[Elecraft] More power from K2

[Bill Johnson]

Johnny,

The difference in real signal strength for a receiving station if you were
to go from 15 watts to 20-25 watts is about zilch.  Going from 15 watts to
60 watts is approximately 1 S-Unit.  I wouldn't bother going there, besides
the changes are more work than it is worth.  It may be a better option to
order the KPA-100 and increase  power to 100 watts which is 10 db, closer to
2 S units.  Or, in the alternative, focus on the antenna which is the least
expensive alternative, esp. if you are into wires like so many of us are.
Then, of course, one could try one of the more exotic, expensive verticals
with lots of ground wires, then 1 watt would accomplish alot.

I notice that battery technology has been improving. 
The internal lead-acid battery used in K2 can be
replaced by newer version with capacity of 3.5Ahr
instead of the original 2.9Ahr.  The new version can
be found easily in Hong Kong at a price of say US$10.

Therefore, my question is "Is it possible to modify
the K2 to deliver a RF output of something around
20-25W?"
