[Elecraft] K3 PA

[Eric Swartz - WA6HHQ, Elecraft]

These are part of the PA feedback network that stabilizes PA gain over 
temperature and the 1.8 - 50 MHz frequency range. They are elevated 
above the PCB to improve heat dissipation and stray coupling. They are 
installed during regular manufacturing of the KPA3 board.
