We use a Midland WR300. The main purpose of the S.A.M.E. technology is to filter out alerts from unwanted areas. When we are at home in the Midwest we filter out the counties far to the South of us since the storms through that area rarely effect us.
When we are traveling we just set it "All" and then we get the warnings from the local area. Radio is ALWAYS on at home or in the fiver. In the truck while traveling we have a CB that monitors NOAA frequencies and will sound an alert even when the volume is down.
