you havent even said if you have been withing receiving earshot of that
1 - you need to know if it is NXDN4800 or NXDN9600 (the number refers to the baud)
2- you need to know if it is simplex , repeater or what ?
3- you need to know the Talk group (tg) as it was programmed and the RAN if applicable
looks like its a trunk system
South Plains Electric Cooperative (IDAS) Trunking System Profile
www.radioreference.com
looks like its missing info (LCN) control channel etc
you can take from sentinel (as its in the database) and program in or if it where me I would program each site as a separate site but possibly you need to know if each fx fits into a LCN that the scanner allows to trunk track
you have your work cut out for you but there are many hear that can help
