I've got another update. Now I can't even get AM. I used to get AM, but now I
hear the same static noise that I hear on the Air/Police High/Weather band.
There is also another problem with the radio. It works fine on AC, but when you
try to power it on DC, it's a no go. It takes 4 D batteries. I've cleaned the
contacts, checked the wiring, and still nothing.

This may sound like a lot of trouble for a cheapo radio, but I'd like to learn
about how these work. I've always been curious about that part of it. Also,
once you've unsoldered one end of the capacitor, can you test it with a
multimeter, and if so, on what setting. I have an analog Craftsman multimeter.

Thanks again. :-D
