[Winky Dink]

Update. I hooked up the long indoor antenna, and I do get some reception--weak and jumbled, as if it was desperate for alignment.
Maybe something happened to the RF or IF? Again, I don't know what I'm doing, but I'll see what I can figure out with a signal generator and check all the parts that I think are important in RF/IF detection, mixing, etc. But that will have to wait until tomorrow night.
