This from Brad Steinweg:
I have come across a few articles on the page regarding Lake County (IN) switching to a consolidated channel. I have gotten the frequencies for these channels. There are 2 channels that do the dispatching; 154.815 and 154.445, however I have received more traffic over 154.815 so I’m unsure if the second frequency is a backup. For MABAS incidents they use the IFERN frequency 154.265. I believe Hammond and Gary may have private channels, as I have not picked up any traffic from them.
