Hello groups, To whom it may concern:We plan to make some improvements at the active vertical antenna of our grabber vlf.u01.de . Main objectives are the extension of the lower cut-off frequency down to real ELF and the reduction of noise in the ULF, SLF and ELF range. Therefore the vertical antenna will be out of service for some days, starting at 20190430 1400UTC. The vertical signals will be absent in the exclusive vertical instances as well as in the combined cardioid instances. Our LF- and MF-grabber lf.u01.de will not be affected nor its Opera and EbNaut analyses. Comeback will be announced on the reflectors - or you`ll see it on the grabber screens by yourself ;-) 73, Tom, DK1IS on behalf of the DL0AO team |
