  • Additional Information for Cook County from:
    • Northern Cook Co. Skywarn is a joint effort between members of the North Shore Radio Club, NORA, and Palatine ARES. Severe weather nets take place on the primary 147.345+ MHz (TPL 107.2 Hz) repeater. The NORA 147.09+ MHz (TPL 107.2 Hz) repeater is the backup repeater if 147.345 is down. Spotters may check into this net during severe events. Net control will operate with callsign WX9NC. All severe reports will be relayed from net control to the FISHFAR liaison system as encouraged by the NWS. Reports will be taken from anywhere within the repeaters’ coverage, however, we will actually only activate based on severe weather for Northern Cook County.

Reporting Tips

  • Don’t call in just to “check-in.” This is not a roll call net. Call in if you have a severe event to report, question about the storm, or you need emergency help. If you do not have a notable weather report of interest to the general public, just listen.
  • Don’t call in and say “KC9AAA… I’m on my way to Woodfield Mall and will be monitoring.” No one cares if you are on your way to the mall or where you are unless you have a notable weather report. You may be tying up the frequency unnecessarily just announcing where you are.
  • Don’t call in that your corner sewer is clogged.
  • Don’t ragchew during severe nets. Even casual QSOs are prohibited during severe net
  • Do call net control if an area river is rapidly rising which may cause a road to be washed out.
  • Do call net control if you are bike riding, boating, golfing, your kids are playing outdoor sports, or if you’re part of a marathon team and you would like to know more about the storm’s path or intensity forecasted by the NWS.
  • Do call net control to report property damage, uprooted trees, or large broken branches caused by the severe event.
  • Do report your name/call, location, time, and describe the event.
