Thank you for your reply.
I requested a original blue system 1 year ago with several reminders but without success- therefore I started with my own PCB design- of course I want to add my system to blitzortung network. I would by very proud to be a member....
Because www.sfericsempfang.de not longer exists I also have to build my own VLF antennas - yesterday I got my first ferrits.. 20cm rods (10mm diameter) and I ordered also a winding counter . In the excellent docu of the red system unfortunately there is no instruction which copper enameled wire diameter and loop count is necessary for making a high "Q" and low "L" antenna- in some other forum I have found a suggestion for 0,3mm wire and 630 windings over 10mm ferrit rod- but no manual (direction of winding, polarization, etc)
