NWR channels operating in the range of 162.3625162.5875 MHz (162.4.55 37.5 kHz) have a band spacing of 25 kHz may have bandwidths up to 16 kHz. Simplex - (often used for cross patching to 146.550 MHz. ![]() If possible, leave your CTCSS (PL) decoder in open receive mode. Saving lives is the focus of NOAA Weather Radio All Hazards by providing immediate broadcasts of severe weather warnings and civil emergency messages and giving those in harm’s way critical lead time to respond and remain safe.īroadcasts of tornado warnings, flood warnings, AMBER Alerts for child abductions,chemical spill messages and many other notifications, in addition to routine weather observations and forecasts, make NOAA Weather Radio an essential item for every home, business and public area.
