Hi Des, I left FFTDSP waterfall monitoring 136 for me whilst I had my beauty sleep (at my age I need all I can get!). Your morse was just a little too fast for my settings, which were set for a 3 sec
Actually you don't need full blown specrogram to start up on a timer you just need a program that starts up on a timer and captures a .wav file, which you can then feed into spectrogram at your leasu
