This has been a task of mine for a while, so I am very curious too. Please
include me in any answers found.

I have personally heard NPS comms on VHF repeaters 169.775, 170.05,
170.5125, 173.825, and 172.45 (all with NAC 4C5). I don't know their usage
or channel names.

Also, I believe Wolf Trap operates on UHF freqs. I have identified 408.975
and 410.5125 (with the same NAC 4C5).
