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?

  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.

  Ferrite, leads
Posted by: de37421 - 2018-09-11, 18:21 - Forum: Hardware, Software, Lightning Physics - Replies (3)

I am new, I just got the blue kit.

The ferrite antenna has two bare copper wires.  One wire has an overhand knot, I assume it is to signify that wire is different from the non knotted wire.
Does it make any difference which wire goes to solder pad +1 and which goes to solder pad -1? I read elsewhere that the loop antennas can be attached either way so I think these probably don't matter either.

Concerning the GPS antenna, does it make any difference whether the antenna is amplified or not?  I have ordered one with 25db gain.  https://www.amazon.com/gp/product/B01KDH...UTF8&psc=1
but it is inexpensive and I can get another if preferable.

  Am I a good candidate?
Posted by: jchonig - 2018-09-02, 13:17 - Forum: General Discussion - Replies (5)

I received my invitation for a System Blue and am doing my homework.  I live in the Finger Lakes region of New York State.

I am 3km from antenna towers broadcasting on 1160kHz at 5000W, is that an issue?

My house and pasture is surrounded by electric fence for sheep and dogs, closest it comes to the house is about 15-20m.  I get arching when wires touch and when vegatation grows onto the fence.  Will I be able to compensate for interference this close and still be a useful contributor?

  How to Pay with Paypal?
Posted by: k2ors - 2018-09-01, 22:28 - Forum: General Discussion - Replies (1)

Hello the list,
       I received an invitation yesterday to buy a system blue and would like to order using PayPal.
Can anyone give me the instructions on how to pay? I need to know what email or Paypal user i.d. to send the payment to.

Thank you
