Hi Stefan,

Question: do you have a realistic guess of the frequency window of your
transmission around 6.5kHz, e.g. +-100Hz?

Distance is 516km, heading 10deg. to Kiel.

Just modified the software running at ~17mHz of resolution. Antennas are
two crossed ferrite loops feeding some BC550 in parallel buffered by
NE5532. Both amplifiers are connected to a M-Audio Audiophile 192 running
at 24 kHz on an Intel Atom 330 "shoe-box" under Linux.
