Why does a radio start at 88.1?

Answer 1

In the USA, the FM stations are licensed to operate on frequencies between 88 MHz

and 108 MHz. That's where they all are on the dial. If you want to listen to FM radio,

that's the whole range that you need.

If you want to receive other things on radio, like foreign broadcast, ham operators,

time and frequency standards, aircraft communications, GPS, cellphone signals,

Bluetooth signals, WiFi signals, satellite radio, garage door openers, satellite TV,

fire trucks, taxis, police, or truckers on CB, then you need a radio that covers

different numbers.
