SKYWARN Net Operation

Skywarn nets will be initiated whenever Severe Weather warnings are issued for Southern Dupage or Northern Will County in IL.  Nets may begin prior to our coverage area being warned if the threat is imminent.  

Primary operations on the K9BAR repeater system:

VHF 2-meters: 147.330 MHz, + 600 kHz offset, 107.2 Hz PL tone

UHF 70-centimeters: 443.525 MHz, +5 MHz offset, 114.8 Hz PL tone



These repeaters are cross-linked for transmit and receive operation.

Should it be necessary, our alternate repeater is N9ATO located in Homer Glen, on 443.900 MHz, + offset, PL tone 114.8 Hz.


 

You do not need to be a trained spotter to check into the net. The Net Control Operator will broadcast check-in and check-out procedures.

SKYWARN Net is held every Thursday Night during the months of March thru September and on the first Thursday of the month beginning in October thru February, always at 8:30 PM, or immediately following the Weekly Information Net, on this K9BAR repeater.
