I already think theDOD System P25 380 mhz in the databse is to large.

Especially, when a new DOD site 605 is now online in the Sicily area of Italy. Now it is currently a separate site, until the database can be modified to add more than one country to a trunking system. I am sure that other DOD installations around the world will be joining this system in the near future.

Nah Gulf WIN came about due to an immediate necessity due to the oil spill. Though eventually something else would have surely brought it about if not for that. All Gulf WIN is, in very over-simplified terms, are up to 16 talkgroups on the various systems, that only certain radios programmed for all those systems has/had access to. They are all still there own seperate systems. Though now what started out in Orange Beach is on it's way to eventually becoming the statewide system for Alabama. The connections created to form the Gulf WIN will almost certainly be there waiting to be pressed into service for whatever other disaster may come along though I'm sure.

Couldn't agree more about the Navy 380 TRS too. But that's another topic for a place other than here.

EDIT: The Navy ELMR system actually began in Europe many moons ago. But again we digress from the topic at hand.

I had found that one too in my searching and then came across the Baldwin County stuff I posted earlier that contained many finer details I kinda forgot/lost that one. Thanks for getting it into the thread.

I tosed the whole set out there a while back, but no matter, the more the merrier. :)

Did you happen to notice if 505's status was Failed? Last time I checked 202, which 505 also shows up as a neighbor to, it was showing Failed there. Been a week or two since I last checked though. Always wondered why that little tidbit of info isn't stored in the logs too.
Also as I've mentioned previously you can't trust the neighbor site frequencies being correct either. No idea exactly why, but the sites are using different trunking tables, that aren't fully filled in either, so I assume Pro96Com is making erroneous calculations based on that. I guess the best way to explain it is to just look at my log files which I've attached here again.

Also just noticed all Sys 00A sites have the RFSS set to 1. The RFSS also increments with the site number. Though that may change once things get closer to being finished.

Yes, 505 showed fail.

Ok, not sure what's up with that but it's been that way a few weeks now. Also recheck my above post I've added a bit more relevant info since you replied. Depending on conditions I'll try to sniff around and see if I can freshen up my logs over the next few days.

Thanks for the additional Info. I'll keep searching the 700's and see what changes. Keep me updated.

No problemo. The Mobile County stuff seems very much still in it's infancy. Seems maybe there is something about Harris P25IP that doesn't quite set right with Pro96Com to. Did you see the max 68% decode limit I've mentioned too? It will occasionally jump to 70, but when on a Moto P25 at 100% it will also jump a few points above 100 occasionally too.

I talked to a local EMA Director last week about this system and he siad the State is already out of money and not to see it expand more than where it is now. We will see. He is not planning on his county getting on it. Orange Beach Fire and Gulf Shores Fire still use the VHF and 700 mhz. The same audio comes across both VHF AND UHF at the same time.

WOW, All the money that's out there for the taking to build systems and buy radios and they don't have the money? Though a great deal of compatible systems are already scattered across the state, or are in the process of being built out. Mostly all they should need are hard lines and/or MW paths and a few bits of hardware to tie it all together. Maybe funds for that type of thing are not as easy to come by?

On another VHF/UHF note, as shown in the Baldwin County documents I spoke of earlier there is to be 3 Yagi's installed on the Seminole tower to create a path to Escambia County, FL for Interop purposes, so that is something else to listen for.

Baldwin County Sheriff's Office

Heard today that beginning tomorrow, the Baldwin County Sheriff's Office will terminate their current patch between the 700 MHz and their old VHF system and that it will be encrypted.

I was able to hear Medstar tonight. They are on the UHF 400 mhz and 700 mhz. I don't have a talkgroup id for them. Sometimes I get a real strong signal on some of the controls other times I can't. I have figured out if you can't get a control signal just program all of the voice frequencies in as p25 and you will hear what is on the system.

Here is what I have been able to get
770.1062 Bay Minette
Id:05
46Bh-002
WACN: BEEOO
NAC 465

Seminole Site Id 04 with NAC 464.

This is the only trunked system that I know of that has different NAC's.

As far as Baldwin County Sheriff they must be on Phase II beause I don't hear them at all.

FYI. Picking up Baldwin County Sheriff's Office on 154.95 with a PL of 192.8. This is the input frequency for the old VHF Mutual Aid channel.

Just got back from the Huntsville Ham Fest. The 700 mhz system in Huntsville was full scale on my small whip in the motel room close to the Van Braun Center. There already is a a 700 mhz System set up in Montgomery according to my source. He said one will also be in Clanton He said the public safety are trying to decided how many talkgroups they get before they let other state agencies in. He did tell me that most of the talkgroups when it all gets said and done will be encrypted :-( As well as Phase II While out one night I did see 4 State Troopers up in Huntsville eating at Captin D's and I got the nerve up and asked them if they was aware of the new 700 mhz Digital Radios. And if they were going to them anytime soon ? Nedless to say they did not have a clue what I was talking about. It just proved to me how little is known about this new system. It is a long way from being finished from what I found out in Huntsville. Has any one tryed a GRE Scanner that is Phase II P25 and see what you can hear on this system ?
