[Elecraft] KX1 Power options

[n0evh]

Be gentle with me folks this perhaps could be a dumb idea by a certified novice
circuit designer!

Was thinking it would be nice to get a full 4 or 5 watts out of the KX1 at
times, but would like to avoid external power packs of 12 volts.  I am willing
to have less total operating time off the internal AA batteries.  I have
considered Paul's approach of inserting half size AA batteries to boost the
overall voltage of the internal AA battery holders.

Would it be possible to use a dc-dc converter chip to boost the 8-9 volts of the
AA's up to 12-13 volts and keep the circuit internal to the case by heatsinking
it to the bottom of the case near the battery packs and in the small space
below the tuner?

A small switch could also be added to control this feature giving one a quick
way to add or substract 3db of power in the field.
