Final answer:
NOAA weather stations operate on dedicated VHF FM frequencies outside of the commercial FM band (88 to 108 MHz) to broadcast weather information. The listed frequencies from 162.400 MHz to 162.550 MHz are part of this service, and when tuning in, one should select these frequencies on their radio receiver.
Step-by-step explanation:
The frequencies listed (162.400 MHz to 162.550 MHz) are specifically allocated for the National Oceanic and Atmospheric Administration (NOAA) weather radio service, which is a network of radio stations that broadcast continuous weather information directly from the nearest National Weather Service office. These broadcasts operate across the Very High Frequency (VHF) FM band. FM radio waves carry information through frequency modulation, in which the frequency of the carrier wave is varied by the audio signal. The constant amplitude of these FM waves allows for high-fidelity sound transmission, making them suitable for broadcasting music and voice. The specific frequency range for commercial FM radio is between 88 to 108 MHz, which is different from the VHF TV channels that lie in the ranges of 54 to 88 MHz and 174 to 222 MHz, and from the UHF TV channels ranging from 470 to 1000 MHz.
NOAA weather stations transmit on dedicated frequencies outside of the typical commercial FM band, which helps to prevent interference with entertainment broadcasting. When one wishes to tune into a NOAA weather station for updates, they simply select one of the listed frequencies (for example, 162.400 MHz) on a compatible radio receiver.
