Does anyone have a complete list of the frequency line up (freq, channel, use)?
It sounds like 453.9250 MHz is 1 - Dispatch.
453.925 is definitely "dispatch", at least so far, but I haven't heard it referred to as F1 or Ch-1. Nor have I heard any police traffic at all on any of their other UHF frequencies, nor anybody mention switching to any other channel.

A check with the ULS comes up with:
WQCL798
453.0500 (R)
453.7000 (R)
453.7500 (R)
453.9250 (R)
453.0500 (R) is still Street Maintenance, as before
453.5250 (R) - Beverly Hills comes in very strong, so I doubt they'll want to use this for critical kinds of communications
453.7000 (R) is still Dial-A-Ride
453.7500 (R) not heard
453.9250 (R) Police
WQDH479
470.3125 (R)
471.1125 (R)
471.1375 (R)
All quiet these two days, as have been...
Those three freqs plus base and fixed control stations (16 or fewer of each) on
482.2125
482.4125
482.6125 are also on WQDH478, and it's been less than a month (6/22/06) since the City notified the FCC that construction of those sites has been completed.
Correction, 7/21/06:It looks like they have
not yet made the completion notification for the "larger" WQDH479 license. So maybe it's not quite ready yet, and with bunches of base and repeater stations, and 650 mobiles, that one is pretty obviously the "primary" license. Unless things change again.
KNFB476
453.3500 (R) nothing
453.7000 (R) D-A-R
453.9250 (R) Police
WPTL512
453.7500 (R) nothing noted
WPTW444
453.5000 (R) nothing noted

There are others, but they are either registered as Industrial (IG) or not enough radios to be PD (less than 15).
Also, what you hear that you might think is encrypted might just be P25, but in simplex too far away or too weak of a signal for your scanner to decode the P25 digital signal...maybe...hopefully.
That's true. The handful of encrypted messages I heard Wednesday morning were definitely encrypted, however - they were very strong, obviously came through the 453.925 repeater, and as I think I mentioned, twice the dispatcher ack'd them with very emphatic "Read you
10-2" or "Copy you
10-2." One of the units was a "F" unit, I don't remember who the others were. I'm way too familiar with weak and garbled digital signals after listening to them for five years, but these weren't them.
I'm wondering if, and this is another longshot, 453.925 is just a temporary dispatch freq until they get the T-band frequencies completely up and running. This is all pure conjecture (until we hear from somebody who knows something), but it seems possible that SVPD needed or wanted to get onto UHF as soon as possible, but with the late-June construction completion on one license, and none yet on the other, maybe the 470s and 480s just aren't quite ready. I wouldn't bet anything on anything just yet though, especially any of my own half-baked ideas.
