We don't know what effective radiated power and antenna heights these stations [1] were using, so we can't pinpoint the areas of interference, but here are the conflicts [2] : 87.7 in Dorchester MA: Operates on same frequency as low power TV station WVCC-LD/Westmoreland, NH (Bridge News LLC) blocking reception of much of WVCC's coverage area (out of band on TV Channel 6 spectrum [3]) 88.5 Dorchester MA: No major interference (other than to fringe WWRN areas) 89.3 Boston MA: No major interference (other than to fringe WCDV-LP and WNPN areas) 96.5 Brockton MA: Uses same frequency as W243DC/Boston (Gois Broadcasting) 100.1 Brockton MA: Uses same frequency as WBRS-FM/Waltham (Brandeis University) 100.1 Mattapan MA: Uses same frequency as WBRS-FM/Waltham (Brandeis University) 105.3 Brockton MA: Uses same frequency as W287CW/Methuen, MA; operates over digital sideband of WWLI 105.1 FM/Providence, RI (Cumulus Media) within it's service area 105.3 Randolph MA: Uses same frequency as W287CW/Methuen, MA; operates over digital sideband of WWLI 105.1 FM/Providence, RI (Cumulus Media) within it's service area 107.5 Mattapan MA: Operates over digital sideband of WKVB 107.3 FM/Westborough, MA (K-Love) within it's coverage area Just over half of the interference is to independent broadcasters. 4 of 9 are unauthorized analog stations operating over a licensed digital broadcast (meaning, they probably found what they incorrectly thought was a blank spot on the dial).
