Commercial AM radio stations (in the USA) operate on carrier frequencies spaced every 10 KHz
between 550 KHz and 1.65 MHz.

Commercial FM radio stations operate on carrier frequencies spaced every 200 KHz between
88.1 MHz and 107.9 MHz.

Commercial analog TV used to start at 54 MHz and get 6 MHz for each channel, with gaps for
other services. Since the forced mass exodus to all-digital TV in June '09, I don't know where
the TV's all are now.
