Hi - Simon closed his year with a nice present: a new feature of his free SDRC software, controlling many SDRs.
It works on recorded files, and converts them literally in seconds into a complete spectrogram. There you can nicely see the "footprints" of each signal.
Just by mouseclick, you set the receiver to the clicked-to time. It features also a clickable loop to define start and end of playing a channel.
It is esepcially useful to see broadcast stations - check bands over 24 hours, congestion, propagation, sign on and sign off times.
I worked with this new and exiting beast a bit, please see at:
With some screenshots, this should also work as a quick starter.
