I would certainly like to try to receive you again on VLF, Stefan. 
But I understand that EbNaut cannot be seen on a spectrogram. Is that 
correct?  I don't have GPS timing (though I expect to have it by the 
New Year). I do have excellent frequency accuracy and the computer 
clock is synched to an NTP server and is kept within 0.5mS.

Is there anything I can receive during this test? Or should I wait 
for a simpler transmission?
