Laurence, thanks for the screenshot of that
interesting Doppler spread. Wonder if the width would proportionally scale to
0.5 Hz at LF?
Wolf, the chorus recording is indeed amazing!
Windows Media Player said it was missing a codec, so
I copied the URL to SpecLab's "analyze and play stream" function which
worked fine.
Joe, I happened to snatch a marginal opds
detection from your signal last night:
2014-02-21 03:32:24 VO1NA 4585km
137555.000Hz 2mHz -50.2dBOp 94% 15.6dB
Best 73,

It did.
There was
even a strong audible aurora (chorus) at "baseband" frequencies
here,
received with the VLF E-field antenna at DF0WD :
