[Elecraft] K1 on USB CW

[Allen Ward]

Both the Central Electronics 10B and 20A  generated EITHER USB and LSB at  9 MHz.  I owned one each of these rigs.  Mixed with 5 MHz (or various multiples thereof) one could operate from 80 to 10 meters.  You selected the sideband by flipping a switch on the CE unit.  The best part was the magic eye on the 20A which was used to indicate the suppression of the carrier and output tuning.  Folks tend to forget what great sounding CW came out of these "QRP" rigs and the amazement of working someone with 5-10 watts.
