Unfortunately, the database is full of seldom used frequencies. It's the nature of the beast, especially when it costs little to nothing for public safety to license frequencies and perpetually renew them. It's not unusual for an agency to license multiple frequencies after formulating a grand plan for their usage, only to wind up using them once in a blue moon even if they're programmed in every radio.
As far as the RRDB is concerned, unless there's convincing evidence that a frequency is not capable of being used anymore (i.e. no longer programmed and/or no hardware to support such frequencies), we leave them alone. That's our official policy.
I have no issue with removing dead entries from the RRDB if they can be confirmed per the above criteria. Otherwise, it's best to just leave them be. Users of the database are free to lock out, delete, or simply not program anything they don't care to scan.
See, the thing is, while PJ VAC may only use 46.04 once every couple of years, the minute we remove it from the database and they use it, we'll get complaints that we removed a valid frequency. :roll:
There's a guy in a neighboring state who is always gung ho about getting every entry he feels is no longer useful removed from the RRDB. He's made it his crusade on this site, and frankly, it gets old fast. He seems to believe that the day an agency starts using a trunked system, for example, that they must've completely abandoned all of their conventional frequencies. Those of us who operate in the real world know that's hardly ever the case, and while old frequencies may hardly ever be used, if the potential exists then there's really no harm in leaving them in the database. You never know what might pop up one day that will surprise you. :wink:
