The station operates with 500 watts omnidirectional by day. But because 740 is a clear-channel frequency reserved for Class A CFZM Toronto, WMBG must reduce power to 7 watts at night to avoid interference.^[2]

WMBG programming is simulcast full time on an FM translator station, W228DX, 93.5 MHz.^[3]
