I checked out the Visual Analyser program. Very nice compared to some of the PC scope programs I’ve tried.
However, it appears to be for audio only. The two articles they reference show some type of USB soundcard interface which appears to be for audio frequencies. The op-amp chips, TL082, have a great response for audio but not for RF. They do say the analyser can be used with your PC soundcard which also won’t work at frequencies much above the audio range.
They show a sat dish but it doesn’t appear to have anything to do with the analyser.
