Runnenfisch, not really enough information to answer your question properly: radio, antenna, terrain, surroundings, etc. Assuming you are within the area of the state served by the NJFFS as linked above, I would suggest you remove any CTCSS that may be programmed into the scanner. Here in DivB I find multiple tones are used on any given frequency. The RRdb is up to date; it is just difficult to detail all the tone variations. HTH.
