I havent read anything about them simulcasting....They probably wont touch the old UHF system until the new one is signed off on.
As for changing the Oat Mtn freqs.....they probably planned back then on what frequencies they could use....changing it all out now would most likely involve a lot of radio reprogramming. Plus I would think that area (West SFV) would most likely be covered by the new LA County System Sheriff/Fire system, as they have far more units operating in the W Valley than ICIS members.
I have heard San Fernando units using ICIS when they book people into Twin Towers downtown....or when they are at County USC etc. They called it Tac 4 or channel 4.
As for any new members...I would think the cities that are members of Verdugo Fire may switch their PDs over once they see how robust the system is.

If I understand it correctly:
470.3625 is the frequency for Red 16 Conventional. If a Verdugo unit is operating on Red 10, Red 11, Red 12 (conventional onscene frequencies) or on any other conventional frequency (LACFD Tac channels) and hits the Emergency Trigger, it comes up on Red 16.
Red 16 is also LAFD and LA County Fire's access channel into ICIS.
If they are operating on a TG in trunked mode and hit the Emergency Trigger, it comes up on Red 15 TG 33696
>>>Ok what is Red 16 Conventional? Verdugo has been testing ICIS Red 1 and Red 16 Conventional.

Plenty of testing with 72 and 73 this afternoon. Testing done on ICIS Red 1 and Emergency Channel Trigger, Red 16 or the old Conventional Red 5 freqency.
What is the difference between CentraCom and OrbiCom? Both were tested and heard on the same ICIS Red 1 TG. (Mobile vs Handheld?)

I have no idea, but I am getting more confused all the time. Red 16 hmmm. I read the post above but is it going to be ICIS Red 1-15 and Red 16 Conventional or will there be more conventional freqs. My hope is dispatch will be repeated on a conventional but I hope to win the lotto too LOL

The 5/6 tones are going away, if that is what you are asking.

Yes and No. Guess what I am asking is there going to be a conv freq that dispatch is repeated on. That way I could just leave it on monitor. Also when if ever will Mother Motorola come out with an alert pager/monitor for trunked system. I would like something more rugged that the 396 to carry around.

earlier. Looks like you have a better chance winning the lotto than receiving Verdugo non-trunked in the future...

If you have untrunker you can watch them paging different radios and activating the emergency triggers.

In answer to Chet's questions:
Two-tone paging will end on the day of the change over. 5/6 tone paging will be used as a backup conventional station alert use.
Verdugo will not be simulcasting any dispatches on conventional UHF frequencies.
Yes there will be a few conventional (narrow band) tactical channels for fireground.
To my knowledge Motorola does not have any type of Minitor pager like device for a trunk system. After the change over, BC's radios (portable and mobiles) will be paged over the trunk system. Two-tone paging is only useful (in the Verdugo systyem) when the BC is out of quarters. Front line personnel (except for members of Sierra Madre FD) do not carry two tone pagers for dispatches. Instead they relay on their portables when away from the station/rig.
If you want to have a small type II radio to be use like a Minitor (affliation with the system required), then you'll have to wait for Motorola to come out with a 450-512 version of the XTS4000. A very cool radio the size of a iDen phone. At this time the XTS4000 is only available to the Feds in VHF and UHF low (380-406 I think).
I hope this answers some of your questions,

Could be OpenSky and/or encrypted!
As far as the "CentraCom" and "Obacom", those are the types of consoles that are being used at Verdugo. They currently have both at each position.

From what im hearing the green ch's might stay... So since Sierra Madre is on VHF right now, what are they going to do with ICIS?
With enough questions, I might just get this ICIS system figured out. 
Will ALL traffic on the Red Channel TGs be broadcast throughout the entire ICIS network, or does a cell site just broadcast it if a unit is "associated" with that site?
For instance, I will only hear Glendale TGs on the Burbank Cell when a Glendale unit is closer to and hitting the Burbank Cell instead of Glendale's Cell site. Then I get ALL traffic on that TG through the Burbank Cell (I'm not sure how long the Burbank Cell continues to broadcast the Glendale TGs before ignoring the traffic). SO, if Montebello Fire is broadcasting on the Red 1 TG, will the entire System hear it, or does just Verdugo and those who have the Montebello Control Channels programmed? During tests I'm hearing ALL the traffic through the Burbank Cell. Will that change? Why isn't ALL traffic from the various TGs broadcast throughout the entire System and all cell sites all the time?
If Burbank PD is in pursuit heading East through the San Gabriel Valley, I'm assuming I'll hear them through the Burbank Cell Site as they "associate" and transmit through the various Cell sites as they proceed east. Do ALL the cell sites hear such traffic? What determines whether All Cell sites broadcast a particular TG or keep it just to the one Cell site and "associated" units?
I guess this ICIS System is really quite amazing when you think about it!

Any talkgroup can be broadcast through any combination of cells. The determining factor is having a unit affiliated to the cell. For instance, a Burbank TG may be broadcast in Burbank, Montebello, and the Antelope Valley if units are affiliated on those cells. If the unit in the AV moves to the Santa Clarita Valley, the TG will stop being broadcast in the AV, and start being broadcast in the SCV. We suspect Verdugo Red-1 will always be broadcast on the Burbank, Glendale, and Montebello cells, since there will always be units affiliated to each of those cells, but will appear on other cells only sporadically. I hope this helps.RobertW1 said:With enough questions, I might just get this ICIS system figured out.

Also, thank you for your gracious remarks; it's taken an immense amount of work by many people to get us to this point in the evolution of ICIS, and it's gratifying to hear appreciative comments by unbiased third-parties.
Verdugo Update
Monday, November 5th, Verdugo will commence operation on the ICIS regional trunking system. The initial announcement will be at 0700, with the actual cutover taking place at 1200 hours.
All units on all frequencies stand-by...
Drum roll please...
(I'll start breathing again Monday at 1205 hours.)
