Hearing WXM41

Any receiver that tunes 162.425 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 South Dakota transmitter, county and SAME code: NOAA Weather Radio in South Dakota. Or look any county up with the finder.
