I am glad to report that EbNaut signal DK7FC at February 10, 2017 06:00 UTC, frequency 8270.1 Hz, was successfully rcvd and decoded by RN3AUS. QRB=1900 km.
TX: 700 mA antenna current
RX: E-probe MidiWhip and NMEA+1PPS GPS disciplined sound card with SpecLab.
It is first message from DL to RU on VLF Dreamers Band!My congratulation to Stefan!
Also this result would not be possible without very useful councils and utilities of Markus DF6NM, the wonderful SpecLab program of Wolfgang DL4YHF and absolutely fantastic EbNaut of Paul Nicholson. My deepest respect!
