Jim,
I dont really know when Bob switched off... On my
grabber, the signal dropped sharply around 6 UT, thus the correlation
peak was probably based on the first half of the sequence which ended 6:52.
But on Paul's spectrogram http://abelian.org/vlf/sg29499.shtml
the carrier stayed visible until after 8 UT.

Markus,
This
is a welcome sight. Thanks to you and Bob. Was this detection made approximately
ten minutes before Bob switched off?

Just one detection
here, but that makes it worth the effort:
2014-03-07 06:52:02
WH1XBA 6448km 29499.000Hz 1mHz -52.9dBOp 100%
15.3dB
Out of the last four
nights, this was the one with the highest noise. The carrier was visible
since about 0:30, but the detection occured only in the morning when the noise
went down before the signal did. Unlike Paul in Todmorden, I don't have a
steerable pair of loops, so only the blanker to combat the statics.
Bob, thanks for this
signal!
