This happened about 50 years ago, although I do not remember the precise year.

I still have the oscillator section of my first LF xmitter.  It's an 
Crystal OX-1 board with a 189 kc xtal.  I built the xmitter about 1965 after
reading a an article in an electronics magazine about the Part 15 rules.  A
schematic was included using what I believe was a 6AQ5 for the power amp.  So 
fairly sure the Part 15 rules for the 160-190 kc band was made prior to 1965.
