Very nice Domenico.  It is always fascinating to see a message
come out of the noise.  In fact it would still have 90% chance
of decoding if it was 4dB weaker, and 45% if 5dB weaker.

Much to be done at LF with coherent signalling.

Here, just testing a new VLF E-field receiver/antenna with
improved performance.  Its response extends to 137 kHz and
has noise floor 6nV/m in 1Hz at that frequency.
