Yet im still not sure about this digital thing im having i looked in my manuel and it says put it on FM and it will recieve the digital on its own but it dont show any of the talkgroups so i have all the new system frequencies on motorola and the CC's locked out unless all these are analog and no digital. ((((((((this new system is so weird )))))))

If you have the Pro-96, just program the system normally. The -96 will figure out when a transmission is digital, and will decode it normally.

You'll notice right away the difference in the sound. The "MO" in the upper right corner will change to "DG". That means digital. As for conventional digital, I dunno what pops up on the screen, but if you're curious about monitoring a digital system right now, load up the Davis trunked system and drive over there. You'll hear digital traffic by the PD.

By your posts, you're becoming confused, and overcomplicating it. Just load the trunked system the way you loaded the old one, and the -96 will do the rest of the work.

Swat - I believe all those talk groups you listed are being broadcast as analog. I've heard all of them, (and others), on my analog-only BC245. The one "weird" thing I've noticed, and it's been discussed a little here, is that you'll hear some talk groups on both sites. So for example, you'll sometimes see/hear Sac PD Ch1, (id 60304), on Site 002, (what we referred to as the county site for a while). You'll also see/hear City Fire talk groups, (59248 and 59280) on Site 001, (what we referred to as the city site). As you know, in the past, Sac PD was only on the City TRS and all fire was on County TRS. For now, it seems that sometimes you can find them on either site on the new hybrid system, but not all the time. I wouldn't be surprised if a lot of it has to do with radio testing. There's plenty of time for things to change.

Just as a side note, for the last day or so there seems to be a lot of fire equipment going out of service for a couple hours at a time due to "radio reprogramming".

The only digital transmissions I have heard on the system to date were on the Radio Service Talk Groups

45040 and 45072

Let's hope they keep it that way, those digital scanners are expensive!

Edit: More analog talkgroups:
56528 - site 002 - Mercy San Juan
56656 - site 002 - UCD

Ok.. yes bill i am very confused and i have got my head into the books about digital/analog systems so i can put that aside... and i do have DAVIS system in and going the weird thing is you say just put the NEW system frequencies in and the pro 96 does the rest... well it dont for some reason i have left them all on FM. yet when i put them all as MO they work well and on the other hand. DAVIS shows DG where the MO goes. and yes the book also says just put in the digital frequencies and let the pro 96 do the rest ((((page 97)))) and thanks guys for your help and time for my confused thoughts

Today 4/27/06 I monitored Station 117 equipment going to stn 111 for radio upgrades.

So far, from what I have heard, the reprogramming is going well. The hospitals should be finished by at least next week.

What does everyone think, or perhaps know, about what's currently going on with the transition? I ask because it seems as though we're still quite a ways away from any digital talk groups. (As antfreq mentioned, he's only heard digital on two radio service id's). Plus, all of the new talk groups that are showing up on the hybrid system are broadcasting in analog. There's only a fraction of the existing talkgroups from the city and county systems currently on the new system, and it would take much further testing if they were to go digital.

I guess what I'm asking is, do you think they are going to migrate all talkgroups from the "old" systems to the "new" system first, and then at a later date work on the digital implementation, and then later still, rebanding?

I hope this makes sense, it did in my head!

The following is what I understand to be accurate.

1. All radios are digital, 700/800mhz, and rebanding ready.

2. Once all of the programing and equipment switch-out has been completed AND the switch has been made to the new system, SOME digital and encrypted talk groups will be implemented

3. Many, many months, maybe a year, two years, or more, the switch to all digital will be made. Remember folks, we're using government clocks and calendars here.

4. The switch to the new system ( programming and equipment switch-out ) should be finished by the end of July.

5. Eventually the system will be FULL DIGITAL. I don't see this as a technical problem. Simple making sure everyone is on the same page before going to the next steps.

I've heard digital talk group testing from field technicians all over the county and it sounds GREAT.

6. My opinion now. From face value it's kinda scary. Everything seems to be going quite smooth from the end user percpective. That in itself is unusual. Fingers crossed.

Thanks antfreq, as usual you provide unique insight.

The thing that bothers me is hearing some talk groups on both sites. Maybe this is just because they are in the testing phase, but I wonder how you would go about listening to a single talk group if it seems to bounce around between the two sites.

For example, what would I do if I only wanted to listen to Grant School District PD and nothing else? We know the talkgroup ID, but which site would you program it into, or which site to monitor? They are bouncing around between both sites constantly right now. In a way, it's almost like trying to follow a trunked conversation without a trunk tracker. One minute you'll hear them on site 001, and the next on site 002.

That is pretty much what I have heard, too. I have seen some of the new radios from our cache, but did not note the model (it is smaller, though).

Gotta love #3 - ...we're using government clocks and calendars here - That is sooooo true. I lost count how many times I heard the start date for the programming.

CH 40? sac metro fire

Does anyone know what ch 40 is and what site...

Tonight a heard a commercial alarm response and the units were told to to respond on ch 40.
Also who has alpha pagers everone in the dept.....Are they on Vhf like a volunteer...

What Talk Group?
What was the address they responded to?

I've never head such a thing from Sac Regional Fire Dispatch.

I have never heard of a Channel 40 before on our Fire Dispatch System. I know when there is a major incident and a need for Tactical Channel, dispatch will voice the "Tac Channel" that at the end.

Example:

"Operations on A6, A - Alpha 6"

The Tac channels run from A6 to A10 for county operations and B6 to B10 on city operations.

As for pagers, I have not looked at how that is completely structured. I would say for anyone that is "On Call" and would need to respond to or be made aware of a major incident at any moments notice - MCI's, Level II - III HazMats, Large Structure Fires and so forth.

Hope this helps a bit.

Falcon 30

FYI:

Falcon 30 - Placer County Sheriff's Helo announced around 1800 hours on Sac PD's Channel 1 Dispatch that they are 10-8 (In Service) to assist.

Talk about some major air coverage in case things really go sideways.

I would say the great weather would be a factor in the increase of criminal activity tonight, throughout the weekend and beyond.

I know the gang bangers and the other low lives have been having a field day in their field lately; an increase of shootings, robberies, car-jackings and any other crimes against the public and property is really apparent.

They definatly said respond on ch 40 and all tac ch's wee quiet.

Hmm...

A mystery.

Do not know what to say.

Do you recall at what time and the location of the call was?

I could some research on Monday and see if there is any indication of this "New" Tac Channel.

As I write, Falcon 30 is assisting SSD District 4 - Zone 1 units for suspect/s on Wright Street at an apartment complex. Vehicle VIN matches who they are looking for.

I can here there orbit now.
