>I wonder when, in the US: >(1) The last aviation LF/MF directional (A-N) beacon shut down, and Had to be after the early 1970s. When I was a boy and got my first ham ticket in 1971, there were still A/N beacons. Weather was still on LF at least until the early 1980s. I remember Loran "A" on 160 mtrs, too. God..... I'm *old!* No fair! 73 Dave S.
