Maryland uses "Med channel patches" - "patches" being the operative word.

Units in the field call EMRC on "EMRC Call" and ask for a patch to a hospital or hospitals. EMRC then assigned the unit a "med channel" like Med4 or Med8 and EMRC establishes a patch to the hospital requested by that unit. Once the communication is completed, EMRC tears down the patch. The next patch set up on that same "med channel" might be to the same or a completely different hospital.

Each jurisdiction has it's own naming convention for these channels. On EMRC Call, you may hear units directed to switch to "Med 4" or "Med 8' will others might call it "224" or "228" or "Charlie 8". Essentially, they all are really the same thing just different names.

It's been my observation that the Cecil talkgroup in question (4237) has always been used by Cecil Medics communicating directly to Harford Memorial Hospital no EMRC patch involved. The channel has always been dedicated to this purpose in Cecil County. Same as (4238) being dedicated to Union Hospital to Medics communications. Taking away the description is counter intuitive in my opinion.

TG 4237 MED 4 "while technically correct"

Seems less useful than updating it as..

TG 4237 MED 4 UM Harford Memorial Hospital (Havre de Grace)

That's all I'm saying.

Yesterday, that TGID (MED4) was used for a patch to Union Hospital. The MED channels are not dedicated to any given hospital.

This is correct. The Talkgroups are RF patches to the UHF med channels.

OK, Thanks.

These are all separate radio channels or talkgroups on different systems, not the same radio channels called by different names.

I think he was saying they're all functionally the same potential talkpath, despite system differences.

DisasterGuy · Feb 9, 2016

Correct, they are static (causeway) patches between EDACS talkgroups and UHF control stations that function as subscribers on the EMRC channels.

Cecil County Ramps

I've been tracking and monitoring this system since shortly after it went on line. My apologizes for not contributing earlier but I was precluded from doing so. This information was obtained in several ways, monitoring via Unitrunker, empirical observation from radios on the system and most recently monitoring via the 436HP.

The attachment titled "Fleet Maps" was the original radio ramp (zones) configuration that CCDES shared via their website back in 2006. The text file is the sum total (basically) of my research on the public safety portion of the system. Any information (TG ID's) that have "?" next to them are those that I have not personally confirmed from a system radio and are my educated guess. I have not submitted this information to the database at this time.

FWIW,

Some unconfirmed TG's are listed here...

Cecil County (MD) Unknown Talkgroups - The RadioReference Wiki

would be great to have some confirmed/submitted!

I frequently make trips down to Perryville for work. This last trip I brought my BCD436HP, with the appropriate ProVoice update installed, but heard no traffic on the system. All my site information is correct per the database, and the radio appeared to be locked onto the control channel normally.

Any particular adjustments you locals could suggest that might aid in this?

I've monitor that system with the 436 and didn't do anything special as far as settings. It isn't always super busy so might it be a time of day/length of time in the area thing?

I had same problem a couple years ago as posted on this thread.
Download zip file from here and ended up working fine after that.
Read page 6 of this thread.

It's been a while - now curious, if the direct import doesn't work, why - after all this time.

Reading back through the referenced thread with the zip - seems manually entering the system (at lest for me) worked fine. I think on ore recent trips through the area, I did a simple and direct import from the library and recall (I believe) it worked without any special "work-arounds"....

Updated HPE 01-2018

Here is my up-to-date personal HPE for Cecil, If your HP scanner does not receive when in the area then maybe the provoice uprgrade did not get activated in the radio. (Just a thought)...

FYI, This file includes all the unidentified TG's to date and RID's as determined by the wiki and personal observations. It it set up by departments that differ from the RR DB. (But I like it better this way)

Assuming you are near Cecil -- can you go ahead an import with Sentinel (no special programming) and verify it works? I'm pretty sure it does....

u2brent · Jan 28, 2018

HPE import

You may import the Sentinel version, but it won't have all the RID's and unidentified TG's that have been observed. Just a thought..

Hit the ground running..:lol:

To each his own.

troymail · Jan 28, 2018

Just want to know if the import via Sentinel works for you with no special effort required....

u2brent · Jan 28, 2018

Understood. I'll try it and report back when I get a chance, unless someone beats me to it..
AFAIK the Sentinel Version should work..

u2brent · Jan 28, 2018

Findings

Ok, I ran the Sentinel Version and it does work.
I would recommend changing the modulation to NFM from Auto.
& enable ID Search. (Otherwise you miss traffic on the TG's not in the RR DB) 4481 in use today..

Using my uploaded HPE is still gonna yield better results IMHO.

Under Display Options, Display Mode in the Profile should be 2 to view RID's either way..
That's half the fun..
