Signal Echo Foxtrot is a transmission from broadcast tower LP8 located northeast of Montgomery County Reservoir.


The drainage chamber is located near the tower to the east, a sealed cistern just over the cliff face. Near the ham radio is a motorcycle handbrake and a motorcycle gas tank alongside a copy of Big Book of Science. The remains of the former occupant can be found protruding from the rubble.

  • There is a red "X" under the ground seen using no clipping mode (tcl in the console), similar to the other sealed cistern at WKML Broadcast Station.
  • When using the console command 'tcl' players can see that it is not in fact a drainage chamber but instead an escape route from the train tunnels. There are two train tunnel segments which run parallel to the sealed cistern.
