Looking for suggestions on cleaning humming noise from audio file? Filter?

I am looking for suggestions for the best way to use Soundtrack Pro to cleaning humming sound from AM radio recording. Is there one filter or woekflow I should incorporate to do this.

As always thanks in advance for your reply to my Post,

In the waveform display, select the part of the audio file containing only the noise you want to reduce. Choose Process>Set Noise Print. The selected noise is stored as a noise print. Then, in the waveform display, select the part of the audio file in which you want to reduce noise (probably the whole file in your case), and choose Process>Reduce Noise. When the reduce Noise dialog appears, drag the noise threshhold slider to the right just a bit (I take it down to about -45db to -40db), and click the play button in that dialog window to preview the file. If you like what you hear, press Apply.
FYI, this was taken nearly word for word from the Soundtrack Pro user manual, pp168-169.
Happy denoising.
