I was looking at my Montgomery Fleetmap, Howards Zone was 14, but that might be outdated. Usually what that 15 Bravo is refering to is Montgromery Countys Zone Bravo, Channel 15 on Montgomery Countys radios. On Our system that might me Alpha 1 or Bravo 1 or Charlie 1, since Montgomery is also a ditial Moto system, they come up on our regular talkgroups instead of our interop TGs (A11,12,13, B11,12,13 C11,12,13 or D11,12,13). Now if We (Howard) go to Montgomery County, on OUR radios it is in the Lima Zone and whichever respective channel we are assigned, Usually THIER 7 Bravo. So in short, when they come here, thier radios affiliate on Howards system and they operate as if it was one of our radios. Hope this helps.
