A radio that will use this code

WWG75 alerts are only useful inside a radio you can program the s codes above into. Two that do it, for two different jobs.

At home, always on

Midland WR120B. Mains desk radio with battery backup. Program the SAME code from the table and it stays silent until your county specifically is warned, then wakes you.

Hearing WWG75

Any receiver that tunes 162.400 MHz FM can listen: scanners, VHF ham radios, marine sets, or a software-defined receiver. What those do not do is wake you at 3 a.m. - for that you want a dedicated radio with SAME alerting, covered in the buyer's guide.

Every Hawaii transmitter, county and SAME code: NOAA Weather Radio in Hawaii. Or look any county up with the finder.
