I recall searching the FCC files just as the expanded band was opening up and finding a large number of low power beacons licensed to oil production companies in the Gulf between 1600 and 1700 kHz. There were also some high power licenses to power companies in this band - mostly in FL. I suspected that these might be power line subcarrier control circuits. Maybe these activities were moved up above 1700 kHz to make way for the expanded band.
