Use a local weather channel to verify that you are hearing the broadcast clearly and without distortion. If you can, switch to a weaker, more distant weather channel to test your radio receiver's ability to hear weaker signals.
Remove the connector on the antenna cable from the back of your radio. Insert the tip of a small screwdriver or paper clip into the center contact of the radio's antenna jack while monitoring your local weather channel. If you can hear the weather broadcast, your radio most likely has good reception.
