Crosley 106CP Modulation Hum
#5

I was pretty sure I'd missed something in my restoration until I brought the chassis and speaker back home. I had tested it originally with a random wire test antenna, so I figured maybe there was enough hash and static that I didn't notice the modulation hum. But when I dummied up a loop similar to the Crosley original and it was quiet with no hum, I figured it had to be something at the site.

I'll have him turn off lights and so forth if he has fluorescent lights. Thanks for the tip about chargers. I was wondering if there could be anything wrong with the way the outlet was wired that would make this happen, like if it had a bad ground connection or something. Any thoughts?

But here is one more question. If it were interference at the site, I can't figure out why it would show up as modulation hum instead of humming across the band and not just on as station.
