I'm still in need of some guidance on this. Here is some more info in case someone can help me out. This all pertains to the AM band, but I get nothing on short wave or FM either.
The AM oscillator is running. Here is a scope image (10v/div):
When I tune up and down the dial, there is nothing except some slight hum when the volume is most of the way up, except one spot very low on the band. At that spot I get some static that sounds very much like I'd expect to hear from a radio that is not receiving a station. Here are two scope images. The first was taken when tuned to the static spot (1v/div), the other was taken when tuned to the middle of the dial (0.1v/div).
And here is where I took those images.
Can someone give me some guidance and point me in the right direction?
Thanks,
Rich
