[Elecraft] 80 meters with an R8 vertical ( K2)

Pushing 80 meter RF into an R8 could be very bad for the R8.  The tuner has 
been able to find a match that allows the radio to pump RF into the coax to 
the antenna but that RF *might* be (mostly) going into the tuning network of 
the antenna instead of being radiated.  Overstress is a definite possibility 
when doing that so please be careful.
