John Nebl, N9MYC, has created an ICS-217a Resource Worksheet form showing the primary 2 meter and 70 cm amateur repeaters in the state. The list is sorted by district and then by counties within each district. A coverage map for the Central Illinois Linked Repeater System is included, along with a state map showing the districts and counties. This is a work in progress, so information may be revised on an on-going basis.
Many thanks to John for collecting and assembling this information!
