In house AM Radio Interference during the day that disappears at night?

OK, so for all of you wondering what kind of radio I'm utilizing that I'm able to pull in all of the stations I mentioned as well as I do, I'm listening to these stations on either my 1985 GE Superadio II or my 1950 Zenith Transoceanic Radio, both radios of which have super sensitive and super selective tuners, I was once actually able to pick up WBAP out of the Dallas/Fort Worth, Texas area on my Zenith Transoceanic and my GE Superadio at night, and that station is over 1000 miles from where I live.
