- FFTDSP is a PC program which can detect weak
s in real time. Uses the PC's soundcard and advanced signal
processing techniques, extracts and displays weak signal
s from the receiver audio.
- A freeware program to dig out weak signal
s buried in noise, functionally similar to the excellent FFTDSP of AF9Y, but with the added bonus of real time audio filtering of the incoming signal
s. Just point and click with the mouse, and the selected signal
will stand out from the QRM and noise.
