In part, my reason for asking is the following... I am feeding the K3 IF Out into a fast ADC at 192 kHz, followed by a Winloe detector, etc. for panoramic viewing, but despite the 192 kHz sampling frequency I am only getting about 44 kHz TOTAL spectral width. Thus, there seems to be a front-end bandwidth of about +/- ~25 kHz. Is this true? Or am I doing something wrong?
The P3 comes up with a TOTAL spectral width of ~200 kHz. Where does it pick its signal from?
