High frame rate of cloud to ground leaders before a main strike

Hi Everyone, 

I live is Lisbon where there are 3 active antennas, but I saw that there are no antennas in Azores... in middle of Atlantic ocean!!!

I have a friend that live in Azores(Flores Island) My question :

Just one antenna in Azores is enough to localize lightnings or the minimum is 2 or more antennas ?

Thanks in advance,
Paulo

I was looking all over the internet and could not find any graph or dataset containing for number of lightning per year for last few years/ decade.
I'm trying to figure out is there a correlation between changes of average world temperature and number of lightning.  Is it possible to get such data from you?
I assumed such data is readily available somewhere on the net but only thing I found is number of fatalities.

I was once again mesmerized by watching the lightning activity in the US, and jumped over to check on my controller status, something that I've not done in awhile which is testament to the robust nature of RED.

I noticed I have sent nearly a million packets, and while some were noise, it reminded me that the controller hasn't been rebooted in a long time.

Question:  Is there a right way to do this, that is are there advantages to rebooting regularly even if things are functioning well? 

Or does it make no difference to the controller or the software buffers etc to just let it run until my power goes out or another firmware update comes along?

Are both choices equally OK? 

I just wonder if there are tables or things internal to the function of the controller that should be reset more often.
Thanks.

Hi,

It is possible contact these station owners ?

Thanks !

I have read and reread the documentation but the antenna connections are ambiguous.  Could someone please help me with some questions regarding the upcoming system blue.

1. Is it mandatory to have both e-field and h-field antennas? If not mandatory, is it advisable to have both?

2. I note system blue PCB 16.x has 3 sets of connectors for h-field antennas. Most frame/loop antennas I can find plans for only have two loops, so I assume one loop is connected to A-1 and A-2 and the other loop to B-1 and B-2. What are C-1 and C-2 for, another loop?  

3. In the case of a simple loop antenna, what are the GND terminals on PCB 16.x for? Are they left not connected?

4. In the case of a coax cable antenna I assume the central conductors are connected to A-1 and B-1 and the shielding to GND. Is this correct?

Thanks!

Hi,

I am an amateur photographer and I am interested to take lightning photos. :-)

I am alone here at Blitzortung.com or there are more people with the same interest ?

I start to use Blitzortung.com to help me find lightning in real time.

In my country there aren't so many storms, and I read that Catatumbo River, Venezuela is the beste place in the wrould to see lightning storms.

Any ideas about this ?  Some advices ? 

Many thanks in advance !

Hi All Blitzortunger's

Can you Blitzortunger's point me in the direction of drawings / designs / plans for "non Ferrite" antennas.
Loop's or wire, I need to build up physically strong (Wind Proof) antennas for a Blue system here in Falkland Islands.
I have built up all sorts of antennas for Amateur radio use over the years so construction is not too much of a
problem. I can get hold of various sections of alloy tube, wire, insulated / non insulated in various diameters.

Regards All
