Some KSICS towers have some of the KCMO side of MARRS frequencies. Current scanners do not associate the NAC with the system in P25 trunk mode. If you are within reach of the KCMO MARRS towers then your scanner will be scanning KCMO MARRS and probably not the KSICS tower that is listed on the scanner. So the scanner might be displaying KSICS Topeka but it is actually scanning the KCMO MARRS and is picking up on one of their frequencies or control channel. I don't believe the KSICS Olathe, Paola, or Parker towers share any KCMO or CASS MARRS frequencies. FYI if you are scanning with the full database.
