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

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.

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

Hallo,
ich hätte ein komplettes System RED abzugeben:
PCB 10.3 / 12.3 komplett bestückt und funktionsfähig aufgebaut
inkl. 2 elektr. geschirmter Ferritantennen, GPS-Antenne und Netzteil.
Bei Interesse, bitte PN an mich.
Viele Grüße, Axel (DL8NDG)

| Stationsymbol colors on the map? |

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? |

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.
