We have racked our brains, but cannot think of any other Canadian stations with only three call letters besides CKY, CKX Brandon and those owned by the CBC.
I think we may have posed the question previously, but Today in History this morning brings it up again: have there ever been any other 3 letter call letters used by Canadian radio or TV stations?
When I wrote the above 3 years ago, I did miss one: CHU, the shortwave time signal run by the National Research Council from Ottawa.
Anyone remember any others that may have existed in the past and/or exist in the present?
