I have been doing some frequency research in my area and have a question regarding to the database "Search for FCC License Data" I know in my area a local news station uses 450.3125 Mhz. I did a search through RR for the county and the frequency. I get a "No match found". I did search on the FCC webpage General Menu Reports and I get the license match for the station. It is "KK2971". All information comes back through FCC. I went back to RR and did a FCC License search by call sign and even then, with a valid FCC License, I get back a response "No match Found". Can anyone shed some light on this? I appears that RR search engine does not pick up any of the licenses in the 450-451 mhz range. (RP designator ??)
