Here's a wav from the DL0AO cardioid: http://df6nm.bplaced.net/VLF/fec_tests/dl0ao_6k47_06101811.wav

Start offset accounting for ~ 26 s latency so should be around 2702 s. I can generate a rawsyms plot here, but have to leave the decode attempt to someone else with a bigger machine.

Hi VLF,

Since 21 UTC a carrier is running at 6470.005 Hz. At 4 UTC, a new EbNaut message starts. Let's see if someone can deocde it:

f = 6470.100000 Hz
Start time: 10.Jun.2017   04:00:00 UTC
Symbol period: 20 s
Characters: 100
CRC bits: 8
Coding 8K21A
Duration: 27h, 54m, 40s
Antenna current: ~ 460 mA


73, Stefan
