[Lowfer] DK7FC in EN90xn

[Michael Sapp]

Doug, Garry & All:  First glimpse of DK7FC capture ghosts in the 0130 
sequence, but no captures until 0430. I had a pretty solid capture onscreen 
at 0330. When that capture failed I checked Meinburg and the jitter numbers 
were a tad high (like >30.0 range) so I did an OS restart. The restart 
lowered the PC timing jitter and I had a capture soon afterwards


First sight of possible DK7FC signal in 0130 and 0200 slots around 137.609

Later captures

Note I also had  some local interference from an unknown neighborhood source 
that seems to come and go.  I might have had a few more captures if it had 
not masked DK7FCs signal at (what I have observed to be) critical points 
like the end of a sequence transmission.

Even so, it was  still a good longwave "trolling" experience for the 
evening....
