  Ferrite rod N/S orientation and connection
Posted by: dgoadby - 2018-10-27, 22:36 - Forum: General Discussion - Replies (3)

I have just got my system Blue working. I have made an enclosure for the two ferrite rods. From other posts I will connect the knotted wires to the A-1 and B-1 terminals and the others to the A-2 and B-2.

The rods are 90 degrees to each other but which rod (A or B) has to point north/south? And by "point" I mean the long axis lies on the N/S line. Obviously the other will lie on E/W.

Nowhere can I find anything other than an annotated photo show the rods with E-W and N-S but it does not say which one goes to which terminal.

As we are are generating a vector of the strike direction which will be the sum of both of the rods' signals then I assume that it does matter.

  New station issues
Posted by: dgoadby - 2018-10-27, 15:52 - Forum: General Discussion - Replies (1)

I have a new system blue up and running. It is online with all green lights, an IP address and a flashing blue - hooray! I even have a station ID. But, when I use my login I an told I have a guest account so cannot change anything.

I tried to create a new user and I am told that I already exist.

Is there a problem adding my station details at the moment (27/10/2018 @ 15:47 UTC) or am I missing something. I know there is a database problem but it is not clear what is affects other than data.

The advice given when I tried to create another login was to use the "services" section but I cannot find that anywhere.

Exclamation Global lightning dataset in txt/CSV format
Posted by: Sara - 2018-10-26, 11:50 - Forum: General Discussion - Replies (6)

Hi all!

Is there a possibility of getting access to lightning datasets in other format (for several years) (rather than just getting 1 image per 1 day).
Many thanks in advance!

Hello Folks,

I am in Auburn California, been inactive for some time but registered about 3 years back.
I am trying to reach another active monitor station that is near me.
He/she is Station 695;  Eldorado Hills a city very close by.
How can I reach Station 695 ? 
Best,  Pat Barthelow   Auburn CA   apolloeme@gmail.com

  Help info o shop KIT, new site Sardinia (Italy)
Posted by: andrillo1969 - 2018-10-03, 08:36 - Forum: General Discussion - Replies (1)

Thanks to all of you for any help; I'm new to the forum I just joined. I am a passionate dimetherology resident in Italy, more specifically in Sardinia, Capoterra (CA), an area hit in recent years by high temporal phenomena and frequent lightning. I would have the pleasure of collaborating with YOU and buying the KIT to allow the community to have further and more precise data from a region that does not own these stations, despite being at the center of the Mediterranean Sea. how can I do to buy the kit, you could cortesememte indicate the link, thanks andrea carassale, andrea.carassale @ tiscali, it

  New station in progress
Posted by: BerkshireCC - 2018-09-17, 17:44 - Forum: General Discussion - Replies (2)

I recently took receipt of the system blue.  We hope to have it up and running before the snow flys.  I do have a question or two.  I registered for the forum.  Do I need to register anywhere else as a user once the system blue gets operational? If so, where do I do that?

Thanks in advance

  Getting Participant status. Not sure what I'm doing wrong.
Posted by: michidragon - 2018-09-15, 18:19 - Forum: General Discussion - Replies (15)

So from what I can tell, to get my forum account to 'Participant' status (which I am; station 2284) - I'm supposed to log in to the blitzortung.org site, then once I can see the 'User Area' (where I define my antennas, station details, etc) - I navigate to Further Info -> Forum. 

I've done this … many times, but still my account is a "General User" and I can't get into the station areas...

I've tried the navigation from 3 different machines so it's not a matter of clearing browser cache.

Am I doing something wrong here? Missing a step?

Thanks,
Michi

  New member, having some problems with H-field big interference bursts..
Posted by: michidragon - 2018-09-14, 04:10 - Forum: Hardware, Software, Lightning Physics - Replies (35)

So I noticed some threads about interference on Blue were moved to forums I can't access, so I hope i'm not doing this wrong. (I tried to navigate from the Member area to the forum to link my account as a Participant but it doesn't seem to have worked... Tried a few times..)

I got my Blue board finished yesterday (with the LTC filter chips on each channel, and so far two ferrite rods at 90 degrees horizontal; and the amplifier attached tot he H-field port via about 1m of Cat5e cable.)

Results have not been so good.  The unit has been going into Interference Mode (Burst) quite quite often and the stroke level compared to the station mean is very low. (My station is 2284, by the way.)

I did un-knot the knots on the ferrite rod leads, because I was worried this may somehow mess with the signal (I know now that that's unlikely to be the case and was probably a bad idea as it weakened the wire; at least the ferrite rods are not too rare right now) - but I did connect the knotted leads to + on channels A and B.  

I did NOT solder the jumper pads on channels A and B on the back of the H-field amp as I interpreted this as needing to be done for loop antennas only.  I don't know if I read this wrong.

Anyhow, performance has not been good. In automatic mode the system would just go into burst interference mode quite a bit.  In Manual, with default settings, less so, but I presume this isn't ideal in terms of gain being adjusted.

I've tried to figure out what's causing the interference. At first I was worried that I soldered on one of the filter chips wrong (The orientation is correct, i'm sure of, but maybe there was a bridge or I heated one of the chips too much - ) but for sure the interference signal stops the second I disconnect the H-field antenna.

(I do not currently have E-field set up but I will shortly.)

Anyhow, it seems that if I have the H-field antenna a certain level low to the ground, the burst mode interference begins;  if I elevate it too much, the burst mode interference begins as well.  For now I have it at a 'medium point' where it doesn't seem to detect this interference, (which honestly is about 5 feet off the ground) - but it seems that detection is very low.

Is there anything obvious here I'm doing wrong?  If the ferrite rod leads come close to eachother in my (pvc pipe) H-field frame, is that going to cause a problem? Did I need to solder the jumper pads?  Is the knot anything more than an indicator? 

Sorry for all the questions, I spent a very long time waiting to become part of the Blitzortung project so I am very motivated to get my station working well... just of course there is going to be a learning curve here.

Thanks,
Michi
