[Elecraft] Re: K1 on USB CW

[Leigh L. Klotz, Jr.]

I just picked up a copy of the June CQ in the airport bookshop and p.28 
has a sidebar by K2MGA (CQ Publisher) on the history of SSB:

   Regardless of how the SSB signal was
   generated, the 455 kc USB signal was mixed up
   to 9 Mc.  Using a converted war-surplus
   BC-458 transmitter...as a VFO, the
   4.0 to 5.3 Mc output was either added
   to or subtracted from the 9Mc SSB
   signal.  That produced a USB signal on
   20 meters or an LSB signal on 75 meters.
   (That's the origin of the world-wide
   convention: LSB below 20 meters; USB on
   20 meters and up. ..)
