In Greater Media's transmitter room, we see the four identical backup transmitters, one each for WBOS (92.9B Brookline), WTKK (96.9B Boston), WROR-FM (105.7B Framingham), and WMJX (106.7B Boston). They're all BE units, possibly FM2Cs. (Scott thinks this is the old WBOS room from pre-consolidation days.)
