Whenever the threat of severe weather occurs, or the NWS issues a warning or watch for Jackson County, a Skywarn net may be activated. The CARS 146.880 repeater has a dedicated NWS NOAA weather receiver that will trip whenever there is a weather event in Jackson County.  This will be evident by the letter “W” in Morse (Di dah dah) as the courtesy tone on the repeater.

Skywarn nets will be brought up in one of two modes, standby or directed. This decision is up to the person in charge of net control, or by direct order of the NWS, or OEM/EMD.

In standby, trained spotters are encouraged to watch, listen and report. Most likely, NWS has issued a watch for a county and there is a potential for severe weather. While in standby, you are welcome to use the repeater, we ask that you keep your conversations short, and leave long pauses between key-ups, in the event someone should need to make a report.

In a directed net, it is most likely NWS has issued a warning for our county. The net control station will be responsible for collecting reports from spotters and relaying critical weather information to the NWS. During the directed net, only weather related traffic will be allowed on the repeater.
