[Elecraft] Power Amplifier

[Benny Aumala]

Who says there is nothing new in amplifiers?

PA is not battery driven, so 12V headroom is not a question.

Look what is presented in ADT 200A transceiver.

This rig use adaptive predistorsion. New amplifier could
use it too with feedback to K3 ???
And have 3rd IMD much better than we are used to.

Not to mention schematic architecture possibilities and
operative adaptation to expedition and contest needs.
