A county marked with a note (for example partial coverage) is served for that portion only. Program the six-digit code into your radio's SAME location list - the SAME code guide walks through it, and how alert radios work explains what the radio does with it.

Hearing WWF39

Any receiver that tunes 162.450 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.
