um, two questions:

What is SAME?

Is there a difference between SAME and the NOAA frequencies? If so what is it?

FWIW, there are two NOAA frequencies covering our county. One is in town, 10 miles away. The other is in another town located a bit further away and closer to the border to another state, but is still within about 20 to 30 miles. I know a lot can be different within those distances weather-wise, but it's usually pretty consistently the same in our area.
