The above thread, in which you replied to, has a sample file for Caldwell County in it that includes NCSHP. You could download the software and take a look at the programming to see a working Caldwell County setup that includes NCSHP.
The short answer to your question is to receive NCSHP for F Troop which covers Caldwell is that you program in the Viper Hibriten tower and add talkgroup IDs for F Troop (52187-52194 and 52229). The reason you need all the those TGIDs is that, even though 52191 is labeled as Caldwell, I don't think it's accurate and have not taken the time to figure out the naming scheme as I normally listen to all of F Troop. It's not uncommon to hear Newton calling Caldwell cars on other TGIDs.
For further information (and a known working setup) I again advise you to download the trial version of Win500 and the file in the above listed thread. It has been confirmed as working by the OP that was having a problem.
