[Elecraft] KX1 Output Power

[Fred Jensen]

If you're willing to spend about $40, a small [like 750mAh] Li-Poly 
battery will work great.  Mine is a little smaller than a small box of 
matches, 12V for about 4W on 40/30/20, and it will last through a 4-hr 
Flight of the Bumblebees.  You do need an Li charger.  Mine would easily 
fit inside my KX1 but I really don't recommend that, my motto is, "Keep 
the chemistry lab on the outside of my radio."  You'll find them at RC 
Model shops.
