Priority Scanning
In addition to the 1,000 programmable memory

Weather Alerts
The Federal Communications Commission (FCC)
has allocated channels for use by the National
Oceanic and Atmospheric Administration
(NOAA). NOAA broadcasts Specic Area
Message Encoding (SAME) alerts that include
digitally encoded data about the severity of the
alert.
Regulatory agencies in other countries
have also allocated channels for use by
their weather reporting authorities.
If you program a weather channel as the Priority
channel, your scanner can detect the 1050 Hz
weather alert tone. All alerts are received (FIPS
settings are ignored), and the scanner stays on
