Bad Transformer?
#24

Ok, what I've done now is to use contact cleaner on my band selector and the push buttons and I turned it back on and walla, I'm able to hear a station on the AM!!!! I couldn't tune in anything on the police band, but did get something on the SW. It works, i'm kinda surprised that i'd get anything out of it. Very cool!!

Now that I have a station coming through, I tuned it in and I hear what it sounds like wind blowing. The kind you'd hear from an old movie. Any ideas on that?

I'm still going through the radio and checking all my circuits and learning a lot as I go. There were a lot of things I didn't know when taking measurements. Ohm readings with the power off sure helped. I have a question on taking ohm readings from different parts. Should I get a reading if I put my test probes on either side of a capacitor or resister? Does it matter if it's wired in or not? If I had a loose one and I connected the leads, should I get a reading? Sometimes I don't get a reading when I put the probes on either side of the posts that a capacitor is connected to. I have several places in the radio where this happens, I'm not sure what to think. Could there be too much solder on the posts? Could the part be dead? If it's dead, how many dead parts can you have and still tune in stations?

Thanks for everyone's help so far!

-Jeff
