Hi All
My GPS was working fine, then it stopped. I did unplug it from the box to tidy up the cables. Now nothing. Any suggestions?
Many thanks

I have a ham radio. Yaesu FT-450D. I transmit 100 watts on the 20, 40, 80, and 160 meters ham bands. How should I protect a blue in the same radio shack?

Anak Krakatau: Lightning frenzy points to scale of volcanic plume

So the question. Could these strikes be detected? Is their anything different about them? 

Given a map of volcanoes, could the system be used to detect eruptions and perhaps provide early warnings? 

http://volcano.oregonstate.edu/volcano_table has lat long of some volcanos

Smithsonian has a list of current erruptions

You would expect any lightening to be pretty fixed, even if the wind is blowing. That rules out most moving weather systems.

One problem, being a mountain, they do tend to trigger cu nims anyway.

Hello everybody.
For a long time I was not interested in the connection speed between my router and the device PCB 19.5.
Currently, the connection speed is 10Mb / full duplex and only connects automatically on router side.
All attempts to establish a manual connection to 100Mb / full duplex were unsuccessful.

The question is for those who know whether the device works with a connection speed of 100Mb / full duplex or is it possible a problem on the part of the device?

Thx.

I'm on disability was wondering if anyone would be willing to donate a working unit please feel free to contact me Thank You

For those of us making our own enclosures for the system blue, I have made a piece of artwork that may be useful to some of you for creating a front panel.

Also, I have created a back panel to be made as a PCB, this can be opened using Sprint Layout.

I have a system Green which includes the following:

Main PCB
Amplifier PCB
EM-406A SiRF III GPS module

I'm in the process of switching to the Blue system in the next few weeks.

FREE + postage, it will be going in the recycle bin by June.

NOW SOLD

Many thanks,

Hello,

I am currently developing a new image for the detector data with statistical informtion of the last 4 weeks. The image should help to recognized interference times and other probems.

Here is an exampl of my detector

https://map.blitzortung.org/statistic_1....omposed=10

Parameters are
station
region
minutes_composed
header_line 0/1 switches the heading off / on
header_text 0/1 switches the color explanations on / off
drawing_area_height 1-300 defines the scale height.
weeks 1-4 limits the display to the last weeks
time_zone -11/12 adjust the rtime scaling to local time
background_transparent 0/1 set background color to transparent

Greetings,
Egon

Has it ever been considered to add additional detection of sound to the system, or maybe to have a different (simpler) system that can be used to detect the origin of loud sounds?
As sound travels a lot slower than light, it would likely be sufficient to have an NTP-synced clock instead of a local GPS receiver.  But of course it never hurts to have it.
However, to have useful use of such a detection it needs more stations than the lightning detection system currently has.

Still, much of the basic principles would be the same, so maybe it could be done as an addition or as a second project within Blitzortung.org?

Application: location of the source of explosions, shootings, fireworks etc in a local area.
