Visualising HF Propagation

Mike Clarke VP8DMH, at the Halley Research Station, Antarctica, has been using WSPR and video to produce a simple visualisation of HF propagation.

He's been running WSPR using my FT-817 at 5W connected to one of the base antennas; running on each band of interest for just over 24 hours.
A relatively straightforward Perl script then automates the process of merging the database downloaded from wsprnet.org into a single 'virtual' day and creating the video:
