  Ortungswinkel - locating angle
Posted by: hans.mayer - 2015-10-02, 17:10 - Forum: Website, Maps and Applications - Replies (2)

dear all, 

what is "ortungswinkel" ( locating angle ) ? 
today i noticed a stroke at  02.10.2015 16:12:34.826867174 UTC
location of the lightning was Lat/Lon: -4.405123 / 18.224421 
my possition is: 16 17' 1" East 48 8' 57" North --> JN88dd45at

www.lightningmaps.org tells me that Ortungswinkel is: 189 degress 
accidentally i noticed i get a different value if i calculate the angle. 
on my linux box i have a command line tool called "qth" which tells me 178 degrees.
if i use google earth the result is 177.55 deg which is as rounded value the same as qth's result.
but both are quite different from the result of lightningmaps.org

on other hand i can't believe that ightningmaps.org does bad mathematics.
so my question: what is this value for called in german "ortungswinkel" ? 

kind regards 
hans

  NeB Q: Will nearby FM Radio Cell towers cause problems
Posted by: br1ght - 2015-09-18, 20:20 - Forum: Hardware, Software, Lightning Physics - Replies (2)

HI All,
I am considering purchasing a Blue (once available) and setting up at my house. My concern is that I have a cluster of several large (120-170 m tall) towers within a 0.3 km of my property. One or more at broadcasting at 93.1 MHz. another lower tower is a cell that may be using HSPA+ technology and eventually LTE... the cluster is due west of my property the direction which most of our Tstorms approach from. 

My question is, will the 'wall of towers' interfere with receiving approaching storms? I realize their broadcast bandwidths are well above the VLF of lighting but will their close proximity limit the receiver's reach to the west  Huh  TIA

  Infrasound
Posted by: Bonzo - 2015-09-15, 16:57 - Forum: Hardware, Software, Lightning Physics - Replies (10)

I am wondering whether it would be useful to add an infrasound detector to the Blitzortung System.

Obviously it could register the sound of thunder of a local thunderstorm and add some time information. At least for regions with high station density.

But moreover, there seems to be a correlation of infrasound and the appearance of sprites. [1]

So, to register pulse profiles of the EM wave in conjunction with the infrasound profiles would add a fundamental research experiment to the system.

The sensor could be realized by means of so-called microbarometers. That has to be evaluated. Also the effect of interferers like wind turbines en stuff.

This is just an idea, not a proposal.

What do you think, it this interesting? Feasable? Desirable? Are there people out there that have the skills (and interest) to add according algorithms to the existing software?

Or is that completely out of interest for this project?

BTW: I am connected with the LOFAR radiotelescope [2] where some stations are also equipped with infrasound detectors as a part of the infrasound array of the Dutch meteorology institute KNMI.

cheers

  Green System PCB 6 Ver 8.0. No Green Light
Posted by: Kalamara - 2015-09-10, 03:38 - Forum: General Discussion - Replies (12)

Just tonite I had finished installing the antenna outside. I turned off the Green system board Pcb 6 ver 8.0


Now when I go to start the tracker program its starts up and then it shuts down right after 2 or 3 seconds.

I have the yellow light blinking GPS blue light  timer to GPS flashing every sec and the red light is on.

Now I dont see the green light going on it is off.  Undecided

Is there any procedure to hard reboot this board so I hope to get the default settings working again and that
the software tracker would be able to communicate to the data board. Sounds like the software is not able to
communicate.

As an update as of 1216am DST I just was able to get the green to stay on by setting the jumpers back on
for the GPS at 9600 baud now thats ok but now the software tracker loads up then shuts down a few seconds later
darn it! Confused  Dodgy Sad

Thanks  Blush

Hallo,
unter My Blitzortung werden meine Statistiken nicht mehr aktualisiert.

http://www.wetterstation-schlangen.homepage.t-online.de/Blitzortung/?bo_page=statistics


Ich habe den Cronjob schon manuell ausgeführt, da kommt keine Fehlermeldung.
Wo könnte ich da suchen?
Kann ich im Admin Bereich was machen?

Hier sind die Statistiken vorhanden.

  Would a station in northern England be any use?
Posted by: G3WGV - 2015-09-01, 22:01 - Forum: General Discussion - Replies (12)

Hi all,

Just found this very interesting site and it looks like a fun thing to do. I see that there are lots of UK stations already but a fairly large gap in coverage between the Manchester area and Edinburgh. I'm in central Cumbria, up near the Scottish border, so more or less midway between the existing stations. I have a very quiet rural location and plenty of room to experiment with antennas, etc. Like many on here, I am a radio amateur, active on HF CW. I'm also a light aircraft owner/pilot, so I have more than a passing interest in the weather.

Would a station up here be of value, or is there already sufficient coverage in the UK?

Regards,

John

  Stationsymbol colors on the map?
Posted by: hazet - 2015-08-31, 07:58 - Forum: Website, Maps and Applications - No Replies

Hello
Just noticed "yellow" colored station symbols on the map. In the station list my station is marked as idle. Many stations in southern France are actually marked as idle . . . However If I look at my station status, it's is marked as normal? Can anyone explain this discrepancy? Additionally, I would suggest to add a legend for the different station symbol colors on the left side of the map. Red=interference, yellow=idling, green=operational, gray=offline.

Greetings from the Provence

  Detect H field from magnet?
Posted by: mvdswaluw - 2015-08-28, 06:49 - Forum: Hardware, Software, Lightning Physics - Replies (3)

Hello,

I would like to know if any of you have tried to see if variations in the H-field could be detected if you move a magnet in front of a ferrite antenna.
It would probably need to be moved/waved a bit fast because of the low pass filtering in the preamps to see anything.

The reason why I ask is because I want to see if I can make a system to detect magnets being brought into a fitting room.
Shoplifters use strong magnets to take of security labels. If you can detect their magnets, you can catch them in the act.

I already have a system that can detect a magnet at about 30cm, but I want to extend this to about 80-100cm.
The (leaked) pictures of the system blue preamp look a lot like what I had in mind to make, but in my case with low pass filtering and probably a lot of gain.

Milan.
