True. As I said in another post, I'd love to see someone write an SDR application that captured and quantified such things, but in the absence of that screenshots from a scrolling spectrum display (waterfall) would help. The problem is that you lose the amplitude information when you use the waterfall that is necessary to establish the time correlation between center frequency and spurious crap. With a normal spectrum analyzer that shows amplitude you can't see the correlation in a screenshot.
Maybe it's possible to display a 3D spectrum display! ;) 73, Dave AB7E On 9/14/2012 12:32 PM, Ian White GM3SEK wrote: >> I don't scan the bands >> looking for bad signals because I spend my time contesting instead, but >> I always jot down the callsigns of the really bad signals I find and I >> highlight the worst of them in my 3830 report.
