I'm working on a project where I need to know what cities or counties that have a trunk system use Simplex Tactical frequencies for fireground use?
Are they monitored by their dispatcher? Can the dispatcher talk back to them?
IE: Phoenix AZ FD, Chattanooga Tenn FD, etc
I'm trying to make a list of as many as possible.
Thanks for any help,

Re: FD Trunk Systems and Simplex Usage
Fayette County, PA 911 TRS. . . .
Channel structure for Fire Side channel group. . . .
Ch 1-FD_Disp-Dispatch announcements
Ch 2-FD02_CMD-Command channel for officers to talk to 911,apparatus marking enroute,ie comms with 911 center from field units
Ch3-11---FD03_OPS-->FD11_Ops Ops channels for Fire use primarily used for en route communications (note below detailing county terrain. .)
CH12--FD12_COM-->chit chat channel/bs channel/equivalent to CB ch 19 aka non emergency channel
CH13-FD13_XPTC-->crosspatch channel for conventional high band/low band patches to allow communications with air medical transport units
CH14/15--MA14/MA15--mutual aid talk groups to allow fire to communicate with EMS/PD/public works etc
CH16-TAC2-talk around simplex
CH1-15 are talkgroups on the system, CH16 is analog conventional simplex for onscene commmunications
CH16/TAC2 is not monitored by the 911 center
IC sometimes has two portables as scanning a TRS with a conventional simplex channel is less than desirable on occasion (one on FD02 to talk to 911 and another on TAC2 to coordinate/talk with fire ground ops)
We use the TRS for enroute comms due to terrain. . . . County is 850+ square miles and responders are generally traveling anywhere between .5 miles and 20-30 miles to get to an incident. Repeated comms are necessary for everyone to talk to each other until they arrive on scene. . . . .

Re: FD Trunk Systems and Simplex Usage
Dallas, TX FD: Dispatch and operations response on UHF conventional, simulcast/voting repeater. Fireground operations on UHF simplex. They attempted to build a box that would crosspatch fireground to a talkgroup on their local government 800 system for recording, but this never worked right as the radio guys didn't understand how the commanders used their radios.
Fort Worth, TX FD: Dispatch and response on an 800 Type 2 system. Fireground ops either on the TRS or on discrete simplex channels based on the IC's decision. Simplex channels are not monitored in dispatch.
Most other local departments that operate on a TRS conduct fireground ops there as well. In certain special situations, you might hear them go off to one of the interops for fireground comms, if the TRS is totally unreliable.
