And it was there well beyond that. In the mid-1960s I used a BC-453 to copy
MF maritime CW to improve my Morse receive skills (maritime CW being much
more interesting than ham CW), but maritime Morse in the 420 to 520 kc range
was still very busy when I got my Second Class Radiotelegraph license in
1981. The US Coast Guard didn't drop 500 kc guard until 1995, and the last
regular US coastal station Morse operation didn't cease until July, 1999. I
miss it.
I wonder when, in the US:
(1) The last aviation LF/MF directional (A-N) beacon shut down, and
(2) The last LF (278 kc) control tower-to-aircraft operation ceased, and
(3) The last 3105 / 3023.5 kc aircraft-to-control tower operation ceased.
I have somewhere an old copy of FCC aviation regs that, IIRC, makes it
appear that 278 / 3023.5 kc ops may have continued in isolated instances up
into the very early 1960s. I'd have loved to listen at night to 3105 /
3023.5 kc 50 to 60 years ago.
