In reading the material about setting up a station, it is mentioned that high voltage power lines can cause interference. I am located on the fourth floor almost level with residential power lines that are 100 feet away. I assume these lines are only a few kV, they are not the high kV lines on metal towers seen running across the countryside. Even so, would the noise be such that I should forget about setting up a station?

I notice in the information given about setting up a station, that "direct" connection to the internet is specified. I would take this to mean an Ethernet connection. Since I don't have that capability, can I get by with a USB connection to my wifi connected PC?

Here is what I have left of System GREEN - anyone interested?
At least two of the systems was function (in the box I had running until System RED)
There are many models, also some of the early.
Has been used operationally and for tests.
There is NO warranty or support.

I've ordered a kit, and I've put together the loops. After testing them, I think I'd like to use them in my shack, which means I need to find a place on the board to pull the RF out. I was thinking directly after the first gain stage, before the signal gets to the filters. Is there an accepted method of doing this? I'm hesitant to pull the signal off the board directly into a coax to the shack, and thinking I'd better use a buffer amp. It'd be nice if a tried and tested method was out there, rather than reinvent a method.

Is there a color chart somewhere that shows the time line of a strike? I see that they change color and am not seeing anything to show me how long it has been since the strike happened. Certain customers shut us down due to lightning and we have to wait 30 min from the last strike within eye sight. I found this and would like to use it more often but i need to be able to prove that we are in the clear. Any help would be appreciated.

Morning All,

I have completed building the amp and controller and they are working great, just need to build the antenna.

I have the 200mm ferrite rods supplied by Blitzortung and was looking at the various instructions and guides etc. but I'm a little bit confused and hopefully someone with so more knowledge can help this noob.

In the guides it says to try without the shielding first to save some effort, and then also recommends to use ribbon cable to shield PVC conduit if required.

Why not use copper pipe instead on pvc conduit wrapped in ribbon cable, to me that would be the ultimate shield or is it a case of that it would be too thick or is there something else I'm missing?

Alternatively I was planning on using the pvc conduit wrapped in adhesive aluminum foil .

Please can you point me in the right direction before I head off to the local DIY store to pickup the bits I don't have. (I'm fortunate to have outdoor shielded cat5 and shielded rj45 connectors left over from my CCTV install).

Thanks,
Dave

Hello Forum,

we have Problems to get our Controller running.
After Power On the Buzzer beep´s a while.

Here are several Log after Power On.

Can somebody help us?

Hi

I've been following Blitzortung for a while now and have noticed that coverage in northern Norway is quite poor.

We've had several thunderstorms up here the last few weeks and as soon as they go north of Helgeland most of them go unnoticed by Blitzortung.

I live in a rural area where interference should be pretty low, and I'm interested in setting up a station here whenever there are PCB's available again.
My coordinates are roughly 67 16'23.62"N 15 7'0.65"E

I have both the skills and all the required equipment for assembling the detection hardware.

Thank you

Hallo Forum,

ich vermisste hier auf Blitzortung.org die Dokumentation des Systems und der Platinen und deren Stücklisten für die Materialbestellung. (Und wenn sie doch da sind, finde ich sie nicht.)

Ich habe nämlich die Platinen von Egon bekommen und suche gerade die Stücklisten. Dadurch das ich sie hier nicht gefunden habe, habe ich mal G.... benutzt und da auch was gefunden, aber es würde schon besser hier auf Blitzortung passen und nicht im Internet verteilt sein.

Wäre super entweder einen Bereich direkt auf Blitzortung.org machen oder hier im Forum.

Danke und Grüße,
Oliver

New here - Hope this is the correct place to post this idea.

I am impressed with the lightning detection network that your group has developed. From what I briefly read and understand, the lightning is triangulated by using a time on arrival to sensors at known locations. Taking this application a bit further, could a similar type of system/network be utilized as a earthquake detection/alert system?

I saw this story on NPR about earthquake detection /early warning systems (1) and now California is going to start spending some money to have these installed (2). This got me to thinking about this lightning detection network that you have collectively set up. Would it be possible to set up something similar like this (3) or (4) using your backbone of lightning detection (but forked independently) as the basis for a early warning system? Maybe this could be open-sourced and or crowd-sourced and receive some of the funding from (2). Homemade earthquake detectors appear to be reasonable in price and affordable to build (5) or (6). These could then work together in a similar manner as for lightning detection sending out text message alerts/warnings (7) when a certain number of stations detect seismic P-waves.

From what I understand, a couple of seconds of advanced warning before an earthquake hits will save a lot of lives.
