[Elecraft] Product Idea - 25 Watt PA for the K3

[Jim Miller]

I'll take a guess.

All transmitters have multiple stages to get to 100-200 watts. Tapping off
the 10w stage was easy to do and makes a nice QRP rig. I used my K3 for
several years as QRP only before getting the 100w amp and eventually the
KPA/KAT combo.
