What would you like help with? I monitor the Delaware county ERS tower. I haven't noticed any IU TGs that are not already listed. I can get you IDs if needed.
Base 150 is located at Ball Memorial hospital in Muncie, with trucks 150, 151, and 152 (patient transport trucks).
Base 160 is in Hartford City (Blackford county) with truck 160 and 161. 160 provides EMS coverage for Hartford City/Blackford county. 161 is a patient transport truck that is based in Hartford City, yet rarely in Hartford City, other than for crew changes.
Base 170 is in Montpelier (Blackford county) and provides EMS coverage for Montpelier/Blackford county.
Trucks 160 and 170 I've never heard on the ERS system, as they are dispatched and communicate with local FDs via a county-licensed VHF frequency.
If you would like to create a list of 'Base' locations, and truck radio IDs I'll be more than happy to log the radio IDs I see over the weekend.
I don't recall the radio ID for 161 off the top of my head, but I've been watching it over the past week, and it appears to be the same day-after-day, which leads me to believe it is a mobile radio, versus a handheld radio from that days crew.
