Re: VLF: Carrier on 4470.005 Hz!

Hi Stefan,

think we got it! The most plausible decode "PEACE" came from the DL0AO EW-antenna, whereas the W-cardioid insisted on "@ !&;". Both files ended half an hour early at 18:27, but I was too curious to wait two more hours for the next FFT output.

Best 73,
Markus (DF6NM)

Hi Paul, Markus, VLF,

That's already a nice peak! Markus' 'OK message' came to late last night, so i let the TX running without starting EbNaut. That's not bad at all because now you will get more energy to produce a better peak.
I'm happy with the SNR on these two locations from my first signal between 4...5 kHz.
I'd like to start a somwwhat longer EbNaut message which will be repeated daily until there are decodes on your RX sites. For DL0AO it could work with 1...2 days stacked and for Paul we may need 2...4 days:

f = 4470.005000 Hz
Start time: 22.August.2017  04:00:00 UTC
Symbol period: 60 s
Characters: 5
CRC bits: 6
Coding 16K21A
Duration: 14h56min
Antenna current: 150 mA
(suggested optimum list length: 9)

Great, i'm excited and curious to see if you will get that message :-)

73, Stefan

So far,

About 10.5 dB in the 12 hour integration.
