The WRTH 2011 has a glowing review of this radio, the WinRadio
Excalibur. It sounds like first consumer-class software-defined
blackbox radio to finally get most everything right. Anyone here have
any experience with this radio? IT looks mighty attractive...

I have a Perseus which is very similar in specs. The best thing about
these radios are the filters which are truly brick wall. The bad thing
is that you have to boot up the computer and update it. But, once you
have the computer running there are many benefits. Like constant
readout of the station on freq., running decoding programs like MMSSTV
in the background, recording a big chunk of spectrum on the HD for
later playback, and excellent noise reduction.

I use a dedicated laptop to run the SDR and have had no problems
running multiple programs using Virtual Audio Cable to connect them
together. In fact, I got a perfect SSTV picture from Wolverine Radio
last night with MMSSTV set to Auto and running in the background along
with the SDR.

BTW Channel Z Radio is on 6925kHz AM right now2148 UTC

They aren't real filters at all on the Winradio. The Perseus has front
end bandpass filters. A DSP bandpass filter does nothing for close-in
intermod; not like a crystal lattice roofing filter.

I think WinRadio still has an improved version on the drawing board:

added features:
4 MHz instantaneous processing bandwidth
Low-noise preamplifier
Configurable preselection filters

Att Cuhulin: (pirate) Blue Ridge Radio on 6925kHz USB with bluegrass
music @ 2217UTC.
