[Elecraft] Internal Antenna Tuner and SPE Expert Amplifier Questions

[Reinaldo Leandro]

I have been using and Expert 1K with my K3 for the last 4 years. A small and
excellent setup for an apartment.  
My antenna is a compromise no resonant sloper on most of the HF bands, I
have an automatic MFJ tuner ahead of the amplifier. Even barefoot I never
need the antenna tuner on the K3.
It is necessary to adjust the 1K for the default 50 ohms output as explained
in the manual.
