From my location on central Vancouver Island on Feb 12, 1996 at 615
UTC I heard HJCY Bogota , Columbia on 810 kHz. It was a strange
night as KGO usually booms in here. There was not a trace of KGO.
What I did hear was a station jingle and "Radio Caracol". Was using
a GE Superradio and no external antenna. I heard them poorly under
KGO again in Nov but not since.

My strangest AM radio experience was in the early 1970's on a
hike down the west coast trail on Vancouver Island. I got up a bit
before sunrise and moved down the beach so as not to disturb those
still sleeping. I pulled out my trusty RS Flavor radio (Lime) to get
the news. There were no North American stations audible. But the
band was full from end to end with Japanese stations.
