Stefan,

Very nice - thanks for you detailed reception reports for the hours be= tween 00:00 and 06:00 and, of course, the decode at 03:00.

I believe the tests have shown that EbNaut may well be a viable QSO m= ode for LF and that my TX station is working well.
Implementing RX= capability for EbNaut is my next goal.

In the mean= time, do you see a need to continue with further EbNaut Trial transmissions= from my station?  I would be happy to do so but, of course, the hard w= ork is on the RX side so I=E2=80=99ll defer to your suggestions.

00:00 20.64 -18.6 -1.7  
01:00 17.44 -4.3 -4.9

Congrats to that 30 chars message over a > 6000 km distance.
