[Elecraft] Using K2 rant input

[W3FPR - Don Wilhelm]

Vic,

I don't have the full answer, but can offer this 'food for thought' -- The
Rant input (when active) is connected to the output of the K2 T/R switch
when in use, and when the Rant is not being used that point is subjected to
the full output of the base K2 output collector RF voltage - so I would
conclude that it should handle up to 15 watts of RF induced onto the Rant
input jack, but OTOH, I have not tested it.
