

Now, Meteor will adjust the sampling. The time it will take depends on the computer speed and the strength of the low-frequency signal from the output of your receiver. At the end, the colour of the trace changes from red to green and Meteor evaluate the Window?s time scan.

Wmeteor Page

At the end of sampling, you adjust the Threshold and delay time by respective scroll bars.

In this example one echoe come while I adjust the threshold !

  • Files created by Cologramme WMeteor

Colorgramme WMeteor create automatically many file necessary for work properly

STA ( Statistic ) files is a simple text file created daily for store the number of echoes counted hourly.
LEN ( Length ) files is a simple text file created daily for store the length of echoes counted hourly.
RMOB files is a simple text file created monthly for store the STA or LEN datas. This files is currenlty used by
www.rmob.org and by Colorgramme to display under graph your datas.
Colorgramme WMeteor create 1 RMOB file for your STA datas and 1 RMOB file for your LEN datas.
All files are stored in Subdirectory. It is most easy to find the searched files.

  • Histogram Functions

One simple click on check box display the datas values or not. And if you click on LEN, you see your LEN datas.

And if you click on the histogram, you have a possibility to change the color of the datas display.

  • Colorgramme

Colorgramme TabSheet display by default the current datas observed by WMeteor. This is the STA datas converted in Monthly RMOB file, displayed in small rectangles ( one per hour ) with a color representing the level measured. Red is highest and Blue is lowest. Black is no datas.

At left you see the "Live On" indicator.  This indicator visualize the time left from last refresh of Colorgramme display ( hourly ).

From Directory is available to use if your datas files is not in .../datas/sta/  ( default ) directory, but in other dirve or if your computer is in network.

Colorgramme

All buttons is for open a different files type and display on Colorgramme graph. Muli select file with <Open STA> it is available to load 1,2,3,all files. <Save image> save in BMP image format the Colorgramme graph. Curve or Histogram select the type of display of daily Stats of the month. One simple click on the Daily Stats graph permit to change the color of the graph as in WMeteor.

Max Auto check box permit a change level of visualization in Colorgramme Image.

  • RMOB Report

RMOB Report TabSheet is for send automatically by E-mail your RMOB file to the RMOB coordinator Christian. Steyaert.
To see more infos on RMOB http://www.rmob.org

Fill your Provider SMTP Host in  <SMTP Host> area.
Fill your E-mail in <From> area. Your E-mail is automatically copied in <To :> area because if you clik on <Test Send> button ( recommended), one E-mail is send to you for test.

If this test work properly, then check "Sens automatically..." case. Now all area is in yellow and you see in <To :> the E-mail of C. Steyaert and at the 1 first day at 1h of the next month your RMOB file of the currently month is send to Chris.

RMOB Report

ATTENTION : If your Internet connection don't work properly, the next E-mail is not send !  Quit the software and re-run.

  • RMOB Stats

RMOB Stats TabSheet permit to visualize and analysis the monthly datas  from the observers of the Radio Meteor Observing Bulletin  ( www.rmob.org )

Here the animated image display the main operations.

Open files with <Open Obs.> button. Multi select is available as our example. Next the files is automatically added and displayed under the graph. It is available to see the date of the maximum activity of the meteor shower. Some observers influence strongly the curve by their high count level. But if you want to optimize the curve, use Observers select combo box à right. Select an observer and then press <Remove Obs.> button. The curve on the graph is re-calculated without this observer. If you see the ideal curve then you save your datas with <Save Stats> button, and reload with <Import Stats> button.

RMOB Stats

Up right selector is for choice the month and year RMOB observers datas. In our example we chose january 2001 all datas observers. You see Mr Ylka Yrjola and Ton Schoenmaker increase strongly the curve ( high count ). Next we remove this 2 observers, but you see this is not really significant, because their high count hide only a small fluctuations while this month. Only the big peak at the begin of the month is significant. It is the Quadrantids meteor shower. The last image of this animation display only one observer ( Ghent observatory ). This part of Colorgramme WMeteor is currently in development and the new calculation functions is integrated in next versions.

  • Sky Map

Colorgramme WMeteor Sky Map is going to permit you know the sky over your antenna if  you have filled correctly the parameters in "Observer" panel in particular your Longitude and Latitude. The map presents the visible sky with the main stars and constellations. You will find the sun, moon and planets.


The mains meteor shower listed by International Meteor Organisation ( http://www.imo.net ), are represented as "stars with green sticks" and the dimension is proportional to the ZHR value. For ZHR explanation see IMO web site.
At the maximum date of the meteor shower this one is drawn in red. RADIO meteor shower is drawn in fuschia.
The axis of your antenna is drawn in yellow circle with cross.
"Hour Step" permit an adjust from UT for see the sky before or after PC time.
Carte du ciel

All the map is active, a simple clik on an object permits to have access on the informations  it concerning.
The map is refresh regularly all 3 minutes.
