I apologize if this has been talked about, but I couldn't find it.

I have heard from a really reliable source that METRO is ditching ALL of their standard frequencies that we have all grown to love and switching to the 700MHz system in three months (I assume to mean that as August 2006).

I also hear it's going to be encrypted, but I do believe he is simply confusing digital with encrypted.

Does anyone have any more detailed information? I have BC796D scanners, am I going to be able to listen anymore? (It's actually pretty important that I do. :p)

Try about 18 months from now. I cannot see how a new system could be constructed and in operation in 90 days. They have not even started on the new system. Perhaps the "Open Sky" system will work poorly like the one in PA. A waste of taxpayers money as I see it.

If the LVMPD was really concerned with being able to talk to other public safety entities in Clark County (NLVPD, CCFD, NLVFD, LVFD, HPD, HFD, and some others) they would have joined the SNACC 800 MHz system that seems to work well and is being expanded outside of the LV valley into parts of NW Arizona but I suspect that the LVMPD wants to have total control over their own system and is not really concerned about mutual aid and cost effectiveness. Another victim of high priced, fast talking M/A Com salespersons I think.

The LVMPD probably wants total control over their system and could care less about the ease of interoperability if they joined the SNACC system in Clark County. It would be cheaper to go with SNACC but they do not care when it comes to taxpayers dollars.
Those administrators that made the decision probably know very little about radio and are easily fooled by fast talking, high priced radio system salesmen.

in order for a digital trunked radio system to work properly the system would have to be P25 compliant

Where did you hear that? There are digital systems that work properly that are not P25.

I suspect that LVMPD's VHF high band system will be around for some time to come given how slow government often operates and the problems that have surfaced with other M/A Comm systems in different parts of the country.

New Frequencies

Sorry to bring up an old thread, *BUT* I was wondering the same thing myself. I had not heard about them putting in an OpenSky system, I was under the assumption that LVMPD was going to implement a regular old EDACS system in the next few years. I had read an article about the implementation of 700 MHZ for radio communications and had heard that it was being tested with an LTR Passport system down there...but I'm not sure that anything was finalized with the usage of the LTR system.

Back on subject...I looked in the cityfreq.com database for Las Vegas, and I found the following frequencies in the 700 MHZ band:

765.5125 Las Vegas Metropolitan Police
766.3125 Las Vgeas Metropolitan Police Department
794.0875 Las Vegas Metro Police

I also saw that they had some 803 MHZ and 821 MHZ frequencies registered, so the system they are planning to put in (whatever kind it is) is possibly going to be used on these frequencies. I can definately see the need for 700 MHZ frequencies in Vegas, with all of the casinos using the UHF, 800 and 900 bands for their systems, open frequencies are few and far between.

I suppose (and correct me if I'm wrong) that the current VHF frequencies that Metro are using are inadequate for use in hotels and casinos, or anywhere indoors for that matter, and that is why they are considering a higher frequency band, with better reception on the strip and in the suburbia of the surrounding metropolitan area.

I haven't had any experience with the OpenSky system, but from what I understand, it is much like a cell phone TDMA system. It sounds like it has (like many other MA/COM products) a high propensity for failure, and I'm not sure that would be good for Vegas, as it is one of those places where you can be in a life or death situation in the blink of an eye...

In case you were wondering, the following frequencies are registered to LVMPD other than their VHF ones (Courtesy of www.cityfreq.com):

765.5125 Las Vegas Metropolitan Police
766.3125 Las Vegas Metropolitan Police Department
794.0875 Las Vegas Metro Police
803.1875 Las Vegas Metropolitan Police Department
803.7875 Las Vegas Metropolitan Police Department
804.1875 Las Vegas Metro Police
805.1875 Las Vegas Metropolitan Police
814.2375 Las Vegas Metropolitan Police
814.7625 Las Vegas Metropolitan Police
821.0875 Las Vegas Metropolitan Police
821.1875 Las Vegas Metropolitan Police Department
821.4750 Las Vegas Metropolitan Police
821.4875 Las Vegas Metropolitan Police Department
821.6750 Las Vegas Metropolitan Police
821.9125 Las Vegas Metropolitan Police Department
821.9375 Las Vegas Metropolitan Police Deartment
822.3500 Las Vegas Metropolitan Police Dept
822.7000 Las Vegas Metropolitan Police
822.7875 Las Vegas Metropolitan Police
823.0125 Las Vegas Metropolitan Police
823.3750 Las Vegas Metropolitan Police Department
823.6250 Las Vegas Metropolitan Police Department
2459.0000 Las Vegas Metropolitan Police
2475.0000 Las Vegas Metropolitan Police
4940.0000 Las Vegas Metropolitan Police Department

Some of the higher frequencies have multiple users. I'm not quite sure even what some of these could be used for, but I'm sure someone knows, and could enlighten me. Thanks!
