That was a Barn Fire, Opps was on Fred co Tac 30. They also used "sub groups" 31-34 and at some point water supply was on Tac 40. Most of the time ECC only monitors the main Tac Talk groups (Tac 30,40,70,80,) and not the "sub Tac talk groups" (Tac 31, 32, 33, 34. 41, 42.....). most of the surrounding jurisdictions all have each others systems and main/most commonly used talk groups programed in their 800 TRS radios, or in Wash co the stations that commonly run into frederick have a seperate Frederick co TRS radio. The Ft. Detrick TRS Radios use a detacated 400mHz TRS talk group thru a hardwired permenat patch to Frederick's 800mHz TRS Talk Groups. If you look in the Data Base for Ft. Detrick's System you will see that thay only use selected Frederick Talk Groups. this was to get away from carring 2 radios, but you may already know most of this.
