Hi Stefan, VLF

Many thanks, dear Stefan!
Argh!...I started recording too late, many bits lost :-))
But I'll try anyway...
TU GN!

All the best

Hello Riccardo,

My congrats to your first VLF message decode! I confirm the message is
correct.
You see now that VLF reception is possible from your QTH and you just need
to get less noise on 8270 Hz maybe. But the system and frequency+phase
stability is there! This weekend there may be a chance to pick up something
on 8270...

The night is already a few hours old, so let's try just 4 characters:


*f = 17470.1000 Hz Start time: 05.Dec.2017  21:40:00 UTC Symbol period: 30
s Characters: 4 CRC bits: 16 Coding 16K21A Duration: 08:00 [hh:mm] Antenna
current: 1 A*

73, Stefan

Hi Stefan, Luis, Paul, VLF

this is my decode (the first in VLF).
Very strong here, despite noisy reception.
Stefan, please could you try to send a faster message after sunset,
when SNR of your carrier is much better?
I made some tests whith EbNaut decoder: " ****** " message appear on
your carrier with 2 or 3 sec./sym (with a few +dBs of Eb/N0).

All the best

Hi VLF,

Tomorrow i'm going to gtry to pass a first EbNaut message over to EA5DOM.
Here are the details:

f = 17470.1000 Hz
Start time: 05.Dec.2017  07:00:00 UTC
Symbol period: 120 s
Characters: 1
CRC bits: 6
Coding 8K19A
Duration: 08:00 [hh:mm]
Antenna current: 1 A

73, Stefan
