[R-390] SDR

[quartz55]

I've already mixed the 455 from the R390A IF down to 12KHz, with a 467KHz oscillator (+7dbm) and an SRA-3 mixer to feed my Soundblaster and running 'Dream' on the computer.  Seems to work pretty much like the SoftRock, without the SoftRock radio. On my 3GHZ Athalon, I do get a bit of delay, and it was nice to see the numbers with the MGC levels in the article.  I haven't done any extensive testing with the setup, but it decoded CW, AM, SSB (both), FM, however I haven't gotten the RDM to work yet.  If anyone else has tried 'Dream', I'd like to compare notes.
