Does VLF count? There were several VLF Alexandersson transmitters extant worldwide for radio telegraphy, but they were not long-wave broadcasting.

New Brunswick (13.761kHz and 13.274kHz): 1918 and 1920 to 1948 and 1948 respectively; Radio Central, Long Island (16.484kHz and 15.957kHz): 1921 to 1948; Tuckerton, NJ (16.304kHz and 13.575kHz): 1921 and 1922 to 1948 and 1948 respectively.

The U.S. Navy operated Haiku (Hawaii) Alexandersson alternator TX during WWII, operating from 1942 until 1946.

But it's doubtful that these signals would be received on a domestic set intended for broadcast use.
