Lafayette SKYWARN Repeater System
The Lafayette SKYWARN repeater system is operated by the Lafayette City-Parish Office of Homeland Security and Emergency Preparedness. It transmits on 145.370 MHz from a main transmitter located on top of the Lafayette Parish Courthouse in downtown Lafayette. Access into the repeater is accomplished thru any of the five remote receivers located around the parish. Each remote receiver listens for transmissions on 144.770 MHz but accepts only those that transmit the PL tone for that respective receiver. When a remote receiver hears a transmission with it's specified PL tone, it repeats the transmission to the main repeater on 446.950 MHz. The main repeater then repeats the transmission out on 145.370 MHz.
The Lafayette Parish is segmented into 4 quadrants separated North/South by I-10 and East/West by I-49/US 90. Each of the four remote receivers are designed to provide coverage for one of the parish quadrants. A fifth remote receiver is located at Cajun Field to provide additional coverage to the central area of the City of Lafayette. Each quadrant is also assigned a simplex frequency for use in the event all, or portions, of the repeater system become inoperable.
A map showing the parish quadrants, their assigned simplex frequencies and other EMCOMM repeaters can be viewed at SKYWARN Quadrant Map
