Central Indiana Skywarn uses repeaters maintained by the Indianapolis/Carmel Experimenters.
The main repeater in the Skywarn radio network is the 146.970 MHz (-600kHz, 77.0 Hz tone required during net operation) system located in Indianapolis. The controller in this repeater provides for connecting the entire system together. This repeater is linked to the 442.650 MHz (+5 MHz, 77.0 Hz tone required during net operation) repeater located at a different site in Indy to allow for coverage on both 2 meters and the 440 band from Central Indiana. Each repeater provides slightly different coverage areas due to their locations, antenna height, and antenna mounting location on the towers.
After both of the repeaters are connected in Indianapolis, the network is then connected to the 147.435 MHz Simplex (77.0 Hz tone required) remote link package located in Freetown, Indiana, in Jackson Co. in South Central Indiana. This package helps to provide better coverage from the southern counties in the Indianapolis NWS County Warning Area.
Now to insure better coverage for the Skywarn net operation, the 444.350 MHz (+5 MHz) repeater in Terre Haute, Indiana, (operated by Illiana Skywarn group) is connected into the network. With the addition of this repeater into the network, coverage from the western counties in Indiana and beyond into Illinois for net operation is made much easier.
Next the 443.775 MHz (+5.0 MHz, 88.5 Hz tone required during net operation) repeater in Lafayette, Indiana, is added to the network to also improve the coverage of the Skywarn Network into the northwestern counties in the coverage area. This system will also provide coverage beyond Tippecanoe and Warren counties into northwest Indiana.
