I've wound my loops, and found the wiring diagram for the preamp at https://docs.lightningmaps.org/hardware/...tors/mini/.

Is proper for me to simply hook up my two unshielded loops to H1+, H1-, and H2+,H2-, respectively, without any soldering on the preamp board?
A screw-connection header is already soldered to the board.

Other preamp instructions indicate that pairs of solder pads on the back of the board are to be bridged if an air-core loop antenna is used.
The solder pads appear to be present on the 23.1 preamp board, but no mention is made in the instructions about bridging them.


(I'm not posting from the account I registered when I got the URL from booting up Blue Mini on my home network: I'm pretty sure I know how I broke it and I can't fix it in the short term:  I am dellel, station 3147, if my bone fides are required to get an answer).

I spent the day getting set up: debugging the connection to the very economical Bingfu GPS active antenna, 
www.amazon.com/Bingfu-Waterproof-Navigation-Connector-Tracking/dp/B07R7RC96G
The baud rate turned out to be pretty important for the 1 Hz GPS signal: anything less than 460800 would fail to lock it, 
and a view of the overhead sky is best for it: a south window simply would not do.

thanks for reading

Hi, ive already ordered and had boards for system red. But i'm new to radio engineering. I found a well understood partlist for system blue in docs.lightningmaps.org/hardware/lightning-detectors/hardware_reference/
Do someone have the same look partlist but for System Red?

When I try to access the download site for system red firmware (http://tracker.blitzortung.org/firmware) I get an 404 error (even after login). Could anyone please check?

Thanks.

Hi it appears that the format of https://data.blitzortung.org/Data/Protec...s1.json.gz changed recently.

Previously it contained in addition to other fields:
  - all
  - member
  - valid
  - used

Now it contains:
  - total
  - valid
  - involved
  - used

Is there documentation of this change somewhere?

Thanks,
Ken

I've seen several H-field orthagonal loop antennas using copper tubing on the forum.

How is the loop wire put inside the copper tubing?  What gauge wire?  How many turns?

Details would be appreciated!

Hi all,

I’ve been experimenting with a more compact H-field loop antenna setup for my station — mainly because I’m in a pretty noisy urban area with limited space on the roof. Switching to a twisted pair loop with a ferrite-loaded core has actually cut down some of the EMI for me, maybe by around 30% compared to my old open loop.

I also tried putting the preamp in a grounded metal box, and that definitely helped a bit more.

Curious if anyone else here is dealing with tight spaces or lots of RFI?
Thanks in advance!

Blitzortung Community:

I ran into an unexpected problem today.  While trying to fine tune gain and threshold settings I lost the ability to log into the user interface of my System Blue controller using edge.
Station ID: 2110
Controller:  19.3
I have FW version 11.0b3

I lost the ability to log into the controller after a system blue reboot.
Anyone seen this behavior before?

The address I was using stored in my favorites was "http://192.168.1.110/index.cgi?action=status    

Trying to log in I get this message on my Edge Brouser and Firefox Brouser:
192.168.1.111 


After trying several times and getting confused... I rebooted manual system blue with the on off switch.  No Luck.
Then rebooted the router.  No luck.

Checked the IP address of System Blue on my LINKSYS router.  I could not find Blitzortung, so I performed a clear network map and another reboot of the router.

This time the router saw Blitzortung (new address  192.168.1.111).  Tried that.  No Luck.

Pinged address from a command window and got the following response:

C:\Users\Owner>ping 192.168.1.111 refused to connect

Does anyone have an idea of what my next step might be to resolve this problem?

I read on chat GPT an option to do the following (Steps 4 and 5 below) , but I do not trust it unless there is documentation from Blitzortung with specific instructions and it is the recommended next step.
I hope an expert on the forum can recommend the correct next steps, and if they are complex references to needed documentation, or another thread that explains the next steps in detail.


From Chat GPT:
4. Force a Factory Reset (if needed)
If all else fails, your controller’s web server might have misconfigured settings or crashed.

• Hold down the reset button on the System Blue controller (you may need a paperclip) for 10–15 seconds during power-up.
  
• This should restore default network settings (DHCP enabled).
  

• Connect to the controller via USB and use the Blitzortung update tool from their site.
  
• This lets you reflash or repair the firmware manually.
  

Way back, when System Red was all the rage I expressed my interested in becoming a node operator but could never seem to find out how to get a detector system. Green came and went as did Blue and now I see that we have Blue Basic. 

I've never found a way to order before and I cannot find a way now. I have, once again, registered my interest in giving one of these detectors a home in the far north west of England, where detectors are few and far between. I have all the technical competence and more to build and run a system. I even have an SMD workstation and flow soldering oven, so I could work with a bare board if necessary. I live in an electrically quiet rural location with low latency, fast broadband. 

It must, surely, be possible to get one of these systems but the question is... HOW?

Hello,

As in the topic what's next for www.lightningmaps.org? Is it possible to restore this service to full functionality and update the data, and if that's impossible then it should be disabled because I don't think it provides real station locations. By the way, I've always really liked this map and the way the data is presented on this service. Maybe I could rebuild this database after contacting the developer.
