8.97kHz very sensitive spectrogram online

Paul Nicholson in Todmorden, Yorkshire UK has put on line his steerable and highly sensitive spectrogram for the VLF Dreamer's Band around 8.97kHz. Paul's system is super sensitive and detects just about anything going. His new spectrogram can be "steered" to a specific direction and the display clicked to show exact frequency and S/N levels. There is also a roll back function so that records from a few hours to days back can also be checked. Marvellous! See http://abelian.org/vlf/fbins.shtml
