[Elecraft] ****KX1 Lithium Batteries****

[John Buck]

Interesting information.  But one caution.
The 3.6V AA Tadiran tl-2100 initially looks perfect for KX1 usage.  But 
it may not be useful
It is rated for 2 milliampere long life usage.  The Tadiran site does 
not offer information that I found for higher current operation.
But 4 watts with 4 AA cells at 2.1 AH sure would be interesting to know 
if they can deliver the current.
