Thanks for the info. If that's an Opera signal then maybe my timing system isn't working so bad after all. > Sidebands are from the 8.192 s AM modulation. I see. Hmm, a lot of energy in the carrier! Hopefully there will be some snippets of pure carrier at some point so I can see what the jitter looks like. I just threw together a live spectrogram covering 137500 +/- 25Hz http://abelian.org/live/lf1375.png Updates about every 15 minutes or so. You'll probably have to do shift-refresh to make your browser grab the latest image. I'm recording the whole band but only plotting a 50Hz band. I'll leave this running overnight and see what comes in. Looking forward to decoding messages from Domenico! -- Paul Nicholson --
