Geographical calls are sent by specially equipped radios to all stations in a particular geographical area to alert only those stations of the call and not stations in unaffected areas. If you are in an area to which a Geographical call is made, it will sound the geographical alarm on your radio and switch your radio to the channel chosen by the sending station.
