You didn't look hard enough. In fact, there isn't just one NPR station in Las Vegas, there are two. In Las Vegas, "NPR" also signifies Nevada Public Radio.
As you scan from the low end of the FM-dial numbers, the first National Public Radio station you come to is News 88.9 KNPR; www.knpr.org. It features the news and talk programming you probably know and like: "Morning Edition" 5-8 am weekdays and "Weekend Edition" 5-9:30 am (followed on Saturday by a half-hour of "Car Talk"); an hour of KNPR'S "State of Nevada"; followed by "Talk of the Nation," "Day to Day," "The World," "Fresh Air," "All Things Considered," and "Marketplace"; then the BBC's "World Service" overnight programming from midnight to 5 am.
Next up on the dial, at 89.7 FM, is KCNV, with 24 hours of classical music; go to www.classical897.org/grid.cfm for the complete schedule.
