Henry county EMS

[msmakm67]

I have been monitoring the Henry county system for awhile and you never hear EMS. When I have been in town, I see mostly VHF antennas on the ambulances. Are they operating on some system that is not in the database?

Henry EMS is operating on the Henry Co UHF DMR trunked system but they are probably running encrypted. Sometime back most of the agencies on the system went encrypted.

I heard the EMS Traffic last week while working in Henry County.

Do you know the talkgroup id ? The one listed 131, never seems to have any traffic.

Also, does anyone have a updated talkgroup list? There seems to be more talkgroups than what is listed on RR

I am the one that listed the TG's for the Henry County System 131 is correct I am using a 2 SDS100's in my mobile setup.
I hear them Murry to McKenzie and just outside Dover to the edge od Dresden with no problems.
My TRX-1 and BCD325P2 miss calls connected to my triband antenna feeding my Stridsberg 4 port Combiner.

Every ambulance in TN is required to have a VHF radio for transmitting on 155.205 / 155.295 / 155.340. There is a weird exemption for a non-specific county (Shelby, perhaps). Likely not their primary transmitter, but they definitely are required to maintain the equipment.

Now, depending on the specific area, they may or may not ever actually use the VHF radio. YMMV.

I am down near Paris landing and should see TG131 but I never do. I am running SDRTrunk with three doggels and a amplifier attached to an antenna up 35 feet on a tower. Also there seems to be TG IDs showing up that are not listed {92,70,99,94,37,100}.

They do in PARIS use 155.205 to talk to Medical Helicopters and 155.340 to talk to the Hospital. Dispatch info is on the Henry County DMR Trunking System that has 5 Simulcast Sites.

Okay. I will tune my portable into the vhf channels, thanks.

155.205 and 155.340 are SIMPLEX and you will only hear 5 miles or so with your scanner.
The Hospital has about 100 foot Antenna and can hear the Ground units 10 to 15 miles at best.
The Aircraft talks to Ground Units 5 to 7 miles out.
