That’s interesting! I’m sure you hearing CFAX over KNX had something to do with CFAX throwing all of their power towards Alaska.in Alaska it was both CFAX and KNX mixing.. KNX might lead or win or be mostly alone, but nto often and it was often mixing with CFAX, but CFAX never won/lead/was alone. 125 miles NE of McGrath back in 2016, it was all KNX.
HEre in WY? It's all KNX, in the winter, sometimes yu can detect KNX all day. it may be a carrier and not muich more from about 1030am to 3pm in the dead of winter, but its there.. and its audible every night.
One thing I find particularly interesting is the transmitter location for CFAX. They operate from a rocky island just south of Victoria, and have a pattern that directs all of the power north and northwest. I’ve never really seen a transmitter location like that before.
