Betreff: Re: VLF: 8270 Hz BPSK

I searched for the message using start times
between 11:00:00.0 and 11:00:02.0 but nothing decoded.

The earlier carrier had S/N 11.7 dB compared with
the 14.7 dB you had in November. Hopefully the S/N
improves from 11:00 onwards. It will be lucky
to decode at 11.7 dB with symbol length 10 seconds.

I am getting some reference carrier extraction
with a symbol timing offset of about 4 seconds, if I scan
from about 10:30 onwards. Maybe the start time is
something like 10:??:?4.0

I'll try 10:30:04.0, 10:40:04.0, 10:50:04.0 ...
