Hallo,

mich würde mal interessieren, wie genau die Blitze geortet werden können? Mich würde es sehr interessieren, wo in meiner Stadt (Heidelberg) die Blitze einschlagen, wenn ein Gewitter in vollem Gange ist. Leider kann man die Karte nicht nah genug zoomen. Sind die Archive da besser? Ich überlege mir, ob ich mich nicht an dem Projekt beteilige. Ich bin Hobbyelektroniker und suche derzeit nach einem Projekt - und Blitzortung würde mich brennend interessieren. Ich habe zwar ein 40MHz-Oszilloskop, aber keinen Sprektrumsanalysator zu Hause. Und von HF habe ich leider auch keine Ahnung. Mein Bereich ist die Digitaltechnik mit µControllern, CPLDs und FPGAs. Gibt es zu den Antennen und Verstärkern gute Anleitungen?

Viele Grüße

Wrote many letters to different addresses are found here to see prices on the site .. no one answers!
So how do I contact you??
There is little information, information is not complete ..
what, who, where?
I can buy, how much .. how much will cost delivery ..
On http://www.blitzortung.org/Webpages/inde...=de&page=3
response robot ... no return address .. or anyone write .. or anyone to ask a question ..
And on forum peace and quiet .. only dead men with braids standing ..

Ну и нахрена такое надо?)))

I've been actively experimenting with sferics receiver, and TOA lighting detectors for several years. Very interested in adding a detector at my home in Central Alabama (near Birmingham) in the Southeastern US.

Unfortunately, time has robbed me of my eyesight for close-up work, and made my hands too unsteady for SMT type soldering. I'm looking for another forum member who would be willing to assemble the kit on my behalf. Happy to have complete kit shipped directly to your location. I can also pay you for your time and labor via PayPal, or money order.

If you're interested please contact me by PM or offline. I'm grateful for any assistance.

Is there something wrong with blitzortung web site. I can't update my user data. When I hit
save it goes to the European map. It does not update my information.

Something is wrong with the Blitzortung Web Site!

Has it been compromised !?

Hallo zusammen

Ich habe ein paar grundlegende Fragen zu den Signalen, resp den Channels des Systems RED:

Ich habe den Amplifier 1 - PCB 12.3 - FW 1.6. Daran sind zwei ferride rod's angeschlossen. Welche Channels sind das nun ? Channel 1A und 1B ? Auf was bezieht sich dann Channel 1C ?

Wenn ich die Signal-Seite anschaue, dann habe ich das Bild wie unten angehängt (signal.png). Ist es normal, dass ein Channel (hier eben der grüne) so weit unten ist ? Müsste sich der nicht (wie der rote) um die 0-Linie bewegen ?

Auf der Status-Seite des Amplifiers sehe ich für den Channel B dass der Trigger deaktiviert ist (amplifiers.png). Ist das so gewollt und es gilt der Selbe Wert wie für Channel A ? Warum aber kann man dann für Channel B einen Treshold definieren, wenn der dann (siehe signal.png) nicht angezeigt wird ?

Besten Dank für eure Auskunft.

Gruss Letraz

I have been experimenting with the lightning strikes and the gain factor of antenna and preamp.

When the gain is set a little to high with consideration to the antenna being too high in receive
performance we have desensitizing effect. An auto gain feature would work well . As I discovered
the newest TOA board that has come out version 10 I saw spoke of an auto gain feature. This
I guess addresses the issue I have found.

I have designed my antenna as a 2-foot pvc loop antenna with 25 turns, 22gauge stranded
wire and gain set at preamp of 43x Gain. Channel A,B jumper set on pin 2.

The preamp board is PCB 5 version 7, Data board PCB 6 version 8.

Are there any newer preamp board versions available?? Please let me know.
I will be looking into an auto gain method. Or finding a setting that fits
both distance and local strikes which will give best effciencies at 5000km
and moderate level efficiencies.

The best we can do is use a gain that will fit most instances of nearby high activity
storms as well as distance ones. Or find a way to build an auto gain preamp.

I'm building up a station for a new member.

For those considering ordering and building a kit, here's what it looks like just out of the box!

Hi all,

Yesterday, february 7 an aircraft left from Amsterdam-Schiphol airport heading to Finland got struck by lightning. There was no damage reported, and the plane finished its trip.
I read a report of someone living near the airport, reporting lightning. Reactions on the forum (http://www.weerwoord.be) suggested it could be aircraft induced. I decided to get the Blitzortung data, and found the time to be 19:54:51 and the location was 52°20'20.9"N 4°41'05.4"E
Then i looked for flight-data available on the internet, and checked if there was an airplane at that location at that time. There was! The Blitzortung registration of the strike and the aircraft location at the time were less than 1 km apart... Impressive, right?

On two recent occasions I have checked participants and found that my system was listed as "Idle". On the first occasion I powered my system down and restarted it and it came up as "Running". When it happened second time I had a close look at Blitzortung.Org and found that my system as making detections and reporting lightning strikes but it was not passing through my server. On the second occasion I recycled my server and again the system began to function normally.

Today I checked all users and there were six "Idle" systems. I would like to get participants experiences with this issue and try to understand why it happened and find out the best approach to eliminating the problem completely.

Cheers,
