Can someone point me in the direction of:

• Where (geographically) would you expect the greatest improvement of accuracy (closer to the new detector)?
  
• Is there an explicit measure of error that would be expected to improve and where in the dataset would I find that?
  

Thanks.]]>

I do have some interference from a solar inverter during the day, but the station was working ok.

Station 18, green pcb 6.8
Thank you.

Looks like my p/s for my system blue is starting to die as it's only putting out 4v. I was going to get another powerstream one (https://www.powerstream.com/AC-1898.htm), but I'm not going to pay $70US (!) for postage to Australia.
So, can any Aussies on here point me to some alternatives??

Thanks,

A device costing €200-300 is probably not “cheap” for many countries. This will not contribute to the development of the project.
By the way, the project website looks a little unfriendly or abandoned. I can't find the price for the “system mini” kit. The data looks scattered or incomplete, as if it was collected in a hurry.

"The World Meteorological Organization (WMO) has established a new world record for the longest lightning flash – an incredible 829 km (515 miles) in a notorious storm hotspot in the United States of America."

"The megaflash occurred in October 2017, during a major thunderstorm complex. It extended from eastern Texas to near Kansas City - equivalent to the distance between Paris and Venice in Europe."

The original article can be read here: https://wmo.int/news/media-centre/wmo-ce...record-usa

Enjoy!

Update:

Original publication introduction:

"Lightning is viewed as a localized hazard to the general public, with safety guidance implying
being close enough to the thunderstorm to hear or see lightning (Cooper, 2012). Lightning
“megaflashes” (Lyons et al. 2019) challenge this view as single continuous long horizontal
flashes that extend for hundreds of kilometers through the clouds, initiating up to hundreds of
Cloud-to-Ground (CG) strokes along their paths. Moreover, megaflashes occur in regions of
organized storm systems that might seem inactive with 30 minutes or longer passing between
flashes (Peterson and Stano 2021). They are also known to produce noteworthy effects –
including potentially damaging high peak current CG strokes with continuing current, and
dazzling sprites above the cloud-top."

I have the mini version at home and works nicely.
But I am also as Hamradio transmitting on 136 kHz 474 kHz and HF and VHF frequencies. I noticed that this gives a disturbance on the mini receiver.
Is this Harm full for the preamplifier , so I should disconnect the preamplifier  or using band pass filter for the mini or is this ok and the AGC can handle it.
The output power of the transmitters is  max 100 watt.
Thanks

Suppose I want to gather ALL pulses detected over Europe in a certain day.
As far as I understand this means I have to gather the data from AT LEAST folders Strikes_1 and Strikes_18. Strikes_19 appears to be just a mirror of Strikes_18.




However, there are some lighthings over Europe that are coming from the other regions, for example Strikes_3.

Does that mean that the pulses detected in that region (which in theory does not include Europe) also need to be considered? 
Basically I just want to make sure that lighthings saved in every region do not contain duplicate in other regions, which would mean that the only 100% safe way of extracting data from the archive is to consider all regions every time.]]> I'm using the data stored at Data/Protected but I'm struggling to understand whether the Region subsetting is mutually exclusive.

I wonder what might be the best way to optimize performance by removing noise floor?

1. Provide cleaner power supply

2. Shorten twisted pair back to 1 foot and use 20 feet of Cat5 to amp 

3. I have 100 feet of direct burial Cat5 on hand that could run out to a weatherproof enclosure up to 75 feet away from the house.

I seem unable to turn gains up past 10x2 or it goes steady interference.

Any advice would be appreciated.

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.
