Pulled out my antenna cord. Now what?

Thanks, everyone. I was able to repair the old plug using your recommendations. My tiny little code R-11 two watt factory AM radio is working like a champ now. Fired it up and the first song that came on my favorite AM seventies station (WDGY 740 on your dial here in Minneapolis) was "Play That Funky Music White Boy" by the fabulously talented group Wild Cherry. Clearly, this song shows why the zenith of music and culture was the 1970s. Cheers, all!
