Question about station signal quality and too many pulses |

Hi everyone,
I’ve recently set up my Blitzortung station, and it seems to be working fine overall, but I keep noticing that my station often shows “too many pulses” and gets flagged with poor signal quality on the LightningMaps status page.
A few things I’m unsure about: - Is this usually caused by incorrect antenna placement (too much local noise), or could it be a configuration issue in the controller?
- Would adjusting the gain settings help reduce the number of invalid pulses without missing actual strikes?
- Is there a recommended way to identify the main source of local interference?
I’m still learning how to properly tune the station, so any tips or examples from experienced users would be very helpful.
Thanks in advance!

Cheap hardware alternatives? |

Hello!
Are there any designs with inexpensive components, such as ESP32, GPS module, and some other modules from AliExpress? There is an SI4732 chip, a digital CMOS AM/FM/SW/LW/RDS radio receiver. Perhaps something else.
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. It's a cool global project, but it seems unfinished.

WMO certifies megaflash lightning record in USA |

31 July 2025
"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."

Are there any hams on this sub who are involved with the lightning project "Blitzortu |

My question is: are there any hams that are involved with this system to receive and report lightning strikes, anywhere in the world. Is the board difficult to populate, and does it require any surface mount components? What about the receiving antenna...I see a lot of variations and wonder which type has shown the best success. My QTH is only two miles west of the Wasatch Front...part of the Rocky Mountains. I'm at 4400 feet and the mountains go to about 7500 feet, so there is the possibility that I might not be able to "see" lightning to the east of me. Thanks for any advice or ideas. 73 de K7UV

interference with Ham Radio. |

Dear team
I have a question.
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
ok8leo
