Standard Frequencies

National Weather Frequencies

The NOAA Weather Radio (NWR) service operates on seven frequencies, with different frequencies used in different areas. NOAA Weather Radio works with other Federal agencies, including the Emergency Alert System (EAS), to provide complete weather and emergency information.

162.440 MHz 162.450 MHz 162.475 MHz 162.500 MHz
162.525 MHz 162.550 MHz 163.275 MHz  

Ham Radio Frequencies

Hams are amateur radio operators who use a wide range of frequencies for various non-commercial communication. They often assist local authorities by transmitting emergency information when other communication methods break down. The following chart shows some of the frequencies that Hams use.

Wavelength (Meters) Frequency
10-meter 28.000-29.700 MHz
6-meter 50.000-54.000 MHz
2-meter 144.000-148.000 MHz
70-cm 420.000-450.000 MHz

Citizens Band

CB, or Citizens Band, radios are primarily used for mobile communications between vehicles (mobile units) or individuals (handhelds).

United States Broadcast Bands

In the United States, there are several broadcast bands. The standard AM and FM bands are probably the most well known. There are also four television audio broadcast bands -- the lower three transmit on the VHF band and the fourth transmits on the UHF band.

Frequency Range Allocation

VHF Television 54.0 - 72.0 MHz
VHF Television 76.0 - 88.0 MHz
Standard FM 88.0 - 108.0 MHz
VHF Television 174.0 - 216.0 MHz
UHF Television 470.0 - 805.75 MHz

International Broadcast Bands

Several short-wave bands are allocated for international broadcasting because of the nature of propagation of high frequencies. The bands are sometimes identified according to the approximate wavelength of the signals in meters. Your scanner may receive the 11-meter band, from 25.6 - 26.10 MHz.
