[Elecraft] New Elecraft K1 User to be

[Donn Kuse]

Hi all,
I'm now awaiting my first K1, 20/40, complete with noise blanker, ant
tuner, internal battery adapter and more.   I probably won't be using
its keyer for a long while.  I like the straight key for CW.
Fortunately (in my case), it's already built and being tested with
additonal modifications and an extra KFL1-2 for 20/15.
My one question, right now, is what external power supplies are used for
the maximum transmit output?  I'm not even familiear with what type of
external power connection is used.
Would also like to hear from other K1 users.    Also, how do you use the
built in antenna tuner?
Thanks,
