Gram 2.3, a freeware (Win 3.1x, 95) program by R.S. Horne was used to make the spectrograms of the above sound files. This program may be downloaded from this URL:
GRAM23.ZIP
Gram 4.2 for Windows 32-bit version - vastly improved! You can change many parameters to enahce spectrograms. Works with .WAV files only. Outputs in .BMP format. PC-only. Works great with my NT 4.0 SP-6 system.
For other natural VLF radio sound files I recorded between 1991 and 1995, please go to the University of Iowa Plasma Wave Group Web site to hear more McGreevy Ground-Based VLF Recordings from 1991 to 1995, and also one of my best June 1996 Alberta recordings recorded via my WR-4B van-based receiver.
McGreevy BBB-4b Bare-Bones Basic (but great!) whip receiver you can build yourself to listen live to natural radio.
