The Canadian Broadcasting Corporation (CBC) English Language outlet for the Maritimes signed on the air in 1948 on 1570 kHz. In 1955, CBI moved to 1140 kHz where it remains as of this writing. There are plans for CBI to vacate 1140 kHz to complete a move to FM. However, this has not happened because of issues regarding adequate coverage.

CBI occasionally dominates the channel here in Maryland, overpowering WRVA in Richmond VA. They replied to my reception report with the QSL card seen below.
