FFTDSP - See weak signals with your PC and Sound Card !!
FFTDSP is a PC program which can detect weak radio signals in real time. |
- Uses the PC's soundcard and advanced signal processing techniques. |
- Extracts and displays weak signals from the receiver audio. |
The example output screen shows a typical two minute period of moon bounce (EME) operation. Near the top are four "echo" test transmissions. The transmit signal is shown just above 500 Hz and the receive echos at 780 Hz. The first echo was the strongest at just under 20 dB S/N. Starting at 2356z, IK5DCX is shown calling CQ at 700 Hz with a fairly good signal (approx 10 dB S/N). |
