As previously stated, nearly all of the activity is on TG 7304. With the new upgrade (thanks GRE) I'm copying mobile units calling "State Highways" on this TG. Sounds like a simulcast of a police related VHF frequency, I heard a partial K-series FCC ID at 1730 and have heard some DLICs and plates run in regards an accident.

I'm pretty confident it's MSP JFK "M" barracks.
The DSP 1.2 update that just went into beta for the PSR-800 has solved all my LSM/CQPSK issues. Thanks GRE.
Think you're right now I think about it- they do call their dispatcher "Highways." Also a mention of a street just off of exit 77 in Bel Air, so that's a yup.
Sorry to doublepost, but on another note: TG 7102, which I've ID'd as MdTA Police PORT Detachment, had the following announcement at 0645: "Communications All units, we will now be utilizing the new 700 system."
Seems like they've switched over operations, at least for a test period.

Any idea what frequency this user set was using before the switch? Looks like 453.57500 -- sound right?

fyi I put my 106 in search mode Saturday 773.0-774.0, no hits.
Somerset County. too far south maybe

I think based on my reading that only the areas from the Bay Bridge up to Northeast Maryland would expect to be active right now. In my travels, I've seen control channels active from Chestertown to the Bay Bridge to Baltimore (and points north?) which seems to match the information that is out there. While down your way over the weekend, I stopped seeing any CCs just north of Easton.

Correct, they shared that freq with the Key Bridge units. This share seems to have held for the trunked TG due to call volume and dispatcher need being the same- I've been hearing K# units on there with the P# units all morning.
EDIT: Looks like 7106 is the Bay Bridge Det (heard Station call an L# unit for a radio check), though I also heard an identical call a few seconds earlier on 7130. If anybody hears any corroborating noises, do tell.
EDIT 2: FYI in case anybody's curious, at least for PORT this is NOT a simulcast of 453.575- they have switched operations (for now at least) entirely to FiRST.

Reports being provided on the P2 overall seem to be pretty good so far.
Questions for all....
What is your setup?
Did you do a straight import or manual programming or combination?
Do you have all sites loaded and letting the radio do all the work or something more exotic?
Can you tell which site(s) you are receiving?
How is reception and decoding overall?
How is the reception when you move around?
I have an "all sites" configuration but I am mostly using two specific configurations in order to hear more activity -- one site 101 with only the CC frequency programmed and the other site 102 with only it's CC frequency programmed. I believe there is activity on site 101 that cannot be heard on site 102 (which makes sense).
Both radios are using the RS 800Mhz antenna.
Even with these configurations, I have hit and miss reception in my house.... but once I find the right spot, the reception and decoding are excellent.
Anyone else?

I'm hogging this conversation today haha so I might as well answer..
Setup is a PSR800 with a ghetto combination of antennas of various reception qualities from the included rubber duck to no antenna (works great battling CQPSK here in BCo) to an Austin Condor (hung from my ceiling right now on a cable but occasionally on the radio). Condor's kicking butt right now mostly because I can grab what I think is the Pikesville site and hear MSP-M with it.
Programming is straight CC-only import via EZScanDG with no modifications (yet). All sites are loaded in the radio. Most MdTA intercepts are coming off the AACo site, and MSP-M is coming off the BCo-Pikesville site (I think, some of my site names are a little dodgy). No other ID'd intercepts yet. My site info is coming off of audio recording processing in EZScanDG.
Reception from my hill in Catonsville to AACo is near perfect with outstanding audio. Reception to Pikesville is dodgy (I think mostly because I'm on the wrong side of the building and hill) but has good audio when receiving. Haven't had much mobile testing ability yet, but I will say that right now Rt 40 west of Rolling Rd sucks, but Catonsville seems alright.

Semi-related observation --
The "Port" dispatcher on duty right now sounds like a familiar voice but I've never listened to MdTA activity at the port before.
The dispatcher's voice sounds like a voice I'm used to hearing on the MAA (BWI) Fire dispatch talkgroup. I wonder if these dispatchers are trained to move from role to role or this dispatcher transferred recently....

Hmmm maybe, I haven't listened to BWIFD in a while. I have heard her dispatching Port (and possibly McHenry) for a long time though, at least a year. Very familiar voice.
EDIT: MdTA does run from a central Communications office, though I'm not sure if that includes TA operations at BWI or if they run from their own command post.

It sounds great in NE AACo. Does the database need to be updated to allow the GRE EZScan software to download the talkgroups that are listed? It imports the system fine, and I'm scanning in wildcard & manual entry mode now- but no talkgroups are automatically brought in from the DB.

The adds to RR won't get picked up for the 800 until Saturday's library rebuild.

The "MdTA Port Police" talkgroup is interesting in the coverage by the units....
The dispatcher is referred to as "port" and the units are P-x and K-x. They've been covering everything from the Key Bridge to Route 10 near Ordnance Rd (traffic stops overnight) to Broening Hwy (traffic stops) near the port in South Baltimore....

I have my two radios locked - one on the AA County site and the other on the Baltimore site -- observing the differences in activity.
7102 ("Port") appears to be active on both sites - this makes sense since some of the active units are in Baltimore and I've heard others (still don't know why) are doing traffic stops on Route 10 in the Glen Burnie area.
7304 (MSP JFK) is (mostly?) a patch from the low band analog channel -and- does not appear to be active all of the time; I suspect, based on patches I've seen on other systems like AA County, that the patch only becomes active and consumes a frequency slot when a true P25 user radio is actively on the talkgroup (maybe just listening). I am looking for indications that a real P25 user is on the talkgroup....
Other talkgroups have been detected but with no real consistency. Perhaps we can expect to see additional users and talkgroups activated each week over the next few months....
EDIT: a user on the "Port" talkgroup just reported he was having trouble transmitting - dispatch (and I) only heard him when he said reported that problem....
