FYI, NOAA has been adding numerous tightly-spaced Weather Radio stations all over the country. A few years ago a new station signed on for my area, from Odell, IL. A couple years later, a closer station signed on in Lockport, IL. Then one even closer, Cissna Park, IL. Then, a new station signed on right in Kankakee, IL which is only a few miles away. I moved 15 miles north and now I'm equidistant to 5 different NOAA stations (although the one in Lockport, IL officially serves my area).
About 10 years ago Chicago's 162.55 was the only weather station for 70+ miles.
