Not quite, though a common misconception. In the commercial broadcast allocation Canada owns the range CF to CK. Some might notice that CBC stations often start with the letters “CB”. This technically belongs to Chile and was “borrowed” by special arrangement.
One might note that it’s no coincidence that Canadian aircraft registrations once also were of the form CF-xxx. They were changed to C-xxxx later when the number of registrations grew tremendously.
All these letters come from the allocations set by the International Telecommunications Union, mainly for broadcasting but aircraft registrations follow closely. Thus the United States has the allocations K, N, W, and AA-AL. K and W are used for commercial broadcast stations, broadly west and east respectively, N for aircraft registration, and I believe AA-AL are for amateur radio. X was once used for experimental broadcast stations but was never official.
VO was once assigned to the independent country of the Dominion of Newfoundland! VA-VG remain allocated for amateur radio in Canada.
Straddling the border, Louisiana makes for some interesting pairings. Former governor Noe ended up with stations KNOE and WNOE.
I’m not related to Charles DeWitt White, so I don’t have any particular insight about what happened to the log, although http://americanradiohistory.com has scans of all the issues. (Growing up I always used to buy Vane Jones’ “North American Radio-TV Guide”, which you could get at Radio Shack (RIP)).
this was (partially) carried over when ICAO developed four-character airport codes. US airport codes start with “K” (e.g. DTW is “KDTW”) and “C” is used for Canada.
