County Coverage Listings by State and for Marine Zones


NWR service to a county and marine areas 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 will be so indicated. Some counties or parts thereof, especially in mountainous areas, that are listed as having NWR coverage, may not have reliable reception in some locations due to signal blockages and/or excessive distance from the transmitter.


You may go directly to your corresponding state or territory below and locate your county name and Specific Area Message Encoding (SAME) code; NWR transmitter frequency, call sign and power; and coverage remarks (if any.) A description of columns in the state tables is available. SAME codes for coastal and near shore marine zones are designated. The code listings for marine zones are provided in the marine section of the table below.
