Owned and operated by Sacred Heart Radio, Inc., it relays the Catholic religious programming originating at KBLE 1050 AM Seattle.
KBUP is one of the oldest radio stations in the United States,[2] and received its first broadcasting license, as KGY in Lacey, Washington, on March 30, 1922.
[3] In addition, the station traces its origin to earlier activities conducted by Father Sebastian Ruth at Saint Martin's College in Lacey.
In early 1916, Saint Martin's College was issued a "Technical and Training School" radio license, with the call sign 7YS, for a station established by Benedictine monk Father Sebastian Ruth, O.S.B.
[7] In July 1921, Ruth upgraded the station to use a small vacuum tube transmitter, which provided the ability to make audio transmissions, and he began a schedule of twice-weekly one hour programs transmitting phonograph records.
[11] In March 1941, under the provisions of the North American Regional Broadcasting Agreement, stations on 1210 kHz were moved to 1240, which has been the dial position of KGY and its successors ever since.
