[Elecraft] K3 - CQWW SSB Observations - R U kidding?

Metal film resistors are notoriously fragile.  They will typically meet 
their published dissipation specs just fine, but they go from being OK 
to being an open in a flash (literally) when overstressed.  I personally 
would never use one in any application where the power they were 
expected to handle wasn't rigid controlled.  Check with any industrial 
control manufacturer and you will hear the same story.
