Looks like this talkgroup on the ICIS systems is patched to LA-RICS Talkgroup 318 Aero Bureau Dispatch. Correct me if I am wrong. I was listening to both at the same time.

Which site were you listening to? For ICI?

 

[tsalmrsystemtech]

Its either the Glendale or Montebello Site.

I looked tonight when the talkgroup opened up and its only receivng ICI Regional Interop 1 on the Montebello site for now.

Hey just jumping on this bandwagon as I was looking at scanning LACOFD next month while I'm in LA. I see that there are 400Mhz future use channels listed in the DB with a time line of the second half 2023. Has this change occured yet? Thanks!

Not yet.. The old ones still are in use. There has been intermittent testing on some of the new UHF frequencies, but they have not changed their band plan yet.

LASD Disp 13 - Norwalk / Pico Rivera (483.7625) currently has an automated voice repeating a bunch of phrases, does anyone know if they've switched over to LARICS?

I'm not hearing that on Dispatch 13

 

[patin]

I'm hearing NORMAL Dispatch on 13

Yup It sounds normal now, maybe they were doing some temporary testing or something. it happened around noon (12-1pm)

Typically when you hear the Harvard sentences being read, the Motorola field engineers are conducting coverage testing, BER testing, and simulcast sync testing. It may become a conventional resource for LA RICS use once LASD is fully cutover to the trunked system.

Same testing that we are seeing on the conventional overlays and mutual aid channels at this time.

That's just a patch of Blue 8, 470.5375.

Hopefully in California, Senate Bill SB719 will be passed and taken into effect on January 2024 where law enforcement are required to either unencrypt non-tactical radio communications, stream communications online or also but unlikely allow purchase of equipment to scan encrypted communications. Law enforcement agencies are arguing that removing encryption will have “significant burden to agencies that went to tremendous expense to obtain new technology or have previously encrypted their communications.” We all know it’s BS because many if not all agencies that did encrypt their systems was all done by a click of a button in adding keys to their digital frequencies and it do not have any cost in replacing any equipmen if they decrypt.

@garretk: I'm not going to derail this thread into yet another encryption debate, so I'll just refer you to lots of other threads on the subject here and elsewhere for why your argument shows a misunderstanding of the actual work involved.

I would love to learn how to add 8 AES-256 and 12 DES encryption keys to 36 radios with "a click of a button", without the benefit of OTAR - which even then requires interaction on the subscriber side.

Edit: After considering this, could you provide us all a link, or a PDF of Documentation from Motorola, Kenwood, Harris, et. al, that provides instructions on how to click a button to accomplish this?

I think this bill was already shot down months ago or even a year ago. This is old news.

I happen to have Motorola's CPS program with Advanced Keys Administrators. Programming keys is very easy to do for an experienced programmer as Motorola themselves create the actual AES-256 key and they just mail it to the agency's programmer. The programmer reads the key and assigns the key to specific channels, talk groups, and radios. Then from there, it's just cloning the program into the radios. Whether or not they use OTAR it's up to the agency as I believe is a feature that needs to be purchased from Motorola. However, they have key loaders that can easily program the radios whether they use the KVL 5000 key loader or they have a programming wire that they plug into their laptop. Yes, it just takes labor to manually program each radio but as you said 36 radios and it's as easy as writing the program into the radios after they have it all preprogrammed and ready to clone. Shouldnt take more than a day if they have all 36 radios in front of the programmer. Obviously, it's not just a single button click but if they have OTAR I'm sure it's actually one button. Here is a pdf of part of the Advanced Key Administrator software tutorial and there is a screenshot of the CPS that I use to program Motorola XTS and APX radios. It's not the entire programming instructions because there is a lot to learn. I'm not going to provide the entire instructions but just want to give you a taste make you happy since you think I have no idea what I'm talking about.
