Had a break-through tonight with the SoftRock and now it’s receiving quite well. Sounds pretty damned good too! Doesn’t look like I’m getting mirrored signals either.
I am getting terrible results with SDR# still, but HDSDR seems to be working fine.
Still not done though. Right now it’s only receiving signals on its second bandpass filters. I removed all the toroids and binocular core inductors tonight, re-wound them, sandpapered the enamel off the magnet wire and did strict continuity tests. Apparently the new dedication to quality control made the difference. Unfortunately, this means I will need to put 10 or so back on. Lots of solder-filled holes to clear. Argh.
So I only re-installed the toroids needed to get me on 40 meters so I could check my progress. I will hopefully wrap up the build tomorrow night, and provided everything is cool, I’ll order an enclosure for it.
