My question if they do bring it back, and its on a TG what good does it do us. AFAIK (and of course thats not much) unless you have a /\/\ on ICIS you can't decode the 2 tones.

Now I hope they bring it back on a conv freq. Then I see a Minitor in my future.

It was a two tone, not just some random beep. I also think it was quit a coincidence that it was played right before a BC page.

What freq are you hearing the tones on? If its a TG we can't decode it that I know of. If its a conv freq we can. I was told that something is up but really not sure what. It was made to sound like the departments want the paging back. We shall see.......

NEWBIE ALERT...

Can someone take a moment and explain the two tones thing ?
Is it the the two longish loud tones (800hz ? attention getters) heard before a dispather message or are you talking about something else ?

What does Chet mean /\/\ and decoding tones ?

If two tones means the attention signal ? I heard those twice on Red 1 dispatch
and on Red 3 last about 6:15PM yesterday.

I think I can answer that since I'm the guy that built the tone
generators that are used for the various tones used by Verdugo. And
last week, I was requested to make a couple changes to those tones -
including the "2 tone" before a full assignment. It was done at the
request of the firefighters who can more easily tell if it's a full
assignment dispatch (as opposed to a single unit call) before hearing
all the apparatus listed in the dispatch.

Steve, /\/\ is just a fancy way of saying Motorola.

Decoding the tones is when tones are sent out and it opens the radio up to rx. Unless the tones are decoded the radio remains silent. That way you only have to hear what matters to you, not what all the other departments are doing.

The two tones in this case seem to be used for a different purpose.

Bob Hope and ICIS

Not exactly new information....but more information on Bob Hope Airport's use of ICIS:

WIRELESS COMMUNICATIONS USE AND MAINTENANCE AGREEMENT
BETWEEN THE CITY OF BURBANK AND THE BURBANK-GLENDALEPASADENA
AIRPORT AUTHORITY – A staff report is included in the agenda
packet. In early 2006 the Authority authorized Staff to improve the Authority's
public safety communication system from an analog system to a digital system and
to allow public safety personnel to participate in the Interagency Communication
Interoperability System ("ICIS"). As part of this upgrade, the proposed Wireless
Communications Use and Maintenance Agreement (copy included with the staff
report) between the City of Burbank ("City") and the Authority would provide ICIS
connectivity and roaming capability for 64 Authority-owned digital radios
primarily used by the Bob Hope Airport Police and Fire Departments. Also
included as part of this cost is radio maintenance service to be performed by the
City of Burbank.

Additional terms of the proposed agreement are:
• Term: Ten years.
• Termination: As early as 90 days and requires mutual
agreement.
• Initial Fee: $25 per radio per month, including basic
maintenance and ICIS fee of $5 per radio per month for
roaming privileges. This fee includes any fees that the City
pays to ICIS. As the representative ICIS member, the
Burbank Water and Power Department will pay the roaming
-2-​
\COMMISSION NEWSLETTER\10-8-07.WPD​
fee to ICIS directly and will act as the intermediary between
the ICIS and the Authority.
• Fee Adjustments: Every two years, based on increases in the​
local Consumer Price Index.

Looking at my logs...the most used radio for Airport Fire is naturally Dispatch....followed by Rescue 17, which responds to all the EMT calls with a backup from a Burbank RA and Engine. I havent heard the Crash engines since their training sessions.

The tones (700 Hz & 800 Hz) are just intended to alert station personnel to a full assignment.

What you do since Red 1 is simulcasted over Green 7 you figure out the tones and thier Hz's, of course posting here ;), and then set if available your Radio or Scanner on fire tones out with the freq as Green 7.

OK, maybe I have gone mad but a question for the ICIS gurus.

Do say Burbank Fire, Burbank Police, BWP etc use a different NAC? If so could someone take a /\/\otorola Astro and just program the freqs of the system (not the control) with the NAC of the department they are interested in and let it scan. It would let you follow a trunk system without being on the trunk system just like a scanner but with the hearing of a
Motorola.

With me I am just interested in Verdugo, mostly Burbank Fire. Is that possible???
