Rob has sent his wave file coming from the Spectrum Lab= EbNaut recorder

With the help of the linux progra= ms vtwavex i have converted it in the vlfrx-tools native .vt file and i hav= e attempted the decode.

Indeed the only possible d= ecode is Riccardo's transmission of 2108-01-27_23:00 obtained with 0.4s= of time offset

carrier phase: 2.3 deg
carri= er Eb/N0: 3.2 dB
carrier Es/N0: -11.53 dB
carrier S/N: 13.73 dB i= n 496.0 uHz, -19.31 dB in 1Hz, -53.29 dB in 2.5kHz
Then I have investigated on failed decodes on my frequency slot= at that hour.
Knowning the message 'IZ7SLZ' and using th= e signal analysis function of EbNaut I found (with +0.001 Hz of frequency o= ffset):

carrier phase: -113.4
carrier Eb/N0:= -7.2 dB
carrier S/N: 8.09 dB in 595.2 uHz, -24.16 dB in 1Hz, -58.14= dB in 2.5kHz

Maybe >6 dB=C2=A0 are necessa= ry to pass my full callsign in 30 minute of transmission.

Thanks again Rob for the attempt.

T= hanks dear friends Jay and Rob for the your efforts on trying to decode my = small signal.

Is it possible to have from you the = Spectrum Lab raw files with the info needed to convert them (using DF6NM= 9;s program)=C2=A0 in 'wave' format (i.e. sample rate, FFT lenght, = center frequency) or can you share the files already converted in 'wave= ' format ?
I would like to attempt a decode using vlfrx-t= ools: with diagnostic tools -f15 -f16 -M 'IZ7SLZ' i will look for t= he missing dB's.
