Hello Bob and Hartmut, <br>
  <br>
My congratulation for that success. Both of you must have a very
suitable system to radiate respectively receive a signal on the 4000m
band! <br>
  <br>
Bob, can you transmit DFCW? If 4000m behaves reasonable like 2200m, then<=

DFCW-180</b> should be a good choice! It is a bit slower and may allow
reception of your signal even for station with lower RX sensitivity
than Hartmut offers. Also DFCW gives you a better ID since the
frequency shift is another indicator which separates your signal from
random QRM...<br>

the capture is a bit tiny, because I used a qrss 120 screen. Your
signal was drifting and you crossed the Loran line just before 04:00.
For the future a frequency 1 Hz lower would be better. <br>
