He is trying to program a radio for non-affiliate scan, which does care about the Iden tables. Why is asking for these such a source of contention in these forums? Seems just about every time someone asks for them, the posts get filled with "get a scanner" or "run unitrunker on the system". This is not practical for someone who wants to travel to an area and take the time to properly program the radio ahead of time. The other option is to rush and potentially make errors when they arrive.
I get its a scanner site, but the correct operation of NAS is promoted here. This info is (on most systems) broadcasted openly on the control channel, so why not log it into the databases for those who want to properly (and have the correct skillset) to do NAS safely? Its a very trivial piece of info to snag off the air for those in the footprint of the system as well. For folks that are travelling, not so much.
Input frequencies are not hidden on conventional (along with PL/DPL which scanners also technically DONT need) so I would argue if its done for security of the trunked system, that is in conflict to how conventional info is handled.
