Isle of wight one plots the storm 30 miles+ NNE of actual location, its
over dagenham essex as we speak

Yes and the other seems to have similar error in the other direction.
Indicates a calibration problem of some sort but I don't understand
these detectors enought to know what it is.

Believe me they are quite difficult to calibrate correctly, especially
the further the storm is from the detector

Judging by the Met Office's rainfall radar, the Isle of Wight lightning
detector seems to be the more accurate. The Ipswich one seems to make no
sense at all.

Would it not in this day and age, with all this high speed broadband about, be
possible for those of you with these detectors to work together in setting up some
sort of server or web page or summat that would accept the data from all detectors
and use the timings from each report to triangulate on the strike so that it could be
more accurate and also discount spurious reports ?

I shall now catch breath and say - I suggested this a while ago and some comment was
made about it being a good idea...

Just a suggestion don't ask me how it would work, there's plenty of people out there
who'd know how to set it up...

Hi
Well that is already done at the following,
http://www.meteorologica.info/StrikeStar/
but unless you are a contributor like myself I think
you have to pay for the info. Personally I think (i'll get
shot for this) it should be free to all, any advertising, webhosting etc
should contribute to the costs.

As for the accuracy of the individual, calibration does require a bit of
time and patience but reasonable accuracy can be achieved by checking
against met office radar etc and personal siting when storms are very
near. The antenna has to face due North to start with and then you start
calibration from that point, firstly by using the software to adjust the
alignment by setting the amount of degrees off North and then by
constantly checking distance. Eventually you can get reasonable accuracy.

It is a shame that there are quite a lot of inaccuracies around as I do
think it is a useful piece of kit when used at its best.

Purely out of interest, but True North or Magnetic?
