This hulking Comark (now Thales) behemoth was WHDH-TV's transitional digital channel 42 transmitter. Having commanded it to shut down by remote control, Brian is checking the controller on each cabinet to make sure that it is off the air. (The blower fans and electronics keep on running for some time to cool down the Inductive Output Tubes that these transmitters use in their final amplifier stages.)
