Which TGs are they using to access Med channels since they seem to be regionalized?

Site 1.28 also shows up as a neighbor of Washington Simulcast site 1.20 , Lambs Knoll site 1.17 and Gambrills Mountain site 1.16. Nothing showing up on 772.36875 yet.

Makes sense. This site was prioritized to improve coverage in the Catoctin Mountains and support the G7 Summit this summer, however that meeting was cancelled due to the COVID-19 pandemic.

I heard..
2224888 Amb27 Anne Arundel on 7R3 Med1 TG 7609
2225602 Anne Arundel MCC1 on MD Call TG 8113
from Cecil
If you only listen to the Towson ASR, you will most likely hear nothing unless a radio is affiliated with the site, you need to listen to a Simulcast system. On the EMRC 7R Call, you should here the EMRC operator answer the field units as that is patched to the County EMRC call channels, however the med channels are not patched. In the Baltimore Metro area, the locals use their own systems for consult, you are most likely to hear Cecil County units, however they still like to operate the mobile in their units on UHF(hard to break habits). There will be no Fire/EMS in the CMARC Region as again they have their own systems, also any full time patching of systems can take up unnecessary resources on the MDFiRST system if those patches are really active (most of the metro area), most patches are made when needed and broken as soon as they are not needed. In reference to SYSCOM if there is a radio affiliated to that talkgroup in the Zone or area near you, you will hear it, if not, then you will not. Since I do not work for MIEMSS anymore you may not hear SYSCOM as often in the Balto Metro, I used to have my portable on 24/7 on that talkgroup as it would always let you if there was an issue on the Low Band side.

Which is sad for AA cause if they knew their portable radios, they would know they have access to EMRC via their 800 system.
Cecil County is using 7R3 Call and Meds even though they are under Region 4, they can also use the 7R4 Call and Meds when transporting into Kent.
Kent down to Dorchester can access 7R4 Call and Meds, I am not sure what Worcester, Wicomico, Somerset and OC use other than the UHF system, I know in the past Wicomico and Somerset used UHF extensively, but now since they have their own systems I am not sure what they use.

It was unusual, because they often use their 800 system for consults - not sure why they were having issues.
Photoguy had mentioned that some AACo units were using FIRST MED TGs which is atypical, which makes me think AAACo was having problems with their 800 system MED channel connectivity. I guess they would use 7R3's as U2brent mentioned.

The deterioration in the AA County 800 MED channels is hard to miss. The ER's can't hear/understand the field units, connections are dropped, and the ERs are barely audible. The frustration on both ends is noticeable.
I'm sorry I screwed this up:
All Region 3 Jurisdictions have access to the information for programming the 7R3 Call and Meds, using them is at the discretion of the County as to whether they want to program.
All Region 4 jurisdictions have access to the information for programming the 7R4 Call and Meds. Kent to Dorchester uses them the most as they are on MD FiRST.
All Region 1 & 2 Jurisdictions have access to the information for programming the 7R1 Call and Meds, Allegany and Garrett use them, however the MIEMSS UHF system is still there to use, Washington County can use their system for consults, but mainly use the MIEMSS UHF System.
The MIEMSS UHF System last I heard was going to remain in place and continue to be used, it was not going to be taken down.

FWIW,
This was sorta gone over before..
forums.radioreference.com
I can verify that whatever is on...
FiRST
7R3 EMRC Call TG 7608 is carried/patched on UHF Med 8 463.175 C167.9
7R3 Med 1 TG 7609 is carried/patched on UHF Med 73 463.1687 C167.9
Not sure about..
7R3 Med 2 TG 7610 because it's only used when MED 1 is already assigned.
it's likely on one of these..
Med 9 Disp 462.95 C167.9
Med 4 463.075 C167.9
Med 53 463.1187 C167.9
Med 6 463.125 C167.9
in Cecil County

Maryland FIRST 700mhz TRS
Makes sense (sort of): 7R3Med1, although I think Cecil is Region IV (7R4Med1 / 7616) MIEMSS Radio Regions don't exactly match the Adminstrative Regions

This past Friday as I was coming back from Baltimore around 8am I heard AA EMS using 8Call90 and 8Tac93 for EMS Ops and Hospital contact. I guess they were still having trouble with their own 800 system as well.
That's interesting - I didn't know that know the 800 interop channels could be patched to hospitals if this is what you are saying. Note that the 800 interops are not part of FIRST.
yes i did AA med center come back on 8Tac93 and it sounded like they were on a portable radio that they were using. AA EMS would get the call on 8Call90 and ask what Tac channel to use and was told to use 8Tac93
I was using my Tait TP9435K Portable radio to pick them up with and a BCD996P2 which i have mounted in my van as well.
If you are saying that the hospital was using a portable, that suggests they are bypassing MIEMSS. The 8TACs are supposed to be controlled by MEMA. They are not simulcast, and only one channel pair can be active in an area at the same time to avoid interference. Very strange.
Unless they were using the portable as a work around since they were having trouble with their 800 system and was told by MEMA to go ahead and just give AA a call and AA would have someone monitoring the portable full time
