  I noticed on Hartmut Wolff's grabber similar fading as you have demonstrated.  One of 
the most noticed characteristics of the 137 QRSS segment is that compared to the 74.322 
segment, the 137.777 + and - frequencies are very "dirty" with multiple Loran 
artifacts, I presume are from Eastern Europe and Russia?


Bob,
the main reason for the multiple Loran artifacts is DCF39. Most the time DCF39 is looking like here:

But sometimes like here:

In the screenshot from my grabber you posted here in the list, the activity from DCF39 is well visible about 03:15-04:45.
