Hi folks
Is there somewhere a detailled manual/description available for the controller interface (Blue system)? 
Examples: What is meant by Error "Overflow"   or what does the parameter "HP on" flag in the amplifier section mean   ?
Thanks for any clearing up hints.

I have system blue pcb 19.3

Is there any guidance on the order of gains? 

2x32 is the same as 32x2 but I suspect there may be a preferred order? 

Like wise 1x16 or 4x4? 

Thanks

Hello
When I compare the network statistics with th station list statistics, I observce significant discrepancies between the number of signals, strokes and efficiency percentage figures displayed! Do all these webpages use the same data basics and the same time periods for the statistical data? What else could be a reason for the significant gaps? Thx for an explanation.

I have just finished building my new system blue. When I fired it up, the GPS worked but kept dropping out. Now it has stopped working at all. The only way I can get it to work is to power down for a good while and then power it up again. This enables it to work for a few minutes and then it shuts down again. Seems like a heat related problem, a dry joint maybe?
Can anyone help me to diagnose this please?
(I cant search for GPS in the forum because searching for three letter words is prohibited.)

I have just gotten the gorgeous aluminum case for my Blue circuit board.  Having installed all the parts I was very impressed with the precision of the machining and how nicely everything fits.

Then I got a couple spade connectors and some jumpers from an Arduino board to replace the shorting plug on the board to allow me to wire in the on/off switch that is on the back panel.

I cannot see how there is enough room for me to put any sort of wires from the switch to the two terminals that control power to the board.

While I cannot see a time that I might use the switch very much, and I can always unplug the power supply, I'm wondering if anyone who has purchased the enclosre has been able to gracefully wire in the on off switch?

Greetings,

On the system blue 19.3 & 8.3b2 controller signal page I see these letters
"S, L, & L P" sometimes being written just to the right of the 1A and 1B channel rows.

I have searched but have not found any information on their meaning.
What are the meanings of these letters? 

Thank you.

Hi all, for a while I have been considering how to use the Blitzorg data to do a statistical analysis for scientific research. It seems like there are complications in downloading and using the actual data, around server load, licences, data volume, cost etc. For a climatological analysis, having the raw data is not really necessary, but a summary gridded product would be excellent! I think it would also negate the worries the Blitzorg team have about allowing open access to the raw historical data.

Is it possible for you (or us - I am happy to help ) to create a gridded summary product, something like 0.25 degree resolution, 1 hour summary, in an open standard format (NetCDF: http://www.unidata.ucar.edu/software/netcdf/). For each pixel (area bin) the climate community would need to have lightning strike counts, and a measure of aggregated error regarding the detections.

Would you be open to creating such a product? It could potentially be invaluable to the climate community, and widely shared for research. I am sure that NCEP/NCAR and similar organisations would also happily host the data as they do with many others (http://www.esrl.noaa.gov/psd/data/gridded/) so that there would be no load on your servers. Potentially, you could also release the data after a first high-impact publication and garner more awareness of Blitzorg. 

Assembly instructions linked from http://en.blitzortung.org/cover_your_area.php
say to put the 2 (or maybe 3) ferrites at 90 degrees.

The picture on the same page http://en.blitzortung.org/cover_your_area.php
shows the ferrites in a 120 degree delta

What should I do?
Have I missed some documentation/description somewhere ?

thanks

The pre-wound ferrites that came with my Blue kit all have a small loose knot tied in one of the two wires.

What is the significance of this?
Should this be connected to a certain pin of the pre-amp?

thanks

Can the H-field pre-amplifier PCB be placed 'inside' the loops of a 3-loop H-field antenna?
