I tried taking it of the metal chassis and now the broadcast stations were quiet compared to a loud hum. The hum got more intense if I put my fingers close it the volume control wires. Also if things got moved around a bit it the broadcast stations would get loud and then stop when things moved back around again.

If the stations are heard regardless of your tuning, it is probable that they are being picked up by the audio system. Can you double check that the volume control and the speaker wires don't touch the chassis anywhere?
Ok, so are you talking about getting this http://qrpme.com/?p=product&id=BCI like suggested at http://ubitx.net/fix-bci-filter/ or another one of their suggestions? Or maybe something like in this youtube video https://www.youtube.com/watch?v=fgQenFJOjr4 ? Or did you have something else in mind? I'm all for whichever is simplest/easiest as I am a beginner.

well, yeah. If you have AM stations close by then they can definitely
overwhelm your frontend.
Get one of the bitx AM broadcast filters; they're high-pass filters
that drop-off around 3MHz. So yeah, you won't be receiving 160m, but
that's ok right?

Ah, it looks like both these stations also have AM counterparts, at 1490 kHz and 1210 kHz. Does that change things?
