Blitzortung.org Order List – System Blue - 9. August 2019
Dear prospective participant of Blitzortung.org,
Here you will find the partlist for the construction of a lightning detector kit, which can be
ordered from us. The lightning detector „System Blue“ is a kit. Some parts still need to be
soldered. You should definitely have some experiences with soldering. If not, the kit should be
assembled by friends of you.
The boards are shipped with pre-installed firmware. Please update the firmware as soon as
possible if a new firmware version is available. For more information about updating the
firmware, see the description and the forum.
You should try to build your own loop antennas. If you do not have the possibillity to place a
coaxial antenna, frame antenna, or loop antenna in your garden you can also use our feritte
rod antennas. If you order ferrite rod antennas, please order two. The antennas are mached
each other. Two ferrite rod antennas are sufficient. A third ferrite rod antenna is mainly used
for experiments or for improving the all-around reception characteristic (3 x 60 degrees).
The LTC1569CS8-7 filter ICs are also mainly used for experiments. You should always try it
first without filter ICs. Be aware that you will need one filter IC per channel. Since the digital
filter ICs are very expensive in Germany, we no longer offer these filter ICs. You can order the
them yourself in China, for example at aliexpress.com. The digital filters allow to filter out a
noise signal with a frequency of 80 kHz or higher. Such interfering signals often exist near
long-wave transmitters.
The detector can also be ordered and operated without a housing.
Additionally, you need an external GPS antenna (SMA Connector, 3,6 Volt), a 5V USB power
supply with mini USB connector, and connection cables.
You find further information about the assembly in the following document.

Blitzortung.org is a community of volunteers with noncommercial interests. We make no
contracts. We design the boards here in Germany and let them prefabricate only with the most
necessary SMD parts, so you have it quite easy to build the board completely. We pack the
boards into a parcel and ship it to you. We do all this just as a favor, there is no extra charge.
Since we are no salesmen, we send no invoices for the material and service (only on
occasional exception, if the users will recover the appropriate amount via official channels).
We can not enclose the invoices we get from our local vendors, because these invoices are for
the parts for several kits.
Regards,
Egon Wanke
