More on the Softrock Experience…

I am not really that much closer to figuring out why opposite sideband rejection is so poor, but I downloaded a couple of different SDR programs in the hopes that they might provide some diagnostic which might point more at the exact cause. <a href=http://www.dxatlas.com/Rocky/">Rocky still seems to be the best. PowerSDR seemed to work and has many cool features, but also seemed to pop and glitch occasionally. I also tried KGKSDR, which is a nifty program too, but which gave a glitch or two as well. I think the take away from all this is that sound cards suck.

But, a couple of interesting milestones with this: I decoded my first SSB signal with it yesterday (nifty!) and also my first PSK31 signal (Rocky has a built in decoder).

Oh, and I spent some time looking for a new scope. No luck yet.
