On some specially built radio receivers, a warning alarm feature is included. When warnings for threatening severe weather are issued, a warning alarm is activated from the broadcast facilities. Radio receivers with the warning alarm feature will sound an alarm to alert the listener to the warning message. Besides weather related events, dam breaks, nuclear accidents, or other hazardous events are also included on the list of warnings that could activate the alarm system. Hand held programmable King radios issued by some of the user agencies have the capability of receiving these broadcasts.
Intermittent reception is possible in many surrounding mountainous areas.
Since VHF radio waves propagate roughly along line of sight, reception to the lee side of hills or other obstacles may be reduced. An external antenna may improve reception, especially at longer distances from the transmitter. National Weather Service 1945 Beechcraft Ave.
