I have that same radio - it's great for weather alerts here int he Hurricane Belt, and for Tornado alerts/warnings too. You set it to your nearest NOAA station, and it gives automatic alerts of any emergency.
Especially good with the ill-fated move to Digital TV.
With the digital signal so quirky - I lose signal for virtually NO reason - the TV will be DEAD in the event of bad weather. Bet on it! The Emergency Broadcast message on telly will NOT work. DIGITAL TV is crap.
GET the radio! It could be a life-saver!
I bought mine for $25 at the local Publix grocery - but be aware - when it goes into warning mode at night - it WILL wake you up!
