Once again, the LACoFD will not be operating on LA-RICS, for most operations. They have a new layout of analog, unencrypted UHF frequencies, many are ones that have been given up by the LASD when they moved to LA-RICS. The list is in the RR database, or I can post it here, if you want. Many of the freqs are active.
Re: LAPD/LAFD. My understanding is a new system is still a few years away and I've not read anything that indicates the LAFD will be a part of it, though I don't know for sure. Their PIOs are pretty open about things, so it might be good to see what they have to say. The LAFDs seem pretty happy with their 800 MHz frequencies, from what I have heard.
Scanning in SoCal is not dead, though the Cal Atty General's edict about PD encryption is making most LEO comms unavailable, sadly.
