Good work, creators4. I can also confirm your two VA catches are consistent with what I have observed. There is a lot on the 162-174 MHz federal band that has yet to be mapped by this hobby community, so I'm glad to see that you've done some work on this.
It frustrates me when other hobbyists sometimes say, "If all the traffic on a frequency is encrypted, the fact that it is in use is irrelevant". There is a lot of useful sigint information that can be gleaned, even if an audible voice cannot be demodulated, or an intelligible stream of data characters decoded. For one, I'd like to see someone closer to the VA scan and find another frequency using NAC 3F8. That would tell us the presently unknown VA Police input. (The input for that analog channel used by maintenance is 166.7125 BTW).
Having Ensign Peak blocking the path from my location to SLC has been a bit of a hindrance, especially in associating inputs with their output frequency. The fact that so many of these operations use the default NAC 293 also complicates matters. There's undoubtedly a lot I haven't caught yet, but here's my P-25 and analog 162-174 MHz lists:
