FREQUENCY ADDITIONS: In addition to 162.40, 162.475 and 162.55 MHz, NWS has received 4 additional frequencies for use in NWR. These additional frequencies are 162.425, 162.45, 162.5 and 162.525MHz. With these additional frequencies, we are hopeful that Co-channel interference can be eliminated and expansion of NWR can result, but the net effect will be tighter specifications for NWR receiver selectivity.
IPAWS provides public safety officials with an effective way to alert and warn the public about serious emergencies using the Emergency Alert System (EAS), Wireless Emergency Alerts (WEA), the National Oceanic and Atmospheric Administration (NOAA) Weather Radio, and other public alerting systems from a single interface.

The first two frequencies are used by Canada for marine weather broadcasts. 163.275 MHz was used by the National Weather Service for earlier weather broadcasts and later for internal coordination in the event of a power outage but is no longer in active use.
