By the way, I too would like to know from others what kind of output powers you are
seeing.  The manual says, "With L2 at its optimal turns spacing (for best harmonic
rejection), 20 meter output will be about 0.3 to 0.6 watts lower than 40 meters."  Also,
"...40-meter power output [should be] 3 to 4 watts with a 12-14 V supply...."

Half a watt, I expected.  Half power, I did not.  Since I'm not playing hard-core QRP
yet (Give me some time, OK?), I'd like to have the extra watt or two if I can get it.
