the ultimate rig..

[VA3OL-2]

I have a K2/100, with the ATU.

It is almost the perfect radio...

But as I get closer to RV adventures I long for a rig that will put out 40 or 50 watts with less than 10 amps DC input.

Bill,

How about just turning the power control on the K2 down to 40 watts and
measure the key-down current draw.  I have not checked, but I believe it
should be in the vicinity of 10 amps.
In any case, whatever the current draw, think about the duty cycle - a
50% duty cycle (a continuous string of dots) is very high for ham radio
(you do spend some time listening), so even if the peak current draw is
close to 20 amps, your average current draw will be less than 10 amps.
Maybe I missed something, but I think you already have a transceiver
that qualifies to your requirements.

73,

If he were to peel one turn off the output transformer, from 4 turns to 3,
it should be just about right.
