Unidens are pre-programmed with system ids from the RR database. I guess Harrison Co was the first site so that's what Uniden programmed it to display when it detects the "170" system ID. The only problem with this is there are completely different systems with identical system IDs.
One case is these two systems. http://www.radioreference.com/apps/db/?sid=3958

The LA site was the first one Uniden knew about, so as a result when I tune in the JNCR site it displays "Los Angeles Util".
I hadn't posted since then because of this. I figured it was something along these lines. I figured it was best left alone.
