Is it possible to query the database to discover P25 Trunked systems with 400 Mhz sites nationwide?

400 is a wide swath of band
406-420 Federal
430-450 Amateur and very few Trunk
450-470 Plenty out there
470-512 Plenty out there
No one will have a Nationwide set of frequencies tho.
If the data was submitted, yes it will be searchable
Altho a little more info from you on what you are looking for will be helpful as well as updating your profile
to show a location, which might provide more QTH specific responses from members
That URL returns a 404.
I could not find anything in RR that provided filtering options to search the database, such as a frequency limit and a protocol or some way to identify a P25 system. My location is irrelevant since I want to search nationwide. I wanted to find anything P25 400-520 Mhz nationwide.
Although a year out of out of date, I was able to find what I was looking for on Project25.org.
I was attempting to figure out which 2nd band to choose for a Unication G5. VHF or UHF. There are no P25 400 MHz close to me, but I did find that WV statewide uses 400 where I may travel to soon. One thing very interesting I discovered was the Wisconsin State system uses 139 and 140 MHz frequencies.

yea that Project25 page is just a data dump from RR (especially seeing the USNS ships under Boston)
Not being a paid subscriber, I do know there were previous search pages for Trunks maybe one of the other subscribers can point you in the right direction or also try the Wiki at
Category:United States Trunked Radio Systems - The RadioReference Wiki
OK, thanks. What project25.org has helped.
Is this not useful? - Digital Frequency Search

Nope, DFS is just like the FCC a data dump of licenses.
a. It won't confirm use
b. It won't have the SysID etc
c. It won't confirm the actual modes being used (DMR, P25, P25 Phase II, Cap+, Con etc)

I think the best for the OP is going thru the Wiki of each state and then pulling up the UHF trunks (for those that have a wiki page)
The database doesn't "discover" anything. What's listed in the database has been submitted & previously "discovered" by members
Did not mean for the database to discover. Meant discover what is in the database when I said query the database.
That would take more effort than necessary. The information is in a table on project25.org, although a year old it probably has not changed a lot. GTR8000 answered the question. There is no search feature of the RR database to filter by those criteria.
What is the purpose of querying just 400mhz p25 systems?
C'mon man, take the time to read the posts if you're going to participate in the thread...he made it very clear why he was asking.
