[Elecraft] K1 on USB CW

[Ron D'Eau Claire]

It took people a long time to catch on to the difference in power levels. I
had a Viking Ranger back then. On AM phone it ran 65 watts by the common
measurement of the day. That was d-c "input" to the final tube, of course.
At a typical efficiency of 75% that provided 49 watts output. 2/3 of that
power, or 32 watts, was in the carrier when the signal was 100% modulated,
leaving 17 watts divided between both sidebands, 8.5 watts per band. So my
"65-watt" Ranger was equivalent to an SSB rig producing 8 or 9 watts output.


"Worked the world" with that Ranger on AM "phone" as well as CW. And it was
a whole lot bigger than my K2. And then there was my HRO-5 receiver which
was as big as the Ranger <G>.

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. Allen
