info from online app from MBHSR or whatever it is called

for Ted Williams Tunnel (TWT] + O'Neill Tunnel + Sumner and Callahan
Tunnels + Central Artery North Area (CANA] + Prudential + MBTA Subways

all have BFD Ch1 and Ch 4

MBTA Subways also have MetroFire Red

all have BEMS Tac 1 + Tac 3 + Med 4N + Med 5N , and Med 8N except that
MBTA tunnels only have BEMS Tac 5

for police ... BPD Ch 1 is in TWT + CANA + MBTA Tunnels ... also ...
state police TRS is in O'Neill Tunnel .... also ... BAP4 is in MBTA
Tunnels

=========

wow ... way complicated ...surely MSP has 800T in the other highway
tunnels since they are the primary police agency for those tunnels

can see why this would affect Marathon radio planning

anyone know if any of these radio channels can be used simultaneously
in various tunnels at the same time?
