SKYWARN storm spotters who are licensed ham radio operators use their radios to report severe weather. If you have a typical police scanner radio (even the old style that no longer picks up Fort Wayne police), you can hear those storm spotters.
In the Fort Wayne area, you can hear the hams by programming the following radio frequency into your scanner: 146.880 MHz.
A word of caution, however: Hams use this channel for normal chit-chat when severe weather is not present. So you might want to “lock out” that channel during those times and enable it as severe weather approaches.
