question about Lauderdale County

[nexus]

I need to know if either the sheriff department or the lauderdale police department use an MDC signal at the end of transmission? This would include dispatch as well.

The reason why I ask is because a new talkgroup has appeared recently on Harrison County's TRS, its AFS 06-107 and it is clearly a "PATCH" to another frequency. I've heard 2 or 3 different agencies at various signal strenght for over a week now. The strongest and clearest signal seems to be identifying themselves as "Lauderdale" and units with a 100 series number like 123.

The thing is when they unkey, there is a quick MDC squwak at the end of each transmission. So I'm trying to identify if they are Lauderdale County or PD in MS. And then that will tell me what frequency the county dir of comm patched. I looked at both SO and PD freqs on the database and the odd thing is NOTHING around here uses those freqs so I'd be puzzled as to why it's being patched onto the TRS.

At first I thought maybe STATE PD (155.490) or COAST PD (155.730) was patched or even the national PD (155.160) but now I don't think so.

I know someone on here is living in Meridian and should be able to tell me if the agencies there have the MDC or not.

Nexus,
i know saveourtrainsmichigan is in Meridian / Lauderdale County. he's the one that made the forum post regarding his fire/ems stream for his area.
also, does that TG seem to sound really bad to you at times or is it just me?

Nexus,
It very well may be Meridian/Lauderdale Co....

I know that Meridian PD has the "sqwauk" at the end. Cannot recall if the SO has it.
Meridian calls their dispatch "Central" and they also use Phonetic alphabet callsigns (A-Alpha, I-India,...) which precede a two digit number

Referenced in some traffic was "... stop on 19. ...", and there is a Hwy 19 which goes through the county.

Supposing this is who it is, the question is.... why would Lauderdale County be "patched" onto the Harrison 800 TRS??

Does not seem to be any inter-op communications happening, just more of an audio stream.

Maybe the system manager is having a little scanner-ish fun??? LOL

Odd, yet an interesting mystery to solve

Note if you hear interstates 59, 20 or Highway 45, those run through the county and can be a good clue of some sort.

Will update if I come up with any more stuff

I seriously doubt they're interop'ing with them. My guess is someone has configured the talkgroup to a high-band frequency that has CSQ. So basically it'll rebroadcast any transmission it hears.

It just happens the only identifying info I've heard so far stated "Lauderdale" as a callsign. Also tonight I heard a unit run a plate with a MS format.. Three numbers and then three letters with the first letter being L. So the qestion is, WHY does harrison county have a patch to 155.7900 mHz (seeing how that is Lauderdale SO's dispatch freq)

And I don't think it's the talkgroup that sounds bad, I think its just a distant station just outside of it's range. I know I've heard 2 or 3 different agencies on it but the one with the MDC squawk at the end of each trans identifying themselves as lauderdale are the strongest.

Could just be a patch test possibly precurser to setting up a patch for Statewide High band 155.4900????

 

[bassmkenk2508]

I think a patch for the statewide freq is a great idea for inter-op purposes and would prove smart for this hurricane season! I agree with what milf said, it may a testing phase.

Update:
Just heard traffic on 06-107 regarding the intersection of 39th Ave and 8th St. In MS that intersection occurs in Gulfport. But the quality on the transmission was weak.... Odd if this was a local agency



(unless some of it is local traffic being patched from a distant repeater or something like that which could cause a weak "reception")

oh well, i'll have to search for more informative clues...

 

[bassmkenk2508]

well, i think i can say that we have been hearing Lauderdale S.O. on 06-107.
Just heard traffic about stuff happening on streets Pineridge Dr., Oak St., and State Blvd., which are all connected sequentially just outside of Meridian. Then a vehicle was pulled over on Pineridge Dr.

 

[nexus]

So that would mean the Patch is going to 155.7900 mhz.

To my knowledge there is no agency here on the coast that uses that frequency. I wonder if it was a mistake. Because 155.7300 is the coast Law Enforcement net freq. Waveland PD *use* to be on 158.7900 but I don't even think their department exsists anymore. I only hear BSL and hancock county SO on that loaned TRS.

I figured it might be some kind of test thing going on, but the question of WHY that frequency is baffiling. It's kinda cool to be able to hear Lauderdale SO from all the way down here though. heh.

Thanks for the extra help monitoring Bryan... I take it you're back in OS for the time being?

Do you think it would be wise to send Gil Bailey, the Harrison County E911 director (person in charge of the TRS) an email asking him the purpose of that talkgroup? heh

Oy Vay...

Your welcome. Yep, summer break from MSU. It is interesting to catch on to the developments in the systems down here, such as this one and the conversion to digital TGs in Jackson County.

Speaking of Jackson County, I caught an analog TG OSPD was using for a couple of nights (unsure of dates) for some dispatching. I will make a separate post regarding this though.

I saw that.. Don't forget to update the DB with that information. I'll have to add that to my list. It must of been made AFTER I got my list.

Yesterday morning I tuned my FT8900 into 155.7900 and there is a transmission that is occuring every few seconds, real briefly. I can't hear any audio, its just something breaking the squelch, mechanical almost, and it happens at the same timeframe each time. I noticed that some of the time the TRS will pick it up too. Also as it was picking up someone's transmission from lauderdale I noticed it breaking the squelch on my 8900r. Freaked me out, 1/4 wave antenna on I-10 and a transmission from Meridian was breaking my squelch. Must of been conditions.

The Duct Path in MS is amazing this time of year and in the winter... Path is as follows: Southwest MS from Southeast MS and LA, and direct line from Northeast MS to Southeast MS/LA... Some drift into the AL area occurs on this path, and slight drift from Central LA on the other path.... Rarely youll also get a Duct from GA.....

 

[bassmkenk2508]

heard last night the call "Jeff Davis" on 06-107, no MDC in transmission.

Here comes the interesting part...

MS has a county of Jefferson Davis.
And interestingly, the SO's main frequency for Jefferson Davis Co SO AND Lauderdale County SO are both 155.79

Hmmm.

I just thought, that maybe Harrison County is testing the reception of 155.79 to get a feel for reception of 155.73 and/or 155.49, in prepartation for a patch in. But maybe they want to be able to tell who is coming through to reference to the distance the tranmission was sent from.

Just my immediate thoughts.

 

[nexus]

thats good info.. thanks for sharing. I've been hearing other agencies in there at the same time but could never really make out who they were. Lauderdale seems to be the strongest.

 

[INDY72]

Jeff Davis SO is usually stronger in signal this time of year... but fades in high summer till early fall...

 

[nexus]

conditions are funny... heh

this evening on the way to work (2300 hrs) I was listening on the talkgroup and Jefferson Davis County was coming in like they were only down the street into the patch. Very clean signal.
