NOAA weather channels for CHIRP
The seven NOAA Weather Radio frequencies (162.400–162.550 MHz) are in the table below as WX1–WX7, set to receive only. The same frequencies carry Environment Canada’s Weatheradio.
Which one is mine
Each transmitter uses one of the seven frequencies; the nearest one is usually the loudest. With all seven in the radio, a scan finds it.
Before you load it into a radio
The file is for CHIRP, the free programming software — not for the radio itself. CHIRP is what writes the channels to the radio, and CHIRP and the radio decide what they accept; we cannot check that without your radio. Before uploading, download the radio’s current memories in CHIRP and save them as a backup, then look through the channels. Transmitting on some frequencies needs a licence or an approved radio — check the rules where you are. You use the file and program your radio at your own risk.
