Understand that there are two site maps available for trunked systems on RR:
FCC Callsigns - This site map is automatically created based on the FCC license data. We (the DB Admins) have no control over this, except to make sure the list of call signs for the system is accurate. Beyond that, the map is going to show site locations based on whatever data is contained on the FCC license, which might not be correct or accurate.
Another issue with the FCC Callsigns site map is that some of these statewide 700 MHz systems do not have individual licenses, instead they fall under a blanket SL statewide license that does not list the individual sites. In that case, you're not going to see anything, or you may see an incomplete map of the sites depending on whether regular FCC licenses are mixed into the system also.
RR Locations - This site map is created based off of the coordinates we enter for each site in a system. We have full control over this map, and it could well vary from the FCC Callsigns site map depending on whether there are inaccuracies on the FCC license that we have compensated for (i.e. the incorrect coordinates are listed on the FCC license, which we corrected)
One issue with the RR Locations site map is that simulcast systems/zones will only show a single placemarker, which is generally placed in the geographic center of the simulcast zone. This means that systems that have a single simulcast site composed of multiple subsites are only going to show a single placemarker.
