      Thanks for the support. FFT may not be the right solution for this. I will start with Tone detection first. I did some math and the Tone to detect lasts about 60msec. The PCB I made has connectors for a daughter board for specific circuitry. So...

      Hi, My current project is an tone decoder. Using the Audio board and FFT libraries works very well, but the speed is much to slow to decode Morse or RTTY signals. I am not very familiar with C language but I think when the FFT1024 library can be...
