randythomas - the FCC no longer maintains a FCC License Database with updated entries.
Its why Police Call publication no longer exists. that and the Author of Police Call died RIP. however the FCC does produce documents on License approval/Denial or NEW radio scanner devices approved.
Radio Reference is just OK for a free service but is maintained my scanner, HAM and commucations radios Enthusiasts and volunteers. and RR is only as accutate as the volunteers are. FCC frequency no longer published or maintained. you can easily verfify with a Digital Scout frequency counter (easy way) or you can program a Communications Receiver like an ICOM or AOR Digital Radio to go a proper search scan unlike what a scanner can do. or if you have a laptop, you can also verify with a Dual SDR dongle . for ease of portibility , I like my Digital Scout frequency counter, It searches the Entire Spectrum in under 1 second , when it locks on the Scout unit can be set to BEEP, Vibrate or remain Silent (stealth mode), I use a Triband Stubby Antenna as you only want the Tower you are targeting, the Scout is completely Automatic no intervention on your part is needed, you just have a walk around the Target with the Scout on your waist like a pager. you can later review the HIT LOGS and review the entry the Scout made. If you have a Icom R-20 or and AOR 8200 mk III then you can REACT TUNE with them , just not for Trunking.
