Explanation of NWR and SAME

NWR service to a county depends on reliable signal reception, which typically extends in about a 40 mile radius from the transmitter, assuming level terrain. Counties without NWR coverage or partial NWR coverage are indicated. Some counties or parts of counties, especially in mountainous areas, may not have reliable reception due to signal blockages or excessive distance from the transmitter.
