...something went wrong. The transmission stopped :-( I'm continuing 
with a carrier until 23 UTC. Another message attempt will start tomorrow.

Hi VLF, <br>
  <br>
After transmitting carriers for the last 5 days, there are 3 good days
to stack, the others were noisy. <br>
The resulting SNR via start time plot for different carrier length is
attached. With some uncertainty we can say that these days the ideal
start time for the path from DL to VK7 is 17:50 UTC and the message
duration should be between 2.5...3 hours.<br>
  <br>
This evening i'm going to start an attempt for a 2 character EbNaut
message. With some luck, just 2 days, i.e. 2 stacks will be enough to
get a clear decode.<br>
