[Elecraft] External 12V with the KX1 necessary?

[Michael Madden]

Hi group,

I've been having a lot of fun with my KX1 out near the
San Francisco Bay.  I have worked coast-to-coast in
the US and DX highlights include FO5 Tahiti and CM6
Cuba.  

A question on power output: what are your opinions on
the value of 12V from an external battery?  I.e., 4W
vs. 2W?  

I have had some intermittent ATU problems with the KX1
when on external 12V, so I often need to revert to
internal Li AA's.  I am wondering what your opinions
are on the need for 3dB gain on the KX1.  

I have tried to do some on-air A/B testing between
internal and external power.  The guys on the other
end usually say "FB on 2W."  But I have also gotten
some "are you still there."

Anyone else do such A/B testing on the air?  Any
conclusions?

Thanks,
Mike N9OHW
