I've sent two separate channels of audio from the main and sub-receiver on my SDR-1000 to MixW. It results it two waterfalls, as you'd expect. The first waterfall display had the receiver frequencies displayed, and the second had only the audio offset. It sounded like a good idea, but personally, I found the whole thing too confusing. I'm back to using just one display... de Peter K1PGV
