CBW , the Canadian Broadcasting Corporation (CBC) outlet in Winnipeg, Manitoba traces their origins back to 1923 when it signed on as CKY. In 1933, CKY became a partial CBC outlet. In 1948, CBC purchased CKY outright and started to use the call letters CBW. The Call letters CKY were transferred to a new commercial station. CBW programming is re-broadcast on several FM outlets in Manitoba.
CBW was an easy catch in Spokane, and I have also heard them several times in Maryland. They sent the two QSL cards for reception reports sent to them.
