With todays solid state dividers obtaining  160 - 190khz from an HF crystal is easy.  However, if you are going to build a non solid-state transmitter today, where does one (inexpensively) obtain a crystal?  There are crystals in the 300 to 400khz range on eBay and it is possible to build a tube type flip-flop to divide by 2, but what did they really do in  the early days of part 15 if a really stable transmitter was desired?
