Monitoring Attack Plan R on CRM-114 Discriminator
Have been researching three of the local NIPSCO sites in ISP District 14 area this week.

It appears the LCN's for the entire system are based on the following equation:

LCN = (FREQ - 934.9875) / 0.0125

This calculation has confirmed to work correctly on the Oakdale Dam, Chase and Monticello sites. It also lines up with several other sites and their LCN's listed in the database.

JUST A REMINDER- as has been mentioned previously - there are some discrepancies between what the FCC database lists as licensed frequencies and what are actually used at each site.

I hope this helps out others trying to figure out this system for their local site(s).

If it works for your site(s) of interest, please submit updates to the database.

Thank you

NIPSCO just put up 2 self standing towers in Fowler at the substation, and Chase where their current radio tower is as well, atleast 180ft. Tower in Fowler appears to have 1 microwave dish, and 2 900mhz antennas.
