Re: [IRCA] RF-Space SDR-IQ

["Guy Atkins" <dx@xxxxxxxxxxxxx>]

Good point, Mauno, about using a traditional radio and SDR-IQ in that
manner. I've mentioned to other DXers about this method, and that it is
probably the best way to go. The SpectraVue software impresses me as a very
nice program of instrumentation (great at data collection, but not
necessarily tuning around the band).

Indeed, spectrum recording/playback features of PowerSDR, in Flex-Radio's
official versions, are lacking in basic controls. I would like to see "fast
forward" and "reverse" buttons (or a slider like in RecAll Pro) that would
allow me to quickly advance to a different point in time in the recording.
One of the amateur radio developers, K2OX, has his own PowerSDR version
available to all, which features improved recording/playback controls.
However, I'm not sure if it includes all the other updates and improvements
made to PowerSDR over the last few months. That's the beauty of an open
source SDR software, in that individuals are free to modify the radio's
features and even performance to their liking. I don't have any talent with
software to do this, but I enjoy using the various versions and regularly
added new features.

Why don't people here consider more the third alternative for the transition

period: using both the conventional and SDR rx? SDR-IQ with Spectravue is 
relatively cheap (and takes minimum space on the desk!), so one can still 
keep also the conventional receiver. Spectravue is admittedly (still) 
cumbersome in real time listening, but it works fine with playback of the 
190 kHz span recordings. In that respect some say it is handier than Power 
SDR? So I use AR-7030+ for real time DXing and SDR-IQ ONLY for 190 kHz 
recording and playback.
