Most interesting,
Tell us more how you did it.
- antenna used?
- daugherboard?
- etc
Many SDR users in Northern Scandinavia are up day and night listening on submarine traffic on VLF.

Some of you know that among my various activities involving the application of radio to space science, I operate a VLF receiver, called
 SIDsuite, that is a Gnu Radio based application.

Today, sunspot group 1302 has been putting on a great show, and I wanted to share the plot of one of the VLF paths I monitor, which is
  strongly affected by solar X-Ray flare activity, due to X-Ray flux changing the refractive index of the ionosphere.
