[Elecraft] KX2 Power supply

[Bill Lederer]

Friends:

I like to use my KX2 in my office with a wire out the window to a tree,
largely for listening, e.g. to ARRL code practice. I normally use the
internal battery and charge it up ever couple of weeks.

I am wondering if KX2 owners have used a DC supply to power this--short of
getting an Astron or equivalent--one that is just the right size that can
power a 12-watt radio.

Thanks.
