Guy,
That is what I have been thinking. I put a lot of thought into buying a
receiver and I want a top of the line one that will beat the R8. The
possibilities of the computer generated receivers in the future are
endless. I see all sorts of softwave improvements that in time will

Thanks for the feedback. I think I will wait awhile for the next

Hi Ptrick,
I have an R8B but haven't made any detailed comprisons of sensitivity or
selectivity between the SDR's and the R8B. The SDR's all have the
advantage of a visual view of the spectrum which allows you to see
various station peaks, spurs, interference etc, and that is why I like
them.
Hi Patrick,
If you're looking for a finished product with good software, but only a
15-20Khz real time spectrum window, I'd recommend the Winradio SDR's.
Both of these units offer a very flexible Spectrum analysis window, but
one that will take several seconds to do a scan. Once the scan is

I don't think the LCD screen would be any problem. I have one and it
