[Elecraft] [K3] 150 watt "boots" for 160m

[Julius Fazekas n2wn]

Hi Brian,

Was that in QEX? I seem to recall an article about this in the past couple
of years. You are right all I wish to use it for is CW.

I know at least a few of the responders understand what I am trying to do
and why. LP categories in 160m contests allow power levels to 150 watts.
Most of the time 150 watts would buy one nothing, but it is worth having
just a touch more umph if the conditions are marginal on the other end. I
can't squeeze anything more significant out of my Tx antenna, if I was lucky
maybe 1/2 db... maybe.

something under $300 in the way of a simple amp IS worth trying and may have
been enough to have added 3 multipliers during ARRL160 because those guys
couldn't quite pull me out. There's no downside to trying it.

Thanks for all the thoughtful answers. Don't think I'll mess with the K3 PA
and I don't want to move into the HP category :o)

73,
Julius
