Unlike most radio stations in the Northeastern United States assigned to the clear-channel frequency of 1540 kHz (all of whom must sign off at sunset to protect KXEL in Waterloo, Iowa and/or ZNS-1 in Nassau, Bahamas) WBTC has 5 watts of night power assigned, but signs off nightly at 9:00 p.m., give or take live sports play-by-play events.
