Hallo Fabrizio,
your picture looks interessting , but I dont understand, what I can see. The blue line looks like the IF of your reciever. The red one ??? Is it the spektrum showing the frequency shift ?
And the green line at the bottom ????? I dont have any idea.
It looks great , but I need some words . Thanks and regards Klaus

Hi Klaus,
Thank you for your comment.what do you see is the doppler signal of a meteor passing through the signal of Graves radar trasmitting without modulation at 143.50 mhz and captured in Turin with a simple PCR 1500 in CW with an omnidirectional antenna and a high pass filter.all is connected to a 16 bit soundcard and a server.we have finished our meteor scatter station , you can see live spectrograms here http://www.sidmonitor.net/gallery/station.html with already existent VLF spectrum for SiDs. The above images are the elaboration of the wav recorded , using sonic visualizer software. The red yes is the spectrum with a resolution of 256 fft points zoomed in to let clearly visible the doppler signal of the meteor (you can hear the sound too here http://chirb.it/n0Bqnv ) The green line at the bottom is showing the overall progress of the .wav file , one hour in total.

Best Regards

Fabrizio
