I just logged my first Canadian AM station in this current mediumwave DX project: AM 690 CBU (CBC Radio One) in Vancouver, British Columbia, Canada. CBU uses a 50 kW transmitter, and the station is approximately 800 miles from me. This station was received by my Eton E5 with no external antenna. I previously logged this station during my autumn 2006 mediumwave DX project.
The signal is strong and clear, and currently features a show with an eclectic music selection. For example, a Paul Anka song was followed by "Woman from Tokyo" by Deep Purple. According to www.cbc.ca, this show is "In the key of Charles", hosted by Gregory Charles. At times, he plays a piano and sings along. I like it! I don't think I've ever heard a radio show like this before.
