"WebIn the case of an FM receiver the RF is much higher frequency so an IF of 10.7MHz is normally used. An AM/FM receiver has both 455KHz and 10.7KHz tuned circuits in its IF stages, allowing it to work equally well for both bands. In fact, if you mix two frequencies f1 and f2, you get not only f1 - f2 but also f1 + f2. " - How do am and fm radios work
