P25 is not limited to Federal Agencies, so looking up the Federal NAC (Wiki) table won't help with a Part 90 License.
IS this ENC or CLR - listening might help ID the user. bldg Names, etc
Sadly not all FCC licenses update for each mode they use
Also, this could also be an image from another band.
Im getting 464.2125 P-25 Nac 201 . Cant seem to find anything on it other than Fed Protect.
Why on 464 Mhz?
