Default Help me identify federal frequencies in Sacramento

I had a great time last week in Sacramento. I brought my 396T, programmed for the local TRSes. I had a great time listening to the Sacramento City / County units as well as the local CHP frequencies. As part of my trip, I took the scanner out of scan and searched around some other places, specifically, the federal UHF/VHF bands.

I was hoping someone with local access or expertise may help me identify these frequencies.

166.925/P25
167.7875/P25
169.8375/103.5Hz - I think this is USPS delivery / loading operations
407.1375/P25
414.325/P25 - Encrypted. Never heard anything in the clear.
417.2/127.3Hz - Federal Protective Services

407.1375 w/o a NAC it's assumed to be USPS and likely $482

If it is it's simplex. FBI Sac hasn't made the P25 changeover yet. And neither has the Bay Area, which is where this freq is also used as an analog repeater.

I used to hear this FBI repeater some 150 miles away, when I had a huge VHF antenna on a tower. They were simulcasting it on a half dozen frequencies at the time. A similiar system was in use by the San Francisco FBI office too.

The San Francisco FBI is using 167.6125 as their primary channel these days. Sometimes the encryption breaks down in outlying areas and they are forced to speak English instead of static...

FBI in the Bay Area has several "Nets" that use a common input with different outputs. Nets like West, North, East, etc. The thing about the Bay Area is all the sites (including a ton of voting receivers) are linked back to the dispatch center in SF, versus the Valley where there are many stand-alone repeaters. I've yet to see any P25 capable repeaters in the Bay Area but Sac has some. There's one stand-alone in the Valley operating primarily in P25 mode.

I have typed list of those San Francisco FBI repeaters that used to multi-cast. All of the repeater outputs were on 167 mhz, while the inputs were on 164-165mhz and 172 mhz. There were several tac freqs down on 163 mhz too.
