Interval Signals Library - Collection of audio clips of foreign radio stations, with identification announcements in various languages, signature tunes and jingles, and of course interval signals

WSJT High Speed Meteorscatter - "Software uses four-tone frequency-shift keying for meteor scatter. WSJT stands for ""Weak Signal communications, by K1JT"", and plans call for the program to include more than one communication mode."

EchoFilter - EchoFilter uses the soundcard of a PC to process income audio signals in real-time. The narrow filter bandwidth allow the extraction signals and sounds from the audio signal that may normally be close to inaudible. It is intended for radio HAMS, hobbyists, researchers, scientists and students in the DSP field.

RX-PSK31 - Easy to use Audio Spectrum and PSK31 decoding program specially designed for SWL's who don't need TX or for anyone who just like to monitor PSK31 or analyse signals. Adjustable DSP and Spectrum settings for audio and frequency spectrum to set for best decoding of PSK31.
