Some counties have two frequency channels. check this URL address to see if you have another frequency channel for your area- http://www.nws.noaa.gov/nwr/indexnw.htm
. If you do, try the other frequency channel for your area.
You may be receiving a poor reception quality because of where the radio is located or the antenna's positioning. First play with the antenna until you get a better reception. If this doesn't help, try moving it to a location near a window or outside room. If this doesn't help, you may have to buy an external antenna from an electronics store and hook it up to your radio. If you still have your WR-100 Owner's Manual, they have a page in there for reception (page 12), and it lists in there their suggested weather radio antenna.
It may not be anything you've done at all. It could be the weather station's transmitter itself. May you should call your local NWS
office and plea your case to them.
