i have been hearing more MSP H (LaPlata) radios on PG site. Would this mean they got new radios? Coincidentally the busier traffic started right at August 1….

……..also was at Reagan airport Thursday (no man, not for THAT 🤣) and both Charles and PG sites come in pretty clear on a SDS100.

For those that monitor the Montgomery Cell, is Seneca State Park Ops (8377) active yet? I have noticed a few times that Seneca Contact Station (Gatehouse) operating on DNR Interop Channel.

I have noticed and have submitted to RR that the MSP Brk N Rockville is on the MD 1st system besides the Montgomery County system using Talk Group 7346. I have been also running Unitrunker and it does show up without the MSP listing for Barracks N Rockville as well. I have heard and caught on Unitrunker at least 7 times within the past 3hrs. I have also heard Barracks A Waterloo on the Montgomery Site as well and I am running a log also. Thought I would pass it on so those of you who are monitoring can update accordingly .

That’s been that way for weeks, I also did a submission, twice but I guess they rather update conventional discovered frequencies in the Maryland database.

CHART 9700 units report that they can’t get out on their portable radios from Rt.15 at Rt.340 to Rt.40 (big gap) and have reverted to their CAD or cell phone. Unit 9700 states he has had this issue for the last 3 days and has notified personnel. Very interesting

The first place that I would look is at his portable radio.

8458 appears to be another UMCP talkgroup. It sounded like activity related to the stadium.
I was thinking the same thing it sounded like college park units, which was a little odd since stadium activity was supposed to all be on the Event talkgoups. Next game day is Sep 30th hopefully it can be verified.

Notes from the RCB meeting last Wednesday:

FY2025 budget requests $17M Capital; $17M Operating.

Several organizations requested access to the FIRST system. All were approved. The Maryland Judiciary earlier had requested to be an Interop partner. Now they want to become a Primary user, requesting two tgs: a Main and a Tac. Garrett College Security also wants to become a Primary user, requesting 1 tg for their operations. Morgan County WV requests to be an Interop partner, as well as the USPS Postal Inspection Service. The Maryland Hospital Association is being sponsored by DHMH for access to DHMH tgs. Worcester County is requesting to become a Limited Primary user with 8 tgs to be used as backup if their radio system goes down, like some other counties. A discussion of capacity ensued and recurred throughout the meeting. There is an acronym "PACE" emerging in the radio world: Primary, Alternative, Contingency, Emergency. How to Create a PACE Plan – American Contingency

Smart Connect / Critical Connect. Smart Connect is the technology that enables a subscriber to use WiFi or cellular data to access the radio system if the RF signal fails., provided you have a compatible subscriber (and pay the subscription fees.) Critical Connect is the technology that allows radio systems to be linked virtually / "in the cloud". A test was conducted with Frederick County (who also has a Critical Connect license) recently to prove the concept / operations which apparently worked. The technology could also link PPT cellular services like FirstNet and Verizon's competing preemptive Public Safety PTT / data service. Queen Anne's County and DGS are considering implementing the technology.

There was discussion of emerging third-party solutions implemented by users "illegally" accessing FIRST which could potentially cause problems (as a tangential compsec person, I find this to be particularly troublesome). A new policy about these devices and software will be published.

T1 conversion backhaul design is complete, and Motorola is due to wrap up its infrastructure survey by end of year. New equipment to support MPLS has been ordered, and staging will be in North Carolina (not Schamburg). The conversion will be complete in September 2025, and will go live by Zone, Zone 5 having already been completed.

Coverage Improvement Program. The Swallow Falls site is behind schedule due to lingering effects of COVID on the supply chain. But they expect the shelter to be delivered in a few weeks, and the site should go live in January 2024. The Greenbriar BDA site got their new 75" telephone pole and is awaiting antenna installation in a few weeks. Go live is Nov 2023. The Davidsonville site just got their construction permit from Anne Arundel County (not an easy process) and equipment is ready to be installed. Go live date is also Nov 2023. The new Cumberland monopole site has been identified and is working through some real estate issues (as are some other coverage improvement sites.) The Patapsco State Park site is awaiting decisions on exact site equipment placement. The Queenstown site on SHA property will require some civil work to expand the parking lot. QAC is paying for the shelter. The Elmer School Road site in Montgomery County is not looking good. There are questions about the condition of the tower, and the private owner is waffling about the rent. However, there are options to co-locate on other Montgomery County sites in the area to provide better coverage in the Potomac River valley. It might end up being two new sites. The DC ASR site has been awarded a grant from the MWCOG, which is huge. The grant pays for the capital costs, and the state will pay for the operating costs. The site will not be at 4D, but closer to the Mall. The companion Virgina site is still desired by the NOVA counties, but so far they are unwilling to pony up the construction costs.

The BDA pilot project. Funding was made available to install BDAs in schools and other buildings where coverage is marginal. They are focusing on Primary user counties. Some other counties already have (or are actively installing) BDAs in their schools and buildings for their systems and add FIRST frequencies as well. The first two sites are an elementary school in Talbot County, and a courthouse in Garrett County. It turns out the school in Talbot is scheduled for a $30M renovation which will delay the project. And it was determined that a new site on a nearby tower would be a better solution for the courthouse project. So they are trying to identify alternative sites to test BDAs.

There are still FDMA issues with Delaware, but they are requesting about 50 TDMA radios a week to be authorized on FIRST, so it will be a moot situation when they move to their new system next year.

The FIRST sysadmins are making a presentation to the FCC about the interference issues they are experiencing in the 700 band. Curiously, they have the support of the major network operators to address the situation. This suggests to me that fingers will be pointed at device manufacturers.

Some board members expressed concern that the FIRST system is becoming too popular, assumably with federal users wanting wide area coverage vs. a desire for interoperability. My view is if you build it, they will come. Perhaps the state could solicit more funding from the Feds to support their increased usage. I'd hate to see parochialism interfere with interoperability or practicality.

A disturbing comment I heard from one board member was the suggestion to make the RCB meetings non-public for perceived security reasons (a likely violation of the open meeting law.) I find this to be more of a mid-level bureaucratic over-classification tendency than addressing any real security concern. Nothing that is said in these meetings is particularly sensitive, they are more like status updates. FIRST has technical and user group meetings that are rightly non-public where specific security issues can be addressed.
