800 MSP Patch running

[lebrunmn]

If you haven't been able to catch MSP on 800 MHz, here's your chance, it's been up for awhile, and it's loud and clear. Both sides of the transmissions are coming through--talkgroup 6544 on AACo System. If you monitor the patch and the 39 MHz channel, there seems to be no latency whatsoever.

Yup - must be some big joint operation tonight!

I noticed on 4/2 there were quite a few search warrants here in Berkeley Co. WV. I think it might be some kinda of nation wide or regional operation. I posted a news article a little bit ago about a stand off with FBI in Washington Co. MD.

Right now there is a post in the VA forum about a hostage situation in Fairfax VA. They aren't sure if it is real or a training exercise.

Also, on 3/31 I caught a lot of Customs traffic on NET1/6 of "Omaha1" doing surveillance on someone outside DC off I95.

Customs/DHS has been really active in the entire metro area this year. They have a bunch of helicopters at IAD. OMAHA-1 isn't always the same helo. N4068W is the one they were using on 3/31. They ended up in Baltimore before losing the target.

N5204J and N4043L are some others in the area.

This is the first time I have ever heard them on the system before. Yesterday MSP was asking for assitance for people jumping off a bridge. This morning they have been running checks on cars.

Here's another thought this. Now that the weather is improving, weekend beach bound traffic is growing and enforcement, accidents, etc will be increasing. Along the southern end of I-97 and along Rt. 50 coverage by 39.040 has to be poor, so it seems to make sense to use the patch.

Once we start hearing the MSP motorcyle units ( Motor 1, etc.) we will know that beach traffic season is here.

Don't know this for sure, so maybe someone a little closer to the action in AA Co can enlighten us more, but . . . it's my understanding that MSP purchased 800 MHz portables to use on the county TRS a while back. However, there have been some issues that prevented the full benefit from being realized - mainly, AA Co would not allow a two-way patch between MSP's low band freq and the MSP talkgroup on the TRS. Hopefully that has finally been worked out, which might explain why you're hearing all the activity now.

Hearing a hum on the 39.04 channel, sounds like a ground loop.

 

[troymail]

So I heard one of the units come up Friday morning going 10-41 (on duty?) "on 800".... seems to be unique radio IDs popping up on the talkgroup so perhaps they've moved beyond the patch need and are up to stay this time.

I've also noticed for quite a while that some MSP helicopters no longer require patching into the AA County system for MevEvacs and also come up with their own radio IDs.

On 3/31 while at the commissioners office in Glen Burnie I spoke with a trooper who told me that on 4/1 they were going to start using the 800mhz radios. Ever since then I have been hearing constant traffic on the talkgroup.

 

[pasadenamd]

I also have noticed that AA County Sheriffs having been helping AACPD on priority 1 responses if they are in the area. I also have heard recently AACPD priority 1 tones are put onto the sheriffs talkgroups. I have noticed this recently before the new MSP. I have noticed MSP on the AACounty system since Friday. MSP seems busier at night then in the morning. I like the quality of the new MSP system because it was hard to understand them when they were on the 39.----- system.

 

[trimmerj]

Has anyone determined whether the 800mhz radios are being retransmitted on the 39.04 frequency ?

 

[kb3jkc]

I don't live near enough to hear, but I would be extremely surprised if there is not a permanent patch between the MSP lowband freq and the AA Co TRS. Such a patch is used, to my knowledge, in every county in the state where MSP is using a talkgroup on a county TRS. This is necessary because MSP has statewide jurisdiction and presence, and there are often troopers working in or passing through a county where they are not permanently assigned. Only the troopers assigned to a particular county are issued radios for that county's TRS.

Without a patch to lowband, those other troopers would be in the dark to the comms of the troopers using the TRS. Some of the portables may also have talkgroups for barracks in adjacent counties that use a compatible trunked system, but all MSP cars across the state have the same basic lowband channel plan. That way, if troopers from Cumberland are sent to the eastern shore to assist with a major incident, say a big hurricane hits, they can switch channels and talk directly to the Berlin Barrack and its personnel.

I can confirm with little uncertainty that there is a patch to low band - I just turned on 39.04 and can hear the cars just as clearly as dispatch... they are both equally as scratchy but very clear.

EDIT: I've also heard dispatch talking to some cars that do not appear to be on the trunked system (I can't hear the car side although most patrol cars are very clearly on the trunked system)

Looks like the patch is down again - I haven't heard it during the drive times yesterday or today - or perhaps they're running it off hours to get a handle on the additional system load? 73 Mike

There was a MSP police chase about 20 minutes ago and I heard the whole thing from the patch. The chase went from AA to Baltimore City to AA and I heard all the transmissions. When I go to school between 7-7:30 i hardly hear the patch so that might be when you were driving? The patch becomes more active throughout the day.

 

[ka3jjz]

Yeah, they may just turn on the patch after a certain time in the morning, or perhaps the dispatcher forgot to activate it earlier this morning. I was on the road by about 7 or so - just around the time you mentioned 73 Mike

Over the next week, I am going to try to listen and figure out the times when i start hearing it in the morning. Also since it started i have listen to it from about 7-7:27 Am and never heard MSP.

Kinda funny that you mention Berlin Barrack in this post... I can say with 100% certainty that MSP Berlin does not patch 39.600 or any other lowband into the Worcester EDACS system. They carry M/ACom 7100 portables and use a cheap EDACS mobile (not sure of the model number). When other Troopers come into the area for special events such as Hot Rods or Bike week they are issued Worcester EDACS portables... Just a side note...

Question re: Customs traffic noted on or about 3/31/2009

I noticed on 4/2 there were quite a few search warrants here in Berkeley Co. WV. I think it might be some kinda of nation wide or regional operation. I posted a news article a little bit ago about a stand off with FBI in Washington Co. MD.

Question: When you say "NET1/6" what does that mean exactly?

Also, I recieved a bunch of traffic on the air band air-to-air with unidentified police or of the like on 123.025 MHz AM. Referenced to my post here >> http://www.radioreference.com/forum...n-forum/141150-dc-metro-area.html#post1045237
